What's up everybody?

Welcome back to Make It Custom.

Thank you all for being here for this video.

Today we're going to go over the basics of MIG welding.

This is something that everybody needs to know.

It's something that could be confusing if you're just starting out.

How to set up your machine, how to listen for or look for the different things that could be wrong with your weld.

So we're going to see how, you know, your wire speed, your voltage setup, how your technique could affect your weld

and what my favorite techniques are to do mig welding on steel let's get into the video all right

so what we're going to learn about in this video is just the basics of mig welding

i'm using a lincoln electric sp 175t i bought

it on craigslist for i think 450 bucks with the cart

in the bottle just as an extra welder in case i run out of gas

or whatever somebody else is working in here it's a great little machine i've got 030 wire in it

and i've got 75 25 gas mix 75 co2 25 argon there are a couple of different gas mixes

that you can use but that's a really common one

and it's the only mixed gas i use in my mig welders this machine it's pretty basic it's got voltage

and wire speed you've got uh you know a b c d

or e for voltage

and we've got uh you know just variable wire speed these numbers don't really matter every machine is a little bit different.

My Miller has a digital readout as to, you know, feet per second or feet per minute on wire speed,

and it also has a digital readout for voltage.

So I want you to be able to understand how to

set up a MIG welder without looking for 17 volts and 200 feet per minute wire speed.

That shouldn't matter.

I want you to be able to listen to it, be able to look at it, be able to hear it, make a good weld.

That's what we're going to do today.

We're going to focus on setting up the machine, a little bit of technique, what technique I use.

Everybody's got a little bit of a different signature as to how they you know whip their welds around

when they're mig welding you're either making c's you're whipping and pausing

that sort of thing i'll show you the way

i like to do it this material is just 10 gauge steel

this is very common this is kind of what most frames are made of

if you're building a hot rod

or whatever i use this stuff a lot for brackets

but the same thing goes on all thicknesses of metal on how to hear it

and how to see it to know that you're making a good weld

so what i'm going to do is i'm going to set the machine wrong

and let you guys listen to it and look at it

and see what's wrong with it and then we'll get into setting it right okay

so what I'm gonna do first is let you listen to what it's like

if you don't have enough wire speed basically it's something

that a welding teacher told me one time

and it really sticks in my head is you want to

hear like the perfect temperature of bacon frying like you got a mint pan

you got a fresh thing of bacon and you drop it in there

and it's like that's what you're looking for with MIG welding

a less scientific way of trying to figure out your correct settings.

So I'm going to have not enough wire speed.

Basically, you're going to hear a little bit of like a slower sizzle, and that indicates that you don't have enough wire speed.

I'm going to put it on C right in the middle, have not enough wire speed.

It might burn back on our tip a little bit.

That's another sign.

If your wire ever burns back and damages the tip, then you don't have enough wire speed,

or your drive rollers inside your machine may not be tight enough to be pushing out your wire.

Okay, well, actually, I'm going to tack it properly first.

This is going to be not enough wire speed.

So you hear that sizzle, sizzle, pop, sizzle, sizzle, sizzle, pop.

That's because the wire is going and touching the puddle, and then it's burning back because it's not feeding it at a fast enough rate.

What you want to hear in slow motion, basically, is the wire is coming down.

It touches your puddle.

It burns back, touches your puddle, burns back, touches your puddle, burns back.

And it just keeps going like zap, zap, zap, zap, zap, zap, zap, zap.

That's what makes that bacon frying sound.

So you can see this weld.

I mean, it doesn't look terrible, but it is definitely not enough wire speed.

So I'm going to turn the wire up a little here and let you listen to that.

this still may not be the perfect setting but you'll be able to hear the difference

see it's a much better sounding weld i would say this weld is a little bit on the cold side

and what i mean by that is

that the weld itself has not wet out on the edges

it has not float out a little bit flatter than what this is it's a little bit too convex

so you want your weld to be able to flatten out

or wet out and be nice

and consistent this one is a little bit on the cold side

so what i'd like to do is i'd like to hit another notch on here this is my voltage

and then proportionately you need a little bit more wire speed if you increase your voltage so

Let's give this another try.

Okay, so this one here is a much hotter weld.

You can tell that it's a little bit flatter looking.

I can tell it's a lot hotter.

You can see that the heat has gone a little bit wider there.

I think it's pretty decent, but we could probably still get it a little bit better.

What I'd like to do is I'd like to do a little bit longer weld

and just fine tune it

and I want you to really listen as to what it sounds like when you've got proper settings.

It's already sounding pretty good but I'm going to do a little bit longer weld here

and we'll really be able to see what it's like.

okay so it is pretty decently set up i don't think there's a ton of improvement

that we can make with the settings on this machine

but i want you to hear now what it sounds like

if you have too much wire speed okay

so we're going to jack this up

and it's going to kind of sound like a bit of a machine gun basically what's going to happen is

that the wire is going to be feeding faster than it can burn at the voltage

that it's set at so right now you're going to hear what it's like to have too much wire speed.

Okay, so this right here just has way too much metal now,

and you can hear that it was just trying to shove way too much metal in for how hot the voltage was,

so it couldn't burn it as fast as it was depositing it.

100

I mean, even more extreme, you'll hear it now.

101

I'll show you what happens with just way too much wire speed.

102

You know, there's just, there's so much spatter everywhere.

103

I really wanted it to start to bird nest a little bit to show you guys because I've seen some bad welds.

104

Okay, one sec.

105

I'm going to try this again.

106

Make it really horrible.

107

There we go.

108

Okay.

109

Yeah.

110

So you've seen that weld before.

111

I've seen that weld before on many occasions on a couple of cars

112

that have come in here before

113

that have been previously repaired that's just way way way too much wire speed and Maybe not enough voltage as well.

114

It just cannot handle it when you see terrible welds like that

115

It's a setting issue like that person.

116

Maybe their technique is okay

117

Maybe they're the way that they're whipping the torch around is okay, but they just have the wrong settings

118

So don't get discouraged by seeing horrible welds and think you're the worst welder.

119

It's your setting.

120

Settings are very important.

121

Let's get to another coupon here.

122

We're going to try this again.

123

Now, I'm going to show you what the different positions are.

124

So this technically is a horizontal position weld.

125

If we were welding like this, that would be a flat position.

126

If we were welding like this, that would be vertical.

127

Vertical up and down are acceptable.

128

They're both kind of for different things and then overhead welding is when you're when you're welding like this.

129

With your settings correct, overhead welding isn't as scary as it sounds really.

130

I mean you might get a little bit of sparks in your hair

131

or whatever but it welds much the same as horizontal welding.

132

So basically when you're welding with MIG, let's go over a little bit of the technique here.

133

I am holding this gun pointed in the direction of travel.

134

That's something that I guess it's up for debate but the way I was taught is that you always push the puddle.

135

You're always pushing it in the direction you're traveling.

136

The way I like to weld is that I start my puddle and I'll burn forward.

137

It's called the whip and pause technique.

138

I burn forward and I come back to fill a little bit.

139

I burn forward and I come back to fill a little bit

140

and what that almost does is it almost preheats the area

141

that you're about to fill you whip it forward

142

and then you come back and fill it up and now

143

when i'm looking at my weld i'm able to almost see

144

that when i burn forward i can come back

145

and my weld will become the same size as the previous weld deposit

146

so i can keep things pretty consistent

147

you'll get the hang of it you'll get a little bit

148

more of a signature going some guys like to do like little C's some guys like to go up

149

and down some guys like to make little circles I personally like to kind of whip

150

and pause for my technique to get my beads to look decent

151

so that's something

152

that you can play with everybody's different machine settings are the

153

most important some guys just just like to make their welds you know totally smooth and not even move

154

And you can do that too, and I don't think it's a bad weld.

155

You just have to set your machine accordingly.

156

Let's try a couple of different techniques now and just have you look at them.

157

I'm going to do this.

158

I'm going to show you kind of the different signatures that I just talked about.

159

Oh, better change my machine settings to something that isn't going to be bird poop.

160

If you've got the same machine on 10 gauge, this is the machine setting I like.

161

D and 5.

162

okay

163

so right here I'm gonna try the totally straight technique

164

I'm not gonna move around at all I'm gonna just push the puddle basically

165

I'll be at the end of the puddle and and just pushing it along totally straight at a 45 degree angle

166

So there you have it, totally straight, no moving around.

167

Weld's okay, could be a little bit hotter maybe.

168

Now I'm going to try little circles.

169

little circles does actually look pretty damn nice actually maybe i should change my technique and here's the whip and pause technique.

170

okay so now i just want to show you guys a couple of different ways to weld

171

So one of the things that if you ask a welder who's a structural steel welder, they will laugh at you for welding vertical down.

172

And vertical down is something that I guess it's controversial.

173

I don't know.

174

I use it.

175

I have a bit of a technique of my own to weld vertical down that I know works wicked.

176

The problem is that when you're welding down, it's really easy for your weld to pull up and not sink into the metal.

177

It doesn't burn in, so it's not strong.

178

And it could look like it's kind of strong,

179

but it just isn't because it's not really getting into the metal and it is gonna sound weird

180

But I push my welds down.

181

I stay ahead of the puddle and I'll push my weld down

182

Staying ahead of the puddle.

183

So I'm not actually I guess pushing it down the puddle stays up

184

I can keep the heat in the material by

185

Going downhand but pushing down if you if you try and weld downhand like this

186

it'll just drip and be disgusting and it'll it'll be a crappy welt

187

so i'm just going to show you my technique for that

188

if you feel the need to comment and tell me that i'm wrong go for it

189

okay first off i'm just going to show you me trying to make a weld doing it the way

190

that i I believe is wrong.

191

I'm going to be holding this welder up like this.

192

It's kind of natural for you to want to keep your welder pointed up

193

and drag it because you know you're fighting gravity but let's first try that.

194

The weld looks okay and I'm sure it did burn in some.

195

I do believe that it's a bit dicey to weld that way.

196

So I'm going to show you my technique now where I'm actually pushing the weld down.

197

You can tell I got tons of heat in there.

198

The legs of the weld wet right into the side.

199

It got lots of penetration.

200

I did do a little bit of whip and pause technique on that.

201

But that's welding vertical down.

202

Okay, now let's do an outside corner weld.

203

Because we're welding on the outside corner edge,

204

it will be a bit of a different heat setting as to welding on the inside of a corner

205

that reason being because you're right on the edge of the metal

206

and it accepts the heat a lot quicker I'm going to turn this down a little bit

207

and just guess at it and see how we do.

208

It's almost never that you get a weld that's perfectly flat like that.

209

So I'm going to do it this way so that you can see in more of a real world scenario.

210

You can see that one worked out quite well.

211

I did turn down my machine for that, like I said, because the heat does get absorbed by the metal much quicker

212

when you're on the edge of a piece of metal.

213

So you can see that it burned the edge of this metal away and really sunk in with the penetration.

214

So this is the whip and pause technique, where I burn forward and I come back to fill.

215

I burn forward and I come back to fill.

216

I move about an eighth of an inch

217

or three sixteenths of an inch each time that I burn forward and come back to fill.

218

I'm at a 45 degree angle this way and approximately a 35 degree angle this way.

219

Okay so now this was our whip and pause technique.

220

I'll do my next weld with a little bit of the circle technique and then we'll finish off with the C.

221

So doing little circles, it works quite well still.

222

You're definitely moving the heat around a lot.

223

When I'm doing these little circles, I find it's a little bit more difficult to be consistent,

224

but that's just me and I don't do that technique, so I find it a little bit more difficult

225

so like i said whip

226

and pause technique is is my favorite technique let's do another one here we'll try doing little c's

227

and then we'll finish off doing one just totally straight

228

and then I'll try going definitely as straight as I can

229

you know that can look nice as well okay so one thing I definitely want to go over when

230

your welding because it's really difficult for you to see through a camera I wish

231

that I had a really dark lens so

232

that we could film

233

this with the video looking like through my eyes what I

234

can see this is what I would like to explain to you is

235

that here's our world

236

and this is our puddle here this is our whip our whip our whip

237

this is our puddle what I mean by pushing the weld you would think

238

that you would want your wire speed behind it to push it.

239

That's incorrect.

240

I'm depositing my wire right here.

241

That's where you want to be.

242

You want to be ahead of the weld, pushing it along, but staying at the front of the puddle.

243

So I might burn ahead a little bit.

244

So I'll move this way and then I'll come back to fill, but I'm staying ahead of the puddle or in in the puddle

245

but at the front of it and you'll see

246

that your weld will just build up behind as you move along

247

but you do want to stay at the front of the puddle always

248

and this will keep you moving along

249

and keep you putting heat into the material as you go trying to think of what else

250

I can tell you guys for this quick little demo oh let's quickly talk about the machine itself

251

when I was talking before about your wire speed not being enough

252

and you have the wire burn back a little bit

253

that may or may not be

254

because of the wire speed adjustment on the machine something else

255

that you can look for if you don't feel like it's changing

256

when you adjust your wire speed is the tension of your drive rolls so

257

if you open up the inside of your welder

258

this one has to pop up little bit to be open there'll be a spring

259

and a nut almost on every single welder when you load your spool

260

and your wire goes in here these are the drive rollers

261

that i'm talking about so i'm just going to turn the machine on

262

so you can see them work these rollers are powered that's what's pushing

263

so if this is too loose then those rollers might slip

264

and that could give you the same symptom as not enough wire speed because it's not consistently pushing your wire out.

265

So what you would need to do there is just to tighten that up a little bit.

266

What else I can tell you about the inside of the machine is tip

267

that off and you can pull your roller out.

268

There are.. different size grooves for different thicknesses of wire.

269

This is 030 wire, but you can use 023, you can use 035, you can use 045, which will be in a much larger machine,

270

but those rollers must have the right groove for the size wire you're running.

271

I couldn't just change this to 035 wire without changing my rollers.

272

I couldn't just change this to 023 wire without changing my rollers

273

but for the most part if you are a beginner

274

and you're welding on your hot rod

275

if you've got a little bit of sheet metal work to do

276

and a little bit of structural stuff my personal suggestion is the 030 wire

277

I've welded sheet metal with it as well as welded chassis with it my other suggestion is that

278

if you are gonna do any welding on your chassis

279

you really need a 220 welder I know people can do it

280

and it can be done with a 110 volt welder my personal feeling is

281

that it's a little bit too small and a little bit too dicey for a beginner to get a strong weld

282

out of a small welder like that so make sure

283

that you are welding as hot as you can with the welder

284

that you've got for the material you're using hopefully

285

i've covered the basics for you on a little bit of mig welding

286

and the setup how to use it how to get it to work right what to do

287

if it's set up wrong thanks everybody for watching make it custom i also just want to thank everybody

288

that have supported us through our Metal Reborn premiere

289

and apologize for our technical difficulties in the first little bit of the Metal Reborn online premiere.

290

That was something we've never done before.

291

I kind of regret doing it at the exact same time as the regular premiere,

292

since we weren't on the ball enough to be able to get it fixed immediately.

293

But hopefully you guys all enjoyed the movie and it's up there for seven days.

294

So if you did get the premiere, go ahead and watch it as many times as you want for the next seven days and

295

if you were really bummed out about the technical difficulties at

296

8 p .m on Wednesday hit us up for a refund and we'll refund it.

297

Thanks everybody for watching Mega Custom.

298

We appreciate your support, your comments, your likes, everything so don't forget to like, click subscribe, hit notifications and we'll see you on the next video.

299

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
