1. Safety Symbol Definitions
Warning! Watch Out! There are possible hazards as
shown in the adjoining symbols.
Have only trained and qualified persons install, operate,
or service this unit. Call your distributor if you do not
understand the directions. For WELDING SAFETY and
EMF information, read power source Manual.
Beware of electric shock from welding electrode or
wiring. Touching the electrode while in contact with the
work or ground can cause electric shock. Always wear
dry gloves. Keep all panels and covers closed.
Cylinders contain gas under high pressure and can ex-
plode if damaged. Never let a welding electrode touch
any cylinder. Always secure cylinder to running gear,
wall, or other stationary support.
Hot parts can cause burns. Welding makes parts very
hot let them cool before touching.
Wear safety glasses with side shields.
The RFCS (Remote Foot Control Switch) is equipped with a 14-pin plug for
connecting to the welding power source.
