1. The weldingprocess is controlled by a microprocessor in closed-loop, which ensures theconstant welding current within the allowable variation range of
2. It has two control functions: constant current and constant voltage.

3. It has the functions of current step increase control, to compensate thechange of welding current density.

4. It supports 32 sets of welding specifications.

5. It can control two pressurized electromagnetic gas valves (double weldingguns).

6. Twoindependent welding specifications can be set for each welding gun, and 8specification groups can be switched through three switch combinations.

7. It has single spot welding and continuous stitch welding functions.

8. It can carryout triple-pulse welding control, especially suitable for thick plate welding.

9. It has thefunction of electrode grinding control.

10.It has thefunction of error self-inspection.
