Additional precautions for installation, operation, and maintenance
Do not install or place unit on, over, or near combustible surfaces. Do not install unit near flammables. Do not
overload building wiring − be sure power supply system is properly sized, rated, and protected to handle this
unit.
FALLING UNIT can cause injury.
Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories. Use equipment of
adequate capacity to lift and support unit. If using lift forks to move unit, be sure forks are long enough to
extend beyond opposite side of unit.
OVERUSE can cause OVERHEATING
Allow cooling period; follow rated duty cycle. Reduce current or reduce duty cycle before starting to weld
again. Do not block or filter airflow to unit.
STATIC (ESD) can damage PC boards.
Put on grounded wrist strap BEFORE handling boards or parts. Use proper static-proof bags and boxes to
store, move, or ship PC boards.
MOVING PARTS can cause injury.
Keep away from moving parts. Keep away from pinch points such as drive rolls.
WELDING WIRE can cause injury.
Do not press gun trigger until instructed to do so. Do not point gun toward any part of the body, other people,
or any metal when threading welding wire.
MOVING PARTS can cause injury.
Keep away from moving parts such as fans. Keep all doors, panels, covers, and guards closed and securely
in place.
H.F. RADIATION can cause interference.
High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications
equipment. Have only qualified persons familiar with electronic equipment perform this installation.
The user is responsible for having a qualified electrician promptly correct any interference problem resulting
from the installation.
If notified about interference, stop using the equipment at once. Have the installation regularly checked and
maintained. Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting,
and use grounding and shielding to minimize the possibility of interference.
ARC WELDING can cause interference.
Electromagnetic energy can interfere with sensitive electronic equipment such as computers and computer-
driven equipment such as robots.
Be sure all equipment in the welding area is electromagnetically compatible.
To reduce possible interference, keep weld cables as short as possible, close together, and down low, such
as on the floor.
Locate welding operation 100 meters from any sensitive electronic equipment.
Be sure this welding machine is installed and grounded according to this manual.
If interference still occurs, the user must take extra measures such as moving the welding machine, using
shielded cables, using line filters, or shielding the work area.
