If the transformer is overheated, the heat relay inside will open and the circuit board instructions will be displayed.
Cut out the AC relay and output welding current, and the overheat light on the front panel will illuminate. At that
time, the machine must be turned off for 15 minutes to cool the fan. When operating the machine again, the welding
output current or the working sky must be reduced.
CONNECTING THE EQUIPMENT
Steps:
1. Connect the power supply input cable of the welder to the air switch outlet port on the electrical box.
2. Connect the wire feeder cable connector to the positive output of the welding machine.
3. Connect the plug of the wire feeder control cable to the aerodynamic socket on the front panel of the
welding machine.
4. Connect the negative pole of the welder to the workpiece.
5. Connect the gas cylinder outlet tube to the gas valve set on the wire feeder and adjust.
6. Insert the torch into the outlet of the wire feed unit and hold the wire in the feeder mouth.
7. Note that the diameter of the wire must match the tip of the wire wheel and the torch. Adjust the wire
manually.
WELDING PROCESS
OPERATION IN MIG MODE:
1. Shielding gas selection
-
1) When the wire material is Fe, the shielding gas is 80% Ar+ 20% C02;
-
2) When the wire material is Si, the shielding gas is 98% Ar+ 2% C02;
-
3) When the wire material is Al, the shielding gas is 100% Ar.
NOTE
: It is necessary to replace the corresponding configuration for aluminium welding.
2. Choice of welding mode
-
1) Press the weld mode key, choose MIG mode and the MIG light will illuminate;
-
2) Press the weld mode key;
-
3) Adjustment of welding parameters;
-
4) Adjust the knob ;
-
5) Adjust the tension knob;
-
6) If the operator adjusts the wave control knob, the arc characteristics can be controlled.
OPERATION IN MMA MODE:
-
1) Press the weld mode key, choose MMA mode and the MMA light will illuminate;
-
2) Adjust the current
-
3) Adjust the welding arc power control to control the arc current.
NOTE
: The display screen must be adjusted before starting welding. This display shows the welding
current and voltage when the machine is running.
