Adjust the distance between. Rotating the adjustment screw lever on the left extreme jaw spacing should be two pieces of total length and squeeze poor. When the joystick is correct when the jaws should be the distance between the total length of the two pieces and 2 ~ 3mm, the original position before welding.
Adjust the short-circuit limit switch of the welding machine so that it can automatically cut off the power supply when the welding ends (reaches the predetermined extrusion).
According to the shape of the weld, adjust the jaw and on the same level, the chin, and then clamp the welding. In order to prevent overheating of the weld, the welding test accumulates the adjustment series and selects the appropriate secondary voltage. Flash butt welding, should handle higher secondary voltages.
