I bought an argon arc welding inverter, DC, but I can't find the place where argon is filled. Can I use the argon needle and plug it directly?
No, like carbon dioxide welding, argon protects and keeps the arc. You don't use argon to weld it all. It doesn't work well.As for the following 0.2mm only plate welding, it is obvious that the mechanical properties of the requirements are not high, you can first test, if possible, the best. But we always use protective gas for welding.
Be sure to use argon. If you don't use the seam, there will be air holes

But we always use protective gas for welding.Argon arc welding is used with inert gas (argon) as protective gas welding method of welding, welding, argon gas ejected from the nozzle in causing a dense thick gas protection layer in the welding area, which is isolated from the air in argon laminar flow, using arc electrode (tungsten pole or wire) and combustion heat to melt the workpiece is welded, and filling or filling wire, separating the metal connection as a whole, so as to obtain welding firmly.
