Gouging With The Pt-38; Installing Consumables - ESAB PT-38 Manuel D'instruction

4.3 Gouging with the PT-38
PC-1300/1600: Insert high current gas baffle, electrode, 90 amp gouge nozzle, and 90 amp gouging heatshield assembly.
Operating parameters are 60 - 80 psi (4.1 - 5.5 bar) and 70 - 90 amps. Air pressure and current can be varied within these
ranges to produce desired metal removal rate and groove profile.
PC-900: Insert standard gas baffle, electrode, 60 amp gouge nozzle, and 60 amp gouging heatshield assembly. Operating
parameters are 60 - 80 psi (4.1 - 5.5 bar) and 40 - 60 amps. Air pressure and current can be varied within these ranges to
produce desired metal removal rate and groove profile.
4.4 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.
A. Tighten electrode and retaining/shield cup fully at each consumable change or inspection.
B. Check consumable tightness at beginning of each work period, even if everything was working normally at the end of
the previous period.
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.
Firm tightening of the electrode by hand is
sufficient, the use of tools such as wrench-
es or pliers is not required or
recommended.
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.
