Welding methods

MIG Welding/TIG Welding/ARC Welding/Plasma CUT (PILOT)


Performance characteristics

✱ MCU control system, reacts immediately to all changes

✱ Adopt IGBT high-frequency inverter technology.

✱ High-definition digital display screen, simple and convenient operation.

✱ One machine with multiple functions can meet all welding methods and metal cutting tasks.

✱ Nine sets of channel storage capacity.

✱ Pulse argon arc welding can obtain a large penetration depth under a lower heat input, which can reduce the heat-affected zone and reduce the tendency of welding deformation and cracks.

✱ Provide MMA welding thrust function and hot start function.

✱ It can weld a variety of materials, including stainless steel, high-strength steel, aluminum alloy, magnesium alloy and titanium alloy.

✱ The device works with a high-frequency ignition with no contact to the workpiece (advantage of precise and faster cut)

✱ Cutting current - stepless adjustment from 20 to 40 A

✱ Smart protection: overvoltage, overcurrent, overheating if the above Problems occur, the front warning lamp is on and the output current is switched off. It leads to self-protection and extends the useful life cycle.
