SAFETY PRECAUTIONS
This section contains cautions and warnings concerning the operation of this
equipment and welding equipment in general. However, in addition to reading
this manual and before operating this or any welding equipment, users should
reference and be familiar with “ANSI-49.1 Safety in Welding and Cutting”.
This standard is published by the American National Standards Institute and the
American Welding Society.
WARNING: 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.
WARNING: This equipment is authorized to use a type of
arc starter that produces a High Frequency Radio Wave
(sometimes called HF and/or RF Starting). It can cause
interference and sometimes even damage to nearby electronic
equipment (such as computers) that are un-protected or poorly
protected against such interference.
WARNING: Magnetic Fields from High Currents can affect
pacemakers. PACEMAKER WEARERS KEEP AWAY
UNTIL CONSULTING YOUR DOCTOR.
WARNING: 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.
WARNING: Welding can cause fires or explosions. Do not
weld near FLAMMABLE or EXPLOSIVE MATERIALS.
Watch for fire. Have proper type of extinguisher in work area.
WARNING: Welding Operators should wear non-flammable
protective clothing, footwear and head gear.
