3-3. Operation in MMA mode
- Switch on the welding power source. The front panel displays flashes for 5 seconds, the ma -
chine enters into the welding mode that saved in the last shutdown.
- When welding stops, Press the Welding mode switch key, the STICK indicator lights up, and it
turns into STICK mode.
- When under STICK mode, pressing theVRD/2T/4T switch key for 5 second, to selection the VRD
function. The function is enabled when the indicator lights up, and displays in multifunctional
data display. Or, the VRD function is disabled when the indicator is off.
- Multifunctional data display shows the preset current, its unit is ampere(A).
- Adjusting the Multifunctional data adjusting knob can change the welding current during
welding process, and displayed in Multifunctional data display.
- 3 seconds later after setting the welding parameters, the Multifunctional data display would
flashes for one time, which means the data has been saved. Moreover, the panel would dis -
play these data when restart the machine next time if the parameters keep unchanged.
- When perform welding, the display shows the real time welding voltage and current. 5
seconds later, it returns to the preset current state.
3-4. Operation in Lift TIG mode
- Conn ect the ground cable to the positive (+) pole.
- Use a TIG torch connected to the negative pole (-).
- Connect the gun pipeline to the appropriate substrate.
- When welding stops, press the Welding mode switch key. The TIG indicator lights up and it turns
into TIG mode..
- Adjusting the Multifunctional data adjusting knob can change the welding current during
welding process, and display in multifunctional data display.
- 3 seconds later after setting the welding parameters, the Multifunctional data display would
flashes for one time, which means the data has been saved.
- Adjust the gas flow to the regulator.
- Tap the ignition (Lift-TIG) electrode to the work piece and then lift from 2-5 mm. Then the arc is
formed and start welding.
- When perform welding, the display shows the real time welding voltage and current. 5 seconds
later, it returns to the preset current state.
3-5. Operation in MIG mode (both 100% Co
2
and mixed gas)
- Open the gas cylinder valve and adjust the flow meter to the desired position.
- When welding stops, press Welding mode button. The welding machine turn into MIG mode
and MIG indicator lights on.
- Under this mode, the Main display shows the preset voltage and preset wire speed.
- Press the Menu button for the 1st time, the Main display shows the fine adjusting range of pre
-
set welding voltage. Turn the Data adjusting knob to set the range from -20% to +20%
- Press the Menu button for the 2nd time, the Main display shows the fine adjusting range of
inductance. Turn the Data adjusting knob to set the range from -10% to +10%
- Press the switch of MIG gun. It starts wire inching. And the Main display shows “InC”. When
connected with MIG gun, press the torch switch for 5s without welding, the internal wire
spool in the machine starts to rotate and wire feeding at a high speed 11m/min for 20s. Then
it stops automatically. When release the button in 20s, wire feeding stops automatically.
