Welding Sheet Metal With Stick. Stick Welding Super Thin Sheet Metal Welding Thin Metal. I use 60106011 for thin sheet metal.
For thin metal sheets that have some level of rust then you need to use grinding to eliminate the rust for MIG welding. You are basically burning the rods down on top of the metal in straight lines. Ditch a 18-inch tungsten electrode for something much smaller like 116-inch tungsten.
The real trick to weld sheet metal is to use a wire feed.
Thus spot welding diameters go from 3mm to 125mm. Stick welding sheet metal can be done by welding DC electrode negative with 20-40A which is about the the lowest amperage settings that still. We need to establish what is considered thin metal. Or most of the time there is either not enough heat to weld correctly or too much heat.
