5.0 STICK ELECTRODE WELDING (SMAW)

5.1 GETTING READY FOR STICK ELECTRODE WELDING (SMAW).

• Select the Stick function (SMAW) with the Selector Switch (6) on the front panel.

• Check the electrode packaging to determine the recommended polarity and connect the Electrode

holder and ground clamp to the plus and minus Dinse sockets accordingly.

• Switch the unit ON thru the ON/OFF switch (13).

• Set the welding current with the Left Knob (8) on the front panel and the strike over-current value

of the electric arc (Hot Start) with the Right Knob (7).

Adjustable Welding current:

115V input voltage: Min 20Amp – Max 100 Amp

230V input voltage: Min 20Amp – Max 170 Amp

6.1 SETTING UP THE EQUIPMENT FOR TIG WELDING

• Select the TIG function on the control panel with knob (6).

• Connect the TIG torch cable to the negative dinse socket (9) of the welder.

• Connect the ground cable connector to the positive dinse socket (10) of the welder.

• Connect the TIG torch gas line to the gas regulator, ARGON GAS ONLY

• Switch the unit ON thru the ON/OFF switch (13).

The gas flow is manually controlled with the knob on the TIG torch. Use inert gas

(argon ) only.

CLOSE THE GAS VALVE ON THE TORCH HANDLE. Turn on gas at the gas regulator,

then open the valve on the torch handle and check for gas flow.

6.2 STARTING THE ARC BY CONTACT (LIFT ARC)

• Fix the tungsten electrode so that it protrudes approximately 4-5mm from the torch nozzle.

• Set the welding current with the Left Knob (8).

• Position the torch at a distance of 3-4mm so with the nozzle in contact with the work piece at a 45

degree angle.

• With a rapid movement short - circuit the tungsten electrode and go back to a distance of 3-4

mm. Advance the torch maintaining the same distance from the work piece. To stop welding, sim-

ply remove the torch from the work piece.

REMEMBER to turn OFF the gas immediately after you finish welding.
