5-3. Operation(STICK)
USE SINGLE PHASE 115V/208/230V POWER SUPPLY.
5-3.1.DCEP (electrode connect to positive output) is most common used connection
for STICK welding. In some case, DCEN or AC connection is required
according to the specification of the electrode used.
5-3.2.Connect up the electrode holder, earth lead to power source according to
section 4.3: STICK welding connection diagram, make sure connections are
firm and reliable.
5-3.3.Switch on the power source. Select STICK mode with the process selection
control.
5-3.4.Set Welding parameters to desired value, refer to section 5-6: Welding
parameter selection chart and section 4-1: front panel layout and description.
5-3.5.Press down parameter adjust knob and hold for 2-3 seconds, the VRD light
will turn on. Dial the knob to choose VRD on or off, and press the knob again to
confirm.
VRD stands for “voltage reduction devices”. When VRD is turned on the
maximum unloaded open circuit voltage across the output terminals of the
welder reduces to a safe voltage (15 VDC). VRD will sense when the electrode
contact with work piece and turn the welder to full output to strike the arc
. When
the electrode is removed from the workpiece then the VRD will turn the output
of the welder back to a reduced output state.
5-3.6.Drag electrode across workpiece like striking a match; lift electrode slightly
after touching work. If arc goes out electrode was lifted too high. If electrode
sticks to workpiece, use a quick twist to free it.
5-3.7.At the end, turn off welding power source and wall switch.
5-4. Operate with remote current control device connected( TIG only)
The machine can connect to foot pedal (part no. 07002510) or torch with remote
current control through 12pin control receptacle at the front panel. Machine will
