GENERAL DESCRIPTION
The PCT80, PCT80M and PCT80R plasma torches
have been designed for use with the Pro-Cut 55 and
Pro-Cut 80. All of the torches are single gas, air-
cooled, and use a patented HF-less torch start mech-
anism. All torches come with a quick connect adapter
for easy installation.
The hand-held torches and mechanized torches are
available with either a 25ft (7.6m) or 50ft (15.2m) cable.
Two styles of mechanized torches are available. The
robotic torch features a 8” (203mm) long, 1.625”
(41.2mm) diameter barrel. The machine torch has a
11” (279mm) long, 1.375” (34.9mm) diameter barrel
with a 32 pitch gear rack. The 32 pitch gear rack can
be easily substituted with a 24 pitch gear rack which is
included with the machine torch.
All of the K1571 plasma torches must have an elec-
trode, swirl ring, nozzle and shield cup in order to oper-
ate. These parts are used with all amperage machines
except for the nozzles. See the table in SPECIFICA-
TIONS SUMMARY for proper nozzle orifice to machine
combination.
INSTALLATION

• Only qualified personnel should perform
this installation.
• Turn the input power OFF at the discon-
nect switch or fuse box before working

A. Turn off power to the Pro-Cut at the disconnect
switch or fuse box. Do not proceed until the power
is definitely turned off.
B. To assemble a torch to the Pro-Cut:
1. Facing the front of the Pro-Cut, insert the con-
nector with the plastic retaining key in the up
position. Grasp the connector with one hand
while twisting the large lock nut clockwise onto
the threaded bulkhead with the other hand.
Tighten hand tight.
2. For mechanized torches only:
A trigger kit is included with either the machine or
robotic torch. This kit allows for triggering the
power source.
An optional Interface kit can be ordered which
adds Arc Transfer and Voltage Feedback.
C. To remove a torch from the Pro-Cut:
1. Facing the front of the Pro-Cut, grasp the con-
nector with one hand while twisting the large
lock nut at the bulkhead counter clockwise with
the other hand. Once the nut is loose, pull the
