Spot Welders

I need to spot weld some sheetmetal in place in a pretty tight location...I don't think its really an options to try and get a drill in there and use the MIG to sort of 'spot weld' the hole - although I guess anything is possible if you try hard enough. But I've welded this kind of thing before like that, and I just can't get it strong enough given the access and my lack of skill....I was looking at using something like this:

HF also has one like it, but I am concerned with the 1/8 total maximum - it might work. And even with this set-up, not sure how big it really is, and whether it would fit....but I understand you can put long tips or whatever they are called on it. Am I missing any other options that might be better?....FWIW I am currently limited to 120V only - and as I live in Denver, CO, I've yet to find an electrician that will run a 240 to my garage (its against code or something).

 

We have one 220 plug in the basement that runs our dryer....and having a massage therapist in the house, it seems laundry is constantly being done. But if I had to....

 

you mean setting it for the thickness of the metal - kind of like setting voltage and wire feed for MIG?

If you mean cutting a hole to access the panel - that would mean cutting a hole in the rear corner panel we just did all the body work on....As for rosette welding it, well that is what I did that failed. Looks like it needed more penetration. The sad part is I welded in on the table before and installed it before the corner was done as I knew how hard it would be to access it.

I am sure for many of you, you could MIG it in location, but not sure I can...I can barely weld on a flat table - upside down in the back corner of the jeep would be tough for me - and for lack of a better way to put it, any chance to get the MIG tip in there would require 'left-handed' position if that makes sense, and no way I can get my head in there to see. I am not sure how big the spot welders are and how portable they are and how easy/difficult they are to manipulate - that's why I was asking.

 

maybe...thought about it...would have to be a pretty small bolt, and not sure about getting a drill in there....I have 90degree chuck, but its kind of bulky...guess I could buy a little battery operated unit pretty cheap that could squeeze in there. We'll see...the jeep is getting cleaned up and a couple little things done, then it gets parked for a bit while I am in MT all winter....this may all have to wait until spring unless somehow the 58 project goes fast and easy - but not counting on it.

 

Yes I have MIG, but only a couple inches to get the head in there normal to surface need to weld. And certainly I cannot get my head in there to see...maybe if I could clamp the head in place - I think Eastwood may have something like that. Also, for a sort of MIG style spot or rosette weld, I'd need to drill a bit of a hole - right angle drill chuck might work.

 

I am sure most of you could weld this as is blindfolded, but the welds I did when it was on the bench weren't good enough so worried my blind welds won't be much better.
