Function:

Output A: GTAW (lift arc), SMAW，GMAW, FCAW-GS, FCAW-SS, carbon arc gouging.

Output B: DC GTAW (lift arc), SMAW.

Features:

Double welding power sources, two welding outputs by one machine.

Diesel engine driven, one click operation, microcomputer monitoring, automatic protection and alarm.

Data acquisition and transmission system, supporting WIFI, 4G, etc.

High performance DSP chip is used for power source and arc control, precise control of droplet transfer, reduction of spatters, strong product consistency.

Good human-computer interactive LCD display, convenient unified regulation, and many groups of process parameters are stored for calling.

Lift arc striking arc when GTAW process is applied, which does not generate high frequency voltage and has no electromagnetic interference.

Built-in unified parameter expert database, the optimal welding parameters can be automatically matched by regulating only one parameter of welding current.

It has a wide range of welding parameters, minimal spatters, stable arc and good adaptability to the extended wire length.

Stable and reliable welding with concentrated arc energy and deep penetration can be acquired at Min. welding current 70A when GMAW process is applied.

The speed of slow wire feeding can be regulated to ensure the success rate of arc striking; the parameters of arc striking can be regulated to ensure the appropriate parameters of arc striking and to reduce defects.

The parameters of arc stopping can be regulated, with the function of removing molten ball when stopping arc so as to avoid the risk of molten ball at the end of wire and wire sticking caused by arc stopping.

Automatic welding controller interface and robot control interface are available to realize automatic welding.
