Arc welder

2 seconds after posting that I can not weld and wouldn't like to try, my brother calls me and says he's just bought an arc welder and he's been welding for a bit now.

Anyone tell me if we can wels the locost chassis with an arc welder and if not why?

It's a 110 B.T.W.

I welded my frame with an arc welder.Dunno if it's good but it looks strong enough for my go kart

from what I have seen so far, it's a problem with the joint being messy but I would clean them up with a grinder anyway so that's not an issue.

Is there any other problem? Strength of weld etc OK?

At the end of the day the difference in the strength of a weld from MIG or MMA (arc/stick welding) is nothing.

MMA produces a bit messier weld, covered in slag which you need to chip off with a hammer. Messy and takes ages. If you arent bothered about that then theres no problem with arc welding.

I am an experienced arc welder, but I had difficulty in welding the chassis to the standards needed, mainly because of the problems of using the small gauge rods needed for the job (1.6/2 mm). This may have been because of the cheap welder I was using, AC 50v. You really need a DC 80v machine for this job.

I ended up buying a cheap TIG, which I am very pleased with, it also does DC 80v Arc. The only down side is the high cost of the gas.

Good luck.

Sorry, I cannot agree, the arc weld is about the neatest you can get, if you are doing it right, the slag will curl up and fall off about 1 1/2" behind the weld pool. I do agree with RPS, the higher the OCV, the better, the old Lincoln oil cooled welders were great to weld thin metals

I aint gonna argue since i know you are a good welder from whats been said before. My welds with MMA are worse than with MIG. Maybe thats just me then

All sounds good guys thanks. I MAY have a chassis at a rediculously low price now so the welding would only be for changes!!
