Title: Welding
Post by: 4PLAYZJ on April 26, 2007, 08:44:13 PM

I am in the process of prepping my 8.8 for my project(brackets arrived yesterday)I am wondering if a 110v welder has enough juice to weld my brackets to the diff tubes?.  It is a miller 135.

for something with reverse stresses and what not,I wouldn't use anything smaller then a 230v welder!,we have a few 115v at work,and there pretty much just good for sheet metal.

I am not up on my welders by if you have to, you could do multiple pass to get the full weld bead.  Plus this actually strengthens the weld.

If you know what you are doing, size does not matter  :lol:

If you do not know what you are doing don't do any structural welding, period....

Some preheat, an practice passes on a test peice will tell you if you can get away with it or not.

It should be enough welder with the proper prep.

I've done it with an M135 , it turned out fine  , I'll admit   , my welding career began in 1974.

Given a choice , I'd go with a machine that has more heat though.

Use a bigger welder.

Had a member of our club weld up some diffs for his XJ with a 110V unit(D44 front and 9" rear). took it down to Moab and some of the bracketry let go on one of the trails. He had to hire a welder with a portable rig to come upto where he was and fix it. And then cause it was a trail fix it wasn't lined up quite right so he had to fix it again when he got home. This was on the front.

2 months later the rear let go on Pretty Rock......

The pattern here is that they'll be fine untill you really push it and then fail at the worst possible time!
