Can argon arc welding machine be welded without argon gas?
No, if there is no argon in the cylinder, it will make squeaks and it is easy to damage the welding torch
No argon can be used as a manual arc welding machine, need to handle for welding.
No, you first need to understand the role of argon, argon is inert gas, almost without any material reaction (limit exceptions), so use it to open air, high temperature protection welding metal and welding torch tungsten pole argon arc welding is often used for sheet metal or lively, for example: very thin carbon steel, stainless steel and so on, if the AC argon arc welding, aluminum welding can Aluminum Alloy.Without argon protection, 1, the welding of high temperature metal will react with the air, blackening, porosity, welding quality is very poor. 2. The tungsten electrode of the welding gun reacts with the air and burns rapidly.Think about it, your tungsten filament bulb, if you remove the glass cover, quite in contact with the air, tungsten filament instant evaporation!
