Hi all,
I just bought a Suzuki Sierra and found the passenger side floor pan has rusted through in some spots so I was thinking of having a go with my MIG but I'm basically new to welding and I'm not 100% confident on a few things.
It's a 120/60amp gasless mig (cheap chinese generic model off ebay
) im not sure if this can weld thin sheet metal though because I used it last week fitting an exhaust to my car and it kept blowing holes through the metal instead of welding it.
But I did manage to get a very clean weld between the extractors/cat converter somehow.. I was amazed at how good it was. I moved on to install the extractors to the motor and weld up the exhaust to the cat converter with newfound confidence but these joins turned out awful and this is where the holes blew through and created awful welds, basically and it surprised me how I got such a good weld on the first join compared to all the others.
I wasn't blowing holes in the first weld I can only think it was because I overlapped the pipe making the join thicker and much more snug (hammered on and unable to remove snug). The other joins where identical diameter and I had to clamp them together and weld the gap inbetween which resulted in blown holes. Isn't it possible to weld gaps with a welder or is my welder simply too powerful and I need a new one? I only had it on the 60amp setting and I'm worried about doing the floor pan in the suzuki now as it's basically sheet metal thickness (which is even thinner that my exhaust)
