ELECTRICAL INSTALLATION

WARNING

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts such as output terminals or internal wiring.

•When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.

•Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.

•Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

•Only qualified personnel should perform this installation.

Work Cable

Connect a work lead of sufficient size and length (per the following table) between the proper output termi- nal on the power source and the work. Be sure the connection to the work makes tight metal-to-metal electrical contact.

Input Cable: STT-10 Control to Power Source

Available Cable Assemblies:

K1758 Consists of an 8-conductor control cable with a 14-pin plug, a 6-conductor control cable with a 10- pin plug, and an electrode cable with Twist-Mate™ connector. It is rated at 300 amps, 60% duty cycle and is available in lengths of 10 ft.(3 m), 25 ft.(7.6 m), and 50 ft.(15 m).

With input power disconnected from the power source, install the input cable per the following:

1)Connect the end of the control cable with the 14- pin cable plug to the mating receptacle on the power source. Connect the 10-pin cable plug to the mating receptacle on the power source.

2)Connect the electrode lead to the power source output terminal of the desired polarity.

3)Connect the 8-socket plug of the control cable to the mating receptacle on the bottom of the STT-10 control box. Connect the 6-rocket plug of the con- trol cable to the mating receptacle on the bottom of the STT-10 control box.

4)Slip the current sensor cover off enough to expose the input connector stud. Connect the electrode cable from the power source to this stud with the nut provided, then reclose the current sensor cover.
