Cutting with the PT-37

Use the following procedures to cut with the PT-37 torch.
4.1

Installing Consumables

Tests have shown that with proper use of the torch within rated operating conditions (especially arc current and
gas flow rate), the torch consumable parts do not become loose if they are firmly installed. Torch damage and
overheating can be caused by loose parts.
1. Make sure that the wall disconnect switch is off.
2. Tighten electrode and retaining/shield cup fully at each consumable change or inspection.
3. Check consumable tightness at beginning of each work period, even if everything was working nor-
mally at the end of the previous period.
Note:
Ensure that the electrode/torch body seat
and piston are clean and free of dust or
dirt. Debris may prevent mating surfaces
from having solid contact.
Note:
Firm tightening of the electrode by
hand is sufficient, the use of tools such as
wrenches or pliers is not required or
recommended.
Note:
Torch damage and overheating can be
caused by loose parts. Arc tracking indi-
cates loose parts. Make sure retaining cup
is tightened fully. Parts damaged by arcing
will cause destruction of torch and must
be replaced.
4. Make sure that the wall disconnect switch is on. Turn on the Power Switch to the cutting power source
console.
5. Set Pressure Regulator to 80 psig (5.5 bar).
6. Adjust torch standoff to required initial / piercing height.
DO NOT USE OxYgEN WITh ThIS TORCh! A hAZARDOUS FIRE MAY
RESULT.
