WARNING
ELECTRIC SHOCK can kill.
•Do not touch electrically live parts or electrode with skin or wet cloth- ing.
•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 containers that have held combustibles.
ARC RAYS can burn.
• Wear eye, ear and body protection.
NOTE: The P.C. Board is protected by a moisture resistant coating. When the welder is operated, this coating will “bake off” of certain power resistors that normally operate at high temperatures, emitting some smoke and odor for a short time. These resistors and the P.C. Board beneath them may become blackened. This is a normal occurrence and does not damage the component or affect the machine performance.
NOTE: The cooling fan on this unit is controlled by a thermostat to operate only when it is needed.
1.To Start the Welder, move the “Power” switch to “On”. This starts the welder and lights the white pilot light on the machine control panel. This light indi- cates that the line contactor is energized).
2.Setting Welding Current
a.The “Current Control” dials on the front of the machine indicates the output current at the NEMA arc voltage. The “A” range controls the current over about 1/2 of the range of the “B” range. A toggle switch on the control panel allows selection of the desired range. The output control can be adjusted while welding.
b. Provisions for remote control are standard. A current control switch on the machine control panel labeled “Current Control at E500” or “Current Control Remote” is provided for select- ing the desired mode of operation, either at the machine or remote, Be certain the machine remote switch is in the machine position, unless a remote control is connected.
c.The “Arc Force Control”, located on the right side of the front control panel, is calibrated from one to ten. Lower settings will provide less short cir- cuit current and a softer arc. A setting that is too low may cause the electrode to stick in the pud- dle. Higher settings will provide a higher short circuit current, a more forceful arc, and possibly more spatter. For most welding, the dial should be set at approximately mid range (5 – 6). Adjustment up or down can then be made depending on the electrode, procedures, and operator preference. For most TIG welding appli- cations adjust this control to minimum for best operating characteristics.
115 VAC Duplex Receptacle (Code 10649 only)
The duplex receptacle is located near the output studs and is protected by a 15 amp circuit breaker.
115 VAC GFCI Receptacle (Codes 11042 and above) The GFCI receptacle is located near the output studs and is protected by a 15 amp circuit breaker.
