im about to so some shaving of my engine bay and some of the spots are pretty thin metal.. i really don't want to mess it up and burn through.. what would be a good setting for something like that

its just a basic wire feed welder and we use gas.. also maybe there i a better type of wire for something like that?

 

 

Use thinner wire, .030 or .035 will do, pull the trigger then stop, basically spot weld.

 

yea we have .35 wire right now

what kind of speed and heat settings work for thinner stuff?

 

How thin ? Usually the lowest setting

 

engine bay of a civic.. the side metal is pretty thin

 

This is a great write up. Thank you. But the pictures arent loading for me.

 

magnetic copper plates... the heavier the better. keeps it from blowing thru, but dont try using pennies. Dissasterous results!!

 

Use thin wire it will help. Best will be to have access to a TIG welder

 

Copper is non-ferrous....

But you have the right idea. Also an aluminum backer will work.

Good stuff. I was looking for some info on this myself. Not to mention the rusted through holes in the floorboard I need to find a way to fix.
