Power Interface : TYPEC 5V 1A Power Interface : TYPEC 5V 1A ATTENTION!!! Due to the serious high-frequency interference of the welder, this controller is designed with an interference suppression circuit and an independent 5V isolated power supply inside! So please observe the following power plug precautions, this controller must use use 5V1A USB slow charger. Controller damage phenomenon: controller power supply is not normal, the display flashes or does not light! Repair program, replace the internal circuit board on the 5V isolated power supply module. This controller is an auxiliary welding controller for argon arc welding, which can help argon arc welding workers to easily complete the welding work and improve work efficiency This controller can accurately output the welding control time and control the consistent welding points, which can imitate cold welding and spot welding. The controller has simple wiring and convenient use, which is a good helper for the staff The controller has four working modes, single-point pulse, double-point pulse, continuous pulse, original argon arc welding It is easy to operate for novices, not easy to be welded through, and not easy to deform Single point pulse: Each time the welding button is pressed, the controller outputs a pulse Double-point pulse: Each time the welding button is pressed, the controller outputs two pulses Continuous pulse: Press and hold the welding button, the controller will continue to output pulses until the button is released Original argon arc welding: Press and hold the welding button, the controller will continue to output the start signal until the button is released Shipping list: Controller X1 Data cable X1 Socket X2 Fixing screw pack X1
