Model 307 Warnings
W
ARNINGS!
W ARNING : Touching energized electrical parts can cause fatal
shocks and burns. When in weld sequence the electrode and work
are electrically energized. Incorrectly installed or improperly
grounded equipment is a hazard.
W ARNING : This equipment is authorized to use a type of arc starter
that produces a High Frequency Radio Wave (sometimes called
HF or RF Starting). It can cause interference and sometimes even
damage to nearby electronic equipment (such as computers) that
are unprotected or poorly protected against such interference.
W
ARNING
: Magnetic fields from High Currents can affect pace-
makers. Pacemaker wearers should avoid being in close proximity
to welding systems.
W ARNING : Disconnect the input power to the machine before
opening or servicing. Discharge all circuits that store high voltage
such as capacitor packs. Only
QUALIFIED service personnel should
open this equipment.
