,
tighten clockwise;
(2)
Connect the earth clamp to the work piece. Contact with the work piece must be firm contact
with clean, bare metal, with no corrosion, paint or scale at the contact point.
(3)
Connect the electrode lead to
“

,
tighten clockwise;
(4)
Each machine is equipped with a power cable should be based on the input voltage welding
power cable connected to the appropriate position, not to pick the wrong voltage;
(5)
With the corresponding input power supply terminal or socket good contact and prevent
oxidation;
(6)
With a multi meter measure the input voltage is within the fluctuation range;
(7)
The power ground is well grounded.
3.2.2 Operation for MMA Welding
(1)
According to the above method to install is correct, turn the power switch, so that the power
switch is “ON” position, then the power indicator light, the fan comes on, the device work
properly.
(2)
Select the MMA /MMAVRD function with the LIFT TIG/MMA/MMA VRD selector switch.
(3)
Set the welding current relevant to the electrode type and size being used as recommended by
the electrode manufacturer.
(4)
Set welding parameters (hot start and arc force) as required following instructions in the previous
section.
(5)
Place the electrode into the electrode holder and clamp tight.
(6)
Strike the electrode against the work piece to create and arc and hold the electrode steady to
maintain the arc.
(7)
Commence welding. If necessary, readjust the Weld Current control to obtain the welding
condition required.
(8)
After completion of welding the Power Source should be left turned ON for 2 to 3 minutes. This
allows the fan to run and cool the internal components.
(9)
Switch the ON/OFF Switch (located on the rear panel) to the OFF position.
