FIRE OR EXPLOSION hazard.

D

Do not install or place unit on, over, or near
combustible surfaces.

D

Do not install unit near flammables.

D

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.

D

Use lifting eye to lift unit only, NOT running
gear, gas cylinders, or any other accessories.

D

Use equipment of adequate capacity to lift and
support unit.

D

If using lift forks to move unit, be sure forks are
long enough to extend beyond opposite side of
unit.

OVERUSE can cause OVERHEATING

D

Allow cooling period; follow rated duty cycle.

D

Reduce current or reduce duty cycle before
starting to weld again.

D

Do not block or filter airflow to unit.

STATIC (ESD) can damage PC  boards.

D

Put on grounded wrist strap BEFORE
handling boards or parts.

D

Use proper static-proof bags and boxes to
store, move, or ship PC boards.

MOVING PARTS can cause injury.

D

Keep away from moving parts.

D

Keep away from pinch points such as drive
rolls.

WELDING WIRE can cause injury.

D

Do not press gun trigger until instructed to do
so.

D

Do not point gun toward any part of the body,
other people, or any metal when threading
welding wire.

MOVING PARTS can cause injury.

D

Keep away from moving parts such as fans.

D

Keep all doors, panels, covers, and guards
closed and securely in place.

H.F. RADIATION can cause interference.

D

High-frequency (H.F.) can interfere with radio
navigation, safety services, computers, and
communications equipment.

D

Have only qualified persons familiar with
electronic equipment perform this installation.

D

The user is responsible for having a qualified electrician
promptly correct any interference problem resulting from the
installation.

D

If notified by the FCC about interference, stop using the
equipment at once.

D

Have the installation regularly checked and maintained.

D

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.

D

Electromagnetic energy can interfere with
sensitive electronic equipment such as
computers and computer-driven equipment
such as robots.

D

Be sure all equipment in the welding area is
electromagnetically compatible.

D

To reduce possible interference, keep weld cables as short as
possible, close together, and down low, such as on the floor.

D

Locate welding operation 100 meters from any sensitive elec-
tronic equipment.

D

Be sure this welding machine is installed and grounded
according to this manual.

D

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.
