I've done some butt welding with MIG, just keep the wire over close to the weld puddle.

In this video below, Jody shows a weld on a corner joint, downhill, at 4:00 and 4:30 minutes into the clip where he uses the puddle to MIG with a gap.

Side note: Even though my downhill welds were always beautiful, I'd always been told, "You can't weld downhill because it will introduce cracks into the weld." He does it in the video below, though. Was I told wrong?

Thanks for the info....

Hey Oleg, what's the hold up... you want people to subscribe to a relatively empty youtube channel ?... what's the point. Videos sell welders. I bought mine after seeing a video of it.

+1. I like videos!

I totally agree. When I look at welders I look for everyy video out there of that product or a close product to compare with. The videos out there of the powerarc200 sold me on it. And other everlast welders with the arc used in videos seeing how good they really do work.

It takes time for sure, and I have a 205P powerultra to video, but not the good stuff.

Maybe if we can get the 250 ext up and going, then I could get one out of it before he ships it out to someone. Point is, I get the cheap stuff to video.

No, it won't introduce cracks in the weld, or nearly every small trailer, and cargo trailer manufacturer in this country is in deep doo -doo. Not properly done, it can have issues such as slag entrapment or incomplete fusion, which would cause cracking at the weak points, but you are not "introducing" cracks to the weld necessarily, other than for incomplete fusion.

Thanks for the follow-up, Mark.
