Can the DC welder be used as an argon arc welding machine?
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.
The DC welding machine can be used as an argon arc welding machine in theory, but the current required by argon arc welding is much larger than that of general welding, and many DC welding machines can not adapt to them.DC welding machine is not necessarily inverter welding machine, inverter welding machine is not all DC welding machine.
As long as the inverter direct current welding machine can use simple argon arc, friction arc, economical and durable pipe operation more. The DC welder also has screw type silicon controlled rectifier. Are hundreds of KG one, power consumption, mobile inconvenience.
