Welding Thin Metal Mig. Andor if you have a smaller MIG welder with maximum capacity of say 130-150 Amps then 08mm wire may be more suitable to the output range of your machine. Thicker welding wire also means more heat which will result in you damaging the panel you are welding.
Welding reedy metal allows you to move at a somewhat constant travel velocity with little effort. When welding thin metal the main objective is to avoid warping burn-through and excessive heat-affected zones while still ensuring the weld has enough mechanical strength for the application. Novice welders should understand that thinner wire needs to be used when MIG welding sheet metal.

Try using a piece of scrap metal the same thickness as the one you are getting ready to weld. MIG welding is one of the simplest to use for welding. You can always back up the weld area with some copper flattened 22mm pipe etc that way you dont get much burn through also handy for bridging if you do I can bridge say 5mm in thin steel with a bit of copper behind learnt that trick many years ago when repairing tears in door skins around the lock where some scroat had screw drivered the lock out on E21 BMWs you could not easily get. When it comes to MIG welding thin stainless steel it is important how the metal is transferred to the workpiece.
