Description
Your new inverter welder offers Stick and TIG welding processes in the same power source. These processes can be
selected with the PROCESS SELECTION BUTTON (1) on the front panel of the unit. Additionally both processes can
be run with pulsed output for better weld puddle control and out-of-position welding.
Stick Welding, “SMAW”
Both rutile and basic electrodes can be welded. Welding current is adjusted using the AMPERAGE ADJUSTMENT
KNOB (6).
TIG Welding, “GTAW”
In TIG mode, a TIG torch with a gas valve in the handle is required. The gas valve must be opened manually before
welding and closed manually when welding is completed. The arc is activated using a lift arc technique. Using the
AMPERAGE ADJUSTMENT KNOB, welding current can be adjusted.
Welder Layout and Controls
1. PROCESS SELECTION BUTTON
used to select the welding process:
2. PROCESS INDICATOR LED’s
Illuminate according to the selected welding process:
a. STICK (“SMAW”)
STICK
(“SMAW”)
DC TIG
(“GTAW”)
b. DC TIG (“GTAW”)
3. FAULT/THERMAL OVERLOAD INDICATOR LED
will be illuminated under the following conditions:
a. The duty-cycle of the machine has been exceeded or air flow is blocked. The fan will continue to run until
the machine has cooled, but output power will be disabled. Ensure that the cooling fan is running and that
there are 12 inches of clearance around all vents. When the LED turns off, welding power will be enabled
again.
b. The input voltage is outside of the acceptable range. If this indicator remains illuminated for more than 10
minutes, it is likely that there is an input voltage problem.
4. INPUT VOLTAGE INDICATOR LED
will be illuminated when input voltage to the machine is present
and the ON/OFF SWITCH (12) is in the ON position. The LED will illuminate green if connected to 240V or
white if connected to 120V.
5. AMPERAGE DISPLAY
shows the welding amperage setting (or peak amperage for pulse welding).
6. AMPERAGE ADJUSTMENT KNOB
is used to adjust welding amperage.
7. PULSE SETTINGS INDICATOR LED’s
will be illuminated to show which pulse setting is displayed on the
PULSE SETTINGS LED DISPLAY (8):
a.
Pulse (Hz)
when lit the PULSE SETTINGS ADJUSTMENT KNOB (6) adjusts the pulse welding
frequency (in Hertz or pulses per second) or turns pulse welding off. (See pulse welding section
for more detail.)
b.
Pulse (% On)
when lit the PULSE SETTINGS ADJUSTMENT KNOB (6) adjusts the percent of time the
weld output is at peak amps vs. base amps. (See pulse welding section for more detail.) Please
note this option is not available if Pulse (Hz) is set to OFF.
8. PULSE SETTINGS DISPLAY
shows the pulse settings indicated by the PULSE SETTING INDICATOR LED
(7).
9. PULSE SETTINGS ADJUSTMENT KNOB
is used to adjust the pulse settings (turn) and change
which pulse setting is being adjusted (push).
10. NEGATIVE (-) DINSE SOCKET
11. POSITIVE (+) DINSE SOCKET
12. ON/OFF SWITCH
13. INPUT POWER CABLE
