Welding For Thin Metal Sheets. Welding sheet metal with a stick welder is a bit more challenging especially when welding thin sheets of metal. Spot welding is usually used to join a panel of overlapping sheet metal parts that are usually 3mm thick.
A good heat setting for 18 6011 rods on thin material is about 80-90 amps. 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 allows to. The aim with this technique is to melt a bit of metal and then let it cool slightly before melting the next and its a handy way to avoid blowing holes.
For 332 7018s its about the same.
Everyone is different but those settings will get you in the right ballpark to weld sheet metal. Metal Inert Gas for Thin Sheets. The heat input in stick welding is generally higher than with other hand welding processes so how do you prevent blowouts and create a nice weld bead. If you dont weld sheet metal very often then you can probably get things done with030 wire as well.
