Hi I am trying to weld new body panels on my civic, I cant make the spot welds since the metal burns wright trought

these are the settings
I have a Hobart 135 with a argon bottle set at 25. I put the voltage at 1 and the wire feed at 10 just like indicated on the welder. The gas circulates at the tip and the wire is .23 guage.

How can I get cooler slower welds so the panels wont warp or burn.

 

dont use gas it makes it burn hotter turn your speed up and the heat down and that should do it for you

 

I would say less gas (abouty 23) and turn the speed down to 7..

How close are you holding the gun and how long are you holding the trigger?

 

you will need to use a "tack" method to weld it. make tacks every 2 inches along the seam. then cool the welds with a damp cloth. again, make tacks directly to the right of the first tacks every 2 inches. keep doing this until the tacks are a continous weld. KEEP THE METAL COOL! burning through will be the least of your worries if you warp the **** out of the pannel. i would say 18-22psi on the gas. if its still burning though maby try speeding up the wire a little. i've welded in panels with a flux core welder and .35 wire before so it should be cake with the gas mig setup. be sure the metal has a bare finish to it and your ground is good and the piece your welding in fits PERFECTLY.

to finish the welds get a grinder with a flexible 40 grit sanding disc. grind the welds extreamly slowly constantly cooling the metal with a damp cloth as you go. if you are setting in a piece to weld it is better to have the metal slightly too low as uposed to having too high and creating a high spot. high spots suck to hide and the peice will never be quite true. grind the welds down slightly lower than the metals surface and use a little filler to build it back up to sand perfectly.

hope this helps!
