INSTALLATION

CAUTION

Failure to follow these instructions can cause immedi- ate failure of components within the welder.

GROUND CONNECTIONS

The frame of the welder must be grounded. A ground terminal marked with the symbol is located inside the reconnect/input access door for this purpose. See your

local and national electrical codes for proper ground- ing methods. See example Figure A.2 for the location of the reconnect/input access door and your specific connection diagram.

INPUT POWER CONNECTIONS

Connect L1, L2, L3 according to the Input Supply Connection Diagram decal located on your recon- nect/input access door. See example Figure A.2.

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 recom- mended super lag fuses or delay type circuit breakers. Choose an input and grounding wire size according to local or national electrical codes. Using fuses or cir- cuit 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 RECONNECT

PROCEDURE

WARNING

Only a qualified electrician should connect the input leads to the Power Wave. Connections should be made in accordance with all local and national electrical codes and the connection diagram located on the inside of the reconnect/input access door of the machine. Failure to do so may result in bodily injury or

death.

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

Welders are shipped connected for the highest input voltage listed on the rating plate. To change this con- nection for a different input voltage, refer to reconnect instructions which follow and to the reconnect dia- gram supplied with your machine, located inside your reconnect access door. See example Figure A.2.

NOTE: Turn main input power to mthe machine OFF before perform- ing reconnect procedure. Failure to do so will result in damage to the machine. DO NOT switch the re- connect bar with machine power ON.

GRAM

Also called “inverse time” or “thermal/magnetic” circuit breakers. These breakers have a delay in tripping action that decreases as the mag- nitude of the current increases.
