Introduction - Lincoln Electric POWERTEC 205C Series Operator's Manual

WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION: Remove fire hazards from the welding area
and have a fire extinguisher readily available. Welding sparks and hot materials from the welding
process can easily go through small cracks and openings to adjacent areas. Do not weld on any tanks,
drums, containers, or material until the proper steps have been taken to insure that no flammable or
toxic vapors will be present. Never operate this equipment when flammable gases, vapors or liquid
combustibles are present.
WELDED MATERIALS CAN BURN: Welding generates a large amount of heat. Hot surfaces and
materials in work area can cause serious burns. Use gloves and pliers when touching or moving
materials in the work area.
CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the correct
shielding gas for the process used and properly operating regulators designed for the gas and pressure
used. Always keep cylinders in an upright position securely chained to a fixed support. Do not move or
transport gas cylinders with the protection cap removed. Do not allow the electrode, electrode holder,
work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders must be located
away from areas where they may be subjected to physical damage or the welding process including
sparks and heat sources.
MOVING PARTS ARE DANGEROUS: There are moving mechanical parts in this machine, which can
cause serious injury. Keep your hands, body and clothing away from those parts during machine
starting, operating and servicing.
SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in an
environment with increased hazard of electric shock.
The manufacturer reserves the right to make changes and/or improvements in design without upgrade at the same time
