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 Figure A.2 for the location of the reconnect/input access door and related connection diagram.

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

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 in Figure A.2 and proceed according to the steps that follow for the appropriate voltage.

INPUT POWER CONNECTIONS

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

CONSIDERATIONS

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

NOTE: MACHINES ARE SHIPPED FROM FACTORY CONNECTED FOR 440 (OR 460) VOLTS

1.CONNECT L1, L2, & L3 INPUT SUPPLY LINES TO THE INPUT SIDE OF CR1 CONTACTOR AS SHOWN.

2.CONNECT LEAD MARKED TO GROUND PER NATIONAL ELECTRICAL CODE.

 

WARNING

 

Disconnect input power before inspecting

 

or servicing machine.

 

Do not operate with covers removed.

ELECTRIC

Do not touch electrically live parts.

SHOCK

Only qualified persons should install, use

CAN KILL

or service this equipment.

 

 

 

IF MACHINE CEASES TO OPERATE (NO METER, NO FAN) AND THERE IS NO OTHER KNOWN FAILURE: CHECK FUSE; REPLACE WITH A 5 AMP SLOW BLOW ONLY.

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.
