Can I use an arc welder on low amps with 1.6 rods to tack on repair peices to car panels before MIG welding? I can't MIG weld, and have no MIG welder, but I have a friend who can MIG weld well and has one so I wondered if I can hold it on with stick weld tacks until then? The car is an Austin A35 and the panels are about 1.2mm thick (Although can't be because it was built in imperial sizing).
