Can argon arc welding machine be used as DC welding machine?
That depends on what machine, general DC arc welding is negative, when the welding torch use, positive when the ground wire. You can use it in the opposite direction, but it doesn't work well.
It's difficult to estimate.Because argon arc welding is usually less current, only a small arc is produced. The ordinary welder needs a larger current.
The DC welder can not be used as an argon arc welding machine.DC welding machine, in broad sense, as long as the output is direct current, belong to DC welder.Including two welding electrodes, hand arc welding, DC TIG welding machine, etc..Narrow sense, DC welding machine is: welding rod hand arc welding machine.Only welding rod arc welding machine, using strike arc, can be used as simple tungsten argon arc welding, the disadvantage is that the need for external gas control system. The larger the short-circuit current is, the more serious the tungsten electrode burns. The weld is easy to clamp tungsten.
