• Premium STM microcontroller control. Accurate zero crossing detection trigger design to achieve precise control. Optocouplers isolate strong and weak electricity for more reliable operation. Compatible with thyristors 40A.
• Comes with time and current adjustment knob, turn left to decrease the value and right to increase it.
• Time and Current Digital Display: LCD digital screen displays the current set time and current. Time range 1-50 cycles, 20 milliseconds per cycle, current range 30-99%.
• Power Off Saving Function: If there is a sudden power outage or shutdown during the welding process, the welding parameters will be automatically saved. After the next startup, it can be used directly without the need for re debugging.
• Screw-free Quick Connect Terminal: The power cord and switch cable rack adopt screwless quick connection terminals for more convenient and reliable operation. Just grab the top protrusion by hand, insert the screw, then release the hand, and the wire will be pressed tightly.
