ELECTRIC AND
MAGNETIC FIELDS
May Be Dangerous
1. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields
(EMF). Welding current creates EMF fields
around welding cables and welding machines.
2. EMF fields may interfere with some
pacemakers, and welders having a pacemaker
should consult their physician before welding.
3. Exposure to EMF fields in welding may have
other health effects which are now not known.
4. All welders should use the following
procedures in order to minimize exposure to
EMF fields from the welding circuit:
5. Route the electrode and work cables together -
Secure them with tape when possible.
6. Never coil the electrode lead around your
body.
7. Do not place your body between the electrode
and work cables. If the electrode cable is on
your right side, the work cable should also be
on your right side.
8. Connect the work cable to the workpiece as
close as possible to the area being welded.
9. Do not work next to welding power source.
FALLING UNIT Can
Cause Injury
1. Lift unit with handle on top of case.
2. Use handcart or similar device of adequate
capacity.
3. If using a fork lift vehicle, place and secure
unit on a proper skid before transporting.
IMPORTANT SAFETY INSTRUCTIONS
FOR ELECTRICALLY
Powered Equipment
1. Turn off input power using the disconnect
switch at the fuse box before working on the
equipment.
2. Install equipment in accordance with the
countries National Electrical Code, all local
codes and the manufacturer's
recommendations.
3. Ground the equipment in accordance with the
countries National Electrical Code and the
manufacturer's recommendations.
HOT PARTS Can
Cause Severe Burns
1. Do not touch hot parts bare handed.
2. Allow cooling period before working on
welding gun or torch.
FIRE or EXPLOSION
Hazard
1. Do not place unit on, over, or near
combustible surfaces.
2. Do not service unit near flammables.
STATIC Can Damage
PC Boards
1. Put on grounded wrist strap BEFORE handling
boards or parts.
2. Use proper static-proof bags and boxes to
store, move, or ship PC boards.
