WELDING OPERATION
WARNING
Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions, and parts lists.
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 dangerous.
•Keep your head out of fumes.
•Use ventilation or exhaust to remove
fumes from breathing zone.
MOVING PARTS can injure.
•Do not operate with doors open or guards off.
• Stop engine before servicing.
•Keep away from moving parts.
WELDING SPARKS can cause fire or explosion.
•Keep flammable material away.
ARC RAYS can burn.
• Wear eye, ear and body protection.
See additional warning information throughout this operator’s manual.
The RANGER 300 machines can deliver from 45 to 300 amps of constant current for AC/DC stick welding. The Ranger 300 DLX can deliver 45 to 300 amps of constant voltage current for DC semiautomatic wire feed welding. The Ranger 300 D can deliver 45 to 200 amps of constant voltage current for DC semiau- tomatic wire feed welding. AC/DC constant current TIG welding is possible across the entire range from 45 to 300 amps although 250 amps is the maximum recommended for AC TIG welding of aluminum.
Output can be adjusted by setting the POLARITY SWITCH, the OUTPUT RANGE dial, and the FINE CONTROL dial on the output control panel to the set- tings that are best for your selected welding process.
