Welding controller


Constant current/constant voltage control mode: The controller can select constant current or constant voltage control mode through parameter setting, compare the sampling signal of welding current/voltage with the set value, and automatically change the trigger phase shift angle to achieve the purpose of maintaining the welding current/voltage constant.

  • DESCRIPTION
  • Introduction to 1. functions
    1. Constant current/constant voltage control mode: The controller can select constant current or constant voltage control mode through parameter setting, compare the sampling signal of welding current/voltage with the set value, and automatically change the trigger phase shift angle to achieve the purpose of maintaining the welding current/voltage constant.
    2. Current/voltage display function: the primary voltage value of the welding transformer can be directly displayed under the constant voltage control mode; the primary or secondary current value of the welding transformer can be displayed under the constant current control mode.
    3.9 welding specifications can be stored for users to call.
    4. Multi-specification welding can be performed continuously and circularly, which successfully solves the shunt problem of welding spots at different positions on the same workpiece during continuous welding, and saves the work of switching welding specifications artificially.
    5. The preheating current, welding current and tempering current can be set, which effectively solves the problem of splashing during welding and quenching of the workpiece after welding.
    6, with the current slow rise and fall function, the use of slow rise and fall function can avoid welding spatter and nugget forming bad, to obtain good physical properties.
    7. Counting function: with counting function, you can count the number of welding. Use this function to easily understand work efficiency
    8. Fault diagnosis and automatic protection function: During the working process, if the controller detects an abnormal situation, it will automatically shut down the output and give a friendly reminder.
