Repositioning Torch Switch

In some applications it is more convenient for the troch switch to be positioned 180 degrees from current configuration.
To reposition the switch on the torch, slide the flex support back, remove the tape securing the spliced leads to the power
cable, reposition switch, retape the leads, and pull the flex support back in place. See Figure 4-1.

Before any maintenance is attempted on this torch, make sure the POWER SWITCH
on the power source is in the OFF position and the PRIMARY INPUT POWER is
DEENERGIZED.
Note
BE SURE to loosen fittings using 2 wrenches during disassembly. Failure to do so
could result in serious injury to the operator.
DO NOT remove the white tape that forms a band around the power cable at each
end. The sheath is taped to the cable in front of the band which acts as a shoulder
to prevent the sheath from sliding back on the cable. Replacement cables have
this tape in place.
If the switch leads are to be replaced, replace with 16 AWG STRANDED COPPER,
600- VOLT, 90 C (194 F) INSULATED WIRE.
