SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or electrode with skin or wet clothing.
•Insulate yourself from work and ground.
•Always wear dry insulating gloves.
FUMES AND GASES can be danger-
ous.
•Keep your head out of fumes.
• Use ventilation or exhaust to remove
fumes from breathing zone.
WELDING SPARKS can cause fire or 
explosion.
•Keep flammable material away.
•Do not weld on closed containers.
ARC RAYS can burn eyes and skin.

OPERATIONAL FEATURES and CONTROLS:
UPPER CONTROL PANEL 1. 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).
•Prior to CV operation, the meter displays four dash- es indicating
•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.
2. VOLT METER
•Prior to CV operation (current flow), the meter dis- plays desired preset voltage value
•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.
•During welding, this meter displays actual average volts.
•After welding, the meter holds the actual voltage value for 5 seconds. The displays blink indicating that the machine is in the "Hold" period.
•Output adjustment while in the "hold" period results in the "prior to operation" characteristics stated above.
3. 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 Amptrol results in the preset level of current.
4. WELD TERMINALS-REMOTE , ON
•Two status lights indicate the location of trigger con- trol as determined by the "WELD TERMINALS" push 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
STICK = ON
TIG and CV = ON or REMOTE depending if remote output controls are connected to the machine.
