Re: Hand Controls

I've got the tig button as well. My friend who builds cobia towers and t-tops has a wheel hand control. It's all a matter of preference.

Re: Magnesium alloy setup help

I would drill and tap it and install a helicoil. What does the bolt hold to the block? 8mm is a fairly small bolt. You might have to open up the mount hole on whatever you're mounting to use a 10mm or 12mm bolt with helicoil.

Re: Chromoly roll cage

I'm going to practice some more tonight. Been too busy with work the past few days. I'll try some more heat and better tip angle. After hammering the other test pieces to a pile of rubble I'm convinced the welds are strong. Now it's just a few more tweaks and build time. Bender is getting here today.

Re: Chromoly roll cage

I think I need to make one out of longer pipes so I can really lock it down good in the vise and beat it until it tears at the haz. Hopefully :roll:

Re: Chromoly roll cage

I was able to get enough filler in my puddle for it to be convex without having to be staying in the same spot too long. I'm going to try and break it shortly.

Re: Chromoly roll cage

So I should bevel the edge so theres a small gap at the outside of the wall but the inside has no gap? That's so the filler goes all the way to the inside edge of the wall correct? I'm going to run by airgas on a test drive and get some 3/32 wire. Try a few runs and post them up. Thanks to everyone ...

Re: Chromoly roll cage

Don't overthink it. We used to call that "nuking it out" in the navy. You're doing all the right things for good welds on chromoly. Go beat those test pieces with a sledge hammer and you'll see that those welds will be the last thing to fail. The pieces will actually be completely unrecog...

Re: Chromoly roll cage

I'm not set up for back purging yet. I'll see if I can get another tank and regulator next week. I turned the amperage down to 85 on this one. Did it in 4 sections. Opposite sides then let it cool for a few minutes the did the other 2 sections.

Re: Chromoly roll cage

I'm using 1/16" er70s rod. 3/32 2% lanthanated tip. Its shiny until I get about 75 to 80% of the way around the tube then it starts to turn light grey. When I dab the rod should I feed in more than just touching the puddle?

Chromoly roll cage

I'm a novice tig welder. Im going to build a chromoly roll cage for my utv next month so I've been practicing with my notcher and welding tubes together. My welds don't look like they have enough filler compared to Jody's on his videos. I'm not sure if I need to move faster with more heat or what. I...

Stubby kit

I have a #17 torch and am ordering the stubby kit for it. I'm also getting the #12 furick cup. My question is do I still need the adapter kit for the furick cup with the stubby kit?
