DUse only genuine replacement parts from the manufacturer.

DPerform maintenance and service according to the Owner’s Manuals, industry standards, and national, state, and local codes.

OVERUSE can cause OVERHEATING

D Allow cooling period; follow rated duty cycle.

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

DDo not block or filter airflow to unit.

FLYING SPARKS can injure.

D Wear a face shield to protect eyes and face.

D Shape tungsten electrode only on grinder with proper guards in a safe location wearing proper face, hand, and body protection.

DSparks can cause fires — keep flammables away.

STATIC (ESD) can damage PC boards.

DPut 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 injure.

DKeep away from moving parts.

DKeep away from pinch points such as drive rolls.

WELDING WIRE can injure.

DDo not press gun trigger until instructed to do so.

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

H.F. RADIATION can cause interference.

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

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

DThe user is responsible for having a qualified electrician prompt- ly correct any interference problem resulting from the installa- tion.

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

DHave the installation regularly checked and maintained.

DKeep 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.

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

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

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

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

DIf 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.
