SAFETY PRECAUTION

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this installation.

•Turn off the input power to the power source at the disconnect switch or fuse box before working on this equipment. Turn off the input power to any other equipment connected to the welding system at the disconnect switch or fuse box before working on this equipment.

•Do not touch electrically hot parts.

----------------------------------------------------------------------------------------

LOCATION

•The Power Feed™ 10M Single Wire Feeder has an IP21 rating, suitable for indoor use.

•The Power Feed™ 10M Single Wire Feeder should be operated in a substantially upright position.

•Do not submerge the Power Feed™ 10M Single Wire Feeder.

•The Power Feed™ 10M Single Wire Feeder is not suitable for stacking.

Locate the Power Feed™ 10M Single Wire Feeder away from radio controlled machinery. The normal operation of the Power Feed™ 10M Single Wire Feeder may adversely affect the operation of RF con- trolled equipment, which may result in bodily injury or damage to the equipment.

FIGURE A.1

MOUNTING

Wire Drive Mounting (See Figure A.1)

The wire drive may be mounted by using the four holes on the bottom. Because the feed plate and gearbox are electrically "hot" when welding, make cer- tain the parts do not contact the any structure or per- son.

Mount the wire drive with the drive rolls in the vertical plane to prevent dirt from collecting in the wire drive. Angle the drive and feed plate to prevent sharp bends in the gun and cable and incoming wire.

WELD CAbLE SIzING

Minimum work and electrode cables sizes are as follows:

TAbLE A.1

(Current (60% Duty Cycle)	MINIMUM COPPER
	WORK CAbLE SIzE AWG
	Up To-100 Ft. Length (30 m)
400 Amps	2/0 (67 mm2)
500 Amps	3/0 (85 mm2)
600 Amps	3/0 (85 mm2)

WELD CAbLE CONNECTION

Connect a work lead of sufficient size and length (Per Table A.1) between the proper output terminal on the power source and the work. Be sure the connection to the work makes tight metal-to-metal electrical contact. To avoid interference problems with other equipment and to achieve the best possible operation, route all cables directly to the work or wire feeder. Avoid excessive lengths and do not coil excess cable.

CAUTION

When using an inverter type power source like the Power Waves, use the largest welding (electrode and work) cables that are practical. At least 2/0 copper wire - even if the average output current would not normally require it. When pulsing, the pulse current can reach very high levels. Voltage drops can become excessive, leading to poor welding characteristics, if undersized welding cables are used.
