SECTION 3
3.1 General
INSTALLATION

completely assembled with 250A consumables.
Pilot arc cable and hoses may have to be
assembled.

NOTE: It will be necessary to slide the outer sleeve
of the torch bundle toward the power source to
expose the pilot arc connection.
2. Connect the cooling water IN (left-hand threads)
and cooling water OUT (right-hand threads)
hoses to torch body. A 1/2" open end wrench
is required.
NOTE: Coolant hoses (IN and OUT) are the same
part number. The assembly requires two. The
hoses are designed with a right hand d threaded nut
on one end and a left hand threaded nut on the
other. Reverse one hose end-for
for-end to make the
proper connections.
NOTE: The cooling water tubes are shorter than the
gas tubes.
3. Connect gas fittings. To prevent cross
attachment, the cut gas fitting is smaller in
diameter than the shield gas fitting. 7/16" and
1/2" wrenches are needed.
NOTE: It is possible to cross one of the water
connections with one of the gas connections. Each
water hose has a cable inside for carrying voltage.
4. Insert exposed pilot arc cable into the copper
high frequency connector (H.F.). Tighten set
screws using a 1/16" internal hex wrench. (i.e.
Allen Wrench)
