Re: welding question
sorry popeyestruck, I read the part where you said you welded in cab corners but my brain took me to a place where the metal was rusty and had pinholes. thanks LG for the snap back to the actual scenario and question.
do like LG says and weld the pinholes you can get to and recheck with the light. if mig welding ensure the wire in the gun has a chisel tip on it (freshly cut off after each weld) so you get as clean a weld start up as you can. of course the metal also needs to be clean both sides as LG says. sometimes its a good idea to try the gun, without welding, so you can ensure you are getting gas flow right away when the trigger is pulled. also, set the contact tip and gas cup so the contact tip isn't stuck way back up inside the gas cup otherwise it is like having too much stick out and the weld is affected.
