How To MIG Weld Skinny Automotive Sheet Steel for Novices

No gloves?

Great video, thanks

Horrible video,you have no fab or welding skills.
You welded a flat cap pc on to a rounded fender without even putting putting an arc in the cap pc.
Why would you make a video to show others how to do something you don't even know how to do yourself?

Thank you so much for this video. I've seen other videos but not as detailed as this one. My wife bought me a Mig 140. I've never weld before but I guess she remembered me saying I would like to learn how to weld so I could repair my own exhaust when we were at the muffler shop being im a DYier. I'm a quick learner but to learn things right I needed this video which explained everything. I needed this video. Know i will need some practice of course. Can't wait to get started.

Good tips, Welding upside down to old metal is another thing altogether on an old car 😂

Great info .. I’m amateur doing a chop on an antique 1937 Chevy … still so may times I burn through, gaps ugly .. etc

I usually run my wire the other way around. From the bottom out. Not the top out like yours. Plus for sheet metal I also use 0.030. 0.023 would be even better for sheet metal. I've been welding for over 40 years. Heavy metal, 2' to sheet metal. You do as you wish though.

I dont have a compressor, but i have the fan. When my ordered welder will appear, i will practice as you shown in this video. Thank you very much!!!

You’re wasting so much gas with it way up there only need just enough to shield the weld not pollute the world with gas .6 .8 wire only 😂😂😂 learn on car ffs get a rusty Datsun Ute or something

I really don’t like videos without narration. And though I feel I don’t want to give those kind of silliness any time of the day. I’ve watched it a at too long. Two thumbs down. Not for the content. For no narration

Why cool with air instead of a damp rag.

Just before you pull that trigger, is your wire touching the surface, or do you hover above a millineter or so?????

Your wire spool is feeding from the top, rotating clockwise. Northern hemisphere correct rotation is counter clockwise. It also feeds wire straight into the feed roller assembly, without bending the wire as it enters said assembly, or causing wire drag at assembly entry point.
Also why do you use 70S-3? Lots of guys use 70S-6 and other wires too. If there's crud on body panels, S-6 might be the call. If all is clean, S-3 is OK.
I especially question the wire diameter of .035, as it takes more energy to fuse the sample material. This, in turn, heats the materials more quickly — especially if performing these maneuvers after lunch. Nothing warps a panel quicker.
Why to choose machine settings as shown? Now, I know those settings are just to save electricity, but some guy just starting out might have a question.
Vernier caliper read about .O52, I thought. That's much thicker than 18 guage. Perhaps you should turn the machine back up?
What gas was used? Regular? Or premium? And what is See — 25 anyway?
I have-tuh stop. Too painful. But know your subject before you attempt to teach.

Great video, thank you
