anyone have input on one of these? I just think it may be better for a lot of the welds required for replacement of 1/4 panel, tail panel etc.

not enough amprage for good welding. sutible for building toys and such.

i did a search on spot welders & u guys already went over this. sorry. good info on previous threads though.

i purchased a cheap spot welder like the link below. welded 2 pieces of 1/16 sheetmetal together. you absolutely cannot take them apart with tearing them. the weld is stronger than the surrounding base metal.

i tried it on 2 1/8 pieces. it will hold but can be driven apart with a hammer and wedge,without tearing the beasemetal.so i have found the limitation.

i can see it working fine with two pieces.but if the situation calls for 3 pieces sandwitched together,them im not sure.one downfall is the location of the welds.you are very limited in positions.

I own a company that makes the electronic controls for industrial resistance welders (spot welders). The problem is more likely getting enough force (pinching pressure) than in getting enough amperage. If you have poor fit up of the two parts, you probably can't get enough force to get a good weld.

BTW it takes the same amperage to weld three components as it does to weld two.

Well guys i bought a spot welder from Harbor Freight and tested it on some 22ga metal and it does a pretty good job. I realize the sheetmetal on the car will be a little thicker but i think it will do a sufficient job. At least good enough to be able to drive the car to a REAL welder!
