SECTION 4
5. The power cable and switch leads in the service line should be inspected
periodically. If there are any cuts through the protective sheath or if gas leaks
are noted, replace the damaged component.
By following Steps 1, 2, and 3 in Fig. 4 the service line can be removed from the
torch. To disassemble the service line, lay the line out straight, remove the tape
from around the switch lead splices, and free the switch by cutting the leads close
to the splices. Replacement switches have extra long leads to make up for any
loss due to cutting. Remove the rubber boot from the inlet end of the cable and
remove the tape that secures the sheath at each end. Pull the sheath off the cable
(over small fitting at torch end). Note that the switch leads wrapped around the
power cable are secured with tape several places along the cable. The leads,
switch cord plug, and strain relief can now be removed. 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. Reassemble in reverse order.
6. 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.
NOTE: A thin film of silicone lubricant P/N 0558000443 (17672), supplied with
the spare parts kit, applied inside of the flex support will ease the
assembly of this part.
