MIG welding installation
Operation method
1) After being installed according to the above method, and the switch on the back
panel being switched on, the machine is started. Open the cylinder valve, and turn
the gas check switch to the “GAS CHECK” position. Then, there will be gas output.
Adjust the
fl
ow regulator to get the proper gas
fl
ow.
2) Set the proper arc by adjusting the inductance control knob.
Turn the knob anticlockwise to get lower inductance and harder arc; turn it
clockwise to get higher inductance and softer arc. Generally, select harder arc
under lower current, while select softer arc under higher current.
3) Select proper welding voltage and welding current by adjusting the current control
knob and voltage control knob on the wire feeder.
4) Select 2T or 4T operation mode. In 2T mode, arc is ignited by pushing the gun
trigger, and arc stops by releasing the gun trigger. In 4T mode, welding can be
continued when releasing the gun trigger after arc is ignited, and at this time,
welding instructions should be set by adjusting the current control knob and
voltage control knob on the wire feeder. When pushing the gun trigger again, the
machine enters into crater welding, and at this time, welding instructions should be
set by adjusting the crater current control knob and crater voltage control knob on
the front panel of the machine. The time of crater welding is determined by the time
the gun trigger is pushed again.
5) 1 second after the arc stops, the gas supply will be cut off.
