NOTE: Turn main input power to the machine OFF before performing connection procedure. Failure to do so will result in damage to the machine.

INPUT FUSE AND SUPPLY WIRE CONSIDERATIONS

Refer to the Technical Specifications at the beginning of this Installation section for recommended fuse and

wire sizes. Fuse the input circuit with the recommend- ed super lag fuse or delay type breakers (also called “inverse time” or “thermal/magnetic” circuit breakers). Choose an input and grounding wire size according to local or national electrical codes. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from welder inrush currents, even if the machine is not being used at high currents.

INPUT VOLTAGE CHANGE OVER (FOR

MULTIPLE INPUT VOLTAGE MACHINES ONLY)

Welders are shipped connected for the highest input voltage listed on the rating plate. To move this con- nection to a different input voltage, see the diagram located on the inside of the input access door. If the main reconnect switch or link position is placed in the wrong position, the welder will not produce output power.

If the Auxiliary (A) lead is placed in the wrong position, there are two possible results. If the lead is placed in a position higher than the applied line voltage, the welder may not come on at all. If the Auxiliary (A) lead is placed in a position lower than the applied line volt- age, the welder will not come on, and the two circuit breakers or fuses in the reconnect area will open. If this occurs, turn off the input voltage, properly connect the (A) lead, reset the breakers, and try again. For machines equipped with a fuse in the reconnect area, turn off the input voltage and replace the fuse with the spare fuse that is attached to the reconnect switch pin.

ELECTRODE AND WORK CABLE CONNECTIONS

Connect a work lead of sufficient size and length (Per Table 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 and wire feeder. Avoid excessive lengths and do not coil excess cable.

Minimum work and electrode cable 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)

NOTE: K1796 coaxial welding cable is recommended to reduce the cable inductance in long cable lengths. This is especially important when Pulse welding up to 350 amps.

CAUTION

When using inverter type power sources like the Power Waves, use the largest welding (electrode and work) cables that are practical. At least 2/0 (67 mm2) copper wire - even if the average output cur- rent 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 weld- ing cables are used.
