To be used on models:
This insulator kit eliminates a potential condition with the referenced power sources which could, with improper
operator set-up, lead to a serious safety issue. Inadequate clearance between certain primary and secondary
components may cause shorting of the primary voltage to the welding output of the power source. If the work
piece is not properly earth grounded as required, a potentially serious hazard could exist that could lead to
personal injury or death or other equipment damage. Follow the instructions below.

DISCONNECT primary power at wall switch, or circuit breaker,
before attempting inspection or work inside the power source.
1. Remove the power source top cover and both side panels.
2. Inspect the wiring on the rear of the voltage linkage board for wire contact with the transformer bus bar and
repair any damaged wire insulation.
3. Slip the Kydex insulator between the transformer bus bar and primary wires connected to the rear of the
voltage linkage board and secure in place using 2 plastic tie wraps supplied with the kit.
NOTE
If the distance between the transformer bus bar and the primary wiring will not allow passage of the inulator, remove the
two bolts holding the voltage linkage board and lift the board to allow passage of the insulator. Upon reassembly, insert
the 1/2" spacers between the linkage board and the "A" frame support and secure with .25 x 1" self-taping screw.
