Our GD series digital arc welding machine with IGBT Inverter is designed with a digital control panel, optimizing control accuracy. The IGBT welding machine is extensively applied in hardware fields, for decoration and equipment maintenance or by home DIYers. It is suitable for welding carbon steel, regular low carbon steel and stainless steel. The arc welding machine with MMA welding works well with different kinds of electrodes, especially acid and alkaline types.

Features

• Our GD series arc welding machine is compatible with two welding modes, which are Manual Metal Arc (MMA) and Tungsten Inert Gas (TIG).

• Contact-type arc ignition method is applied. In this method, a soft arc will be easily established as soon as the tungsten electrode is brought into direct contact with the workpiece to form short circuit.

• The built-in thrust regulation system is able to prevent arc extinction during the welding process and make the welding current larger as the electrode moves closer towards the workpiece, thereby eliminating welding spatter.

• The working voltage can be toggled between 115V and 230V. In case of excessively high current, overheat protection feature will be automatically enabled, thus ensuring safe and reliable operation.

  Customization
  The appearance, welding current, product manuals, package and mechanical property of our MMA welding machine can be customized according to customer requirements.

  A welder is also designed with VRD (voltage reduction device), which is featured with electric shock protection. Hence, the safety of the operator will be further guaranteed.
