OPERATIONAL FEATURES and CONTROLS:
UPPER CONTROL PANEL
1. ON, OFF- SWITCH
2. AMPS Meter
• Prior to STICK or TIG operation (current flow), the
meter displays preset current value (either +/- 2
amps or +/- 3% (e.g. 3 amps on 100), whichever is
greater).
amps or +/- 3% (e.g. 3 amps on 100), whichever is
greater).
• Prior to CV operation, the meter displays four dash-
es indicating AMPS unable to be preset.
• During welding, this meter displays actual average
amps.
• After welding, the meter holds the actual current
value for 5 seconds. Output adjustment while in the
"hold" period results in the "prior to operation" char-
acteristics stated above. The displays blink indicat-
ing that the machine is in the "Hold" period.

3. VOLT METER
• Prior to CV operation (current flow), the meter dis-
plays desired preset voltage value (+/- .5V).
• Prior to STICK or TIG operation, the meter displays
the Open Circuit Voltage of the Power Source or four
dashes if the output has not been turned on.

4. OUTPUT CONTROL
• Output control is conducted via a single turn poten-
tiometer.
• Adjustment is indicated by the meters as stated
above.
• When in TIG modes, this control sets the maximum
welding current. Full depression of a foot or hand

• Two status lights indicate the location of trigger con-
trol as determined by the "WELD TERMINALS" push
button.
button.
• If trigger control is local "weld terminals on", the ON
display will be lit.
• If trigger control is remote "weld terminals remotely
controlled", the REMOTE display will be lit.
• The unit will power up in "pre-determined preferred"
trigger modes.
STICK = ON
CV = REMOTE
TIG = REMOTE if remote output controls are attached
to the machine.
TIG = ON if remote output controls are not attached to
the machine.
For all versions, these trigger modes can be over-ridden
(switched) with the WELD TERMINALS push button. When
changed, the unit will power up in the configuration it was in
