The PT-27 Replacement

disigned to feed through

the insulating Handle and

connect at the back.

DO NOT Make Any

The PT-27 Head assy. P/N 21610 must be properly wired to insure that damage does not occur during arc

starts. Be sure that the long lead supplied with the head is routed through the insulating handle to the rear

and all connections are made as shown below.

Connecting the PT-27 torch head lead in front of the insulating handle will expose the connection to

extreme high frequency pulse during arc start, sufficient to destroy the connection!
