Safety Depends on You
Huayuan arc welding and cutting equipment is designed and built with safety in mind. However, your
overall safety can be increased by proper installation ... and thoughtful operation on your part.
DO NOT INSTALL, OPERATE OR REPAIR THIS EQUIPMENT WITHOUT READING THIS
MANUAL AND THE SAFETY PRECAUTIONS CONTAINED THROUGHOUT.
Attention
● ARC WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM
POSSIBLE SERIOUS INJURY OR DEATH.
●
BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR
PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
●ARC RAYS can burn.
a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the
arc when welding or observing open arc welding..
b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your
helpers from the arc rays.
c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch
the arc nor expose themselves to the arc rays or to hot spatter or metal.
●ELECTRIC SHOCK can kill.
a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch
these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough
to cover your full area of physical contact with work and ground.
c. Always be sure the work cable makes a good electrical connection with the metal being welded. The
connection should be as close as possible to the area being welded.
d. Ground the work or metal to be welded to a good electrical (earth) ground.
e. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating
condition. Replace damaged insulation.
f. Never dip the electrode in water for cooling.
●FUMES AND GASES can be dangerous.
a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.
When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone.
b. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or
spraying operations. The heat and rays of the arc can react with solvent vapors to form phosgene, a highly
toxic gas, and other irritating products.
c. Read and understand the manufacturer’s instructions for this equipment and the consumables to be used.
●FOR ELECTRICALLY powered equipment.
a. Turn off input power using the disconnect switch at the fuse box before working on the equipment.
b. Install equipment in accordance with the National Electrical Code, all local codes and the manufacturer’s
recommendations.
c. Ground the equipment in accordance with the National Electrical Code and the manufacturer’s
recommendations.
●WELDING SPARKS can cause fire or explosion.
