What are you guys using? I have a mig and I have already did the most of the metal work on my challenger. now i know i don't need one put i still have some more work to do on the challenger then tackle my girlfriends dart which will need 2 full quarters and a trunk floor at least. So i think a spot welder would make just a little easier. i was looking at the miller 220V version http://www.millerwelds.com/products/spotwelders/msw_and_lmsw__air-cooled_/

They make a spot weld nozzle for mig welders. Not quite the same as a factory weld but works well. If you have a mig it beats buying another piece of equipment.

If you are going to buy a spot welder, get it with a timer and liquid cooling, makes nicer welds and the electrodes last longer. Tim
Hows the timer work ??? Do you clamp down and the timer auto turns on the welder then off after X amount of seconds???

how would you use this nozzel? by that i mean do you do a count, such as [pull trigger] one one thousand, two one thousand, etc. ? or does your mig have to have a "spot weld" setting that would time the weld for you ?

Yeah, how does it work? Miller discontinued theirs awhile back. The ones at HTP America aren't described well and the link there goes to replacement nozzle parts??? There are several on ebay for various mig guns (not mine).
It appears that this adapter 1. sets the wire height away from the work, 2. allows you to push down on the 2 pieces of metal, and 3. traps the shielding gas better???

Some welders have a setting for spot welds, Mine does not. I will go about 3 seconds then check my penetration, most sheet metal that is long enough. Thicker metal requires longer. It does set the wire away from your work and you need to set your speed accordingly. It does allow you to push down,but you should be as close as possible to start with. It actually allows the gas to escape.

I have used a hobart 220 unit and the Miller 220 unit in the link above. A timer is a must, as power is only applied for like .8 a second on thin sheet metal on cars. There's no way to trigger it the same each time without a timer.
The Hobart that Markz528 let me borrow had a home made timer built by him, worked great. I never did mount it in a box,put on a peice of plywood.
Then I wanted to get one of my own and found a used Miller dealon Craig's list with a foot stand and timer. The guy was asking $350 but was happy to take $300. So look for used. Buy a Hobart, Miller, not a import.
Marz528 Hobart machine with custom timer on that peice of plywood. 
The timmer right after he built it just for me to use in a hurry.
