2.0 Plumbing Box Description
The PCC-14 Plumbing Box is a Plasmarc Cutting Control used to connect PT-36R, PT-26,
PT-19XL, PT-19XLS, PT-600 or PT-251 torches to a remotely located ESP-150, ESP-200, or
Deucepack system . The PCC-14 includes high frequency starting circuits to eliminate
starting problems with long torches and to minimize high frequency interference with
other customer systems .

Specifications

Weight:
41lbs . (18 .6 kg)
Plasma and Start gases:
The PCC-14 may be used with O2, N2, Air, or H-35 (35% H2/65% Ar) with a maximum input pressure of 110 psig (7 .6 bar) .
It is recommended, but not required, that N2 be used as the start gas when using H-35 . The flow rate of gas will depend on
the pressure set, the torch connected to the plumbing box, and the parts installed in the torch . Without a torch attached,
the maximum flow rate for these gases at 100 psig (6 .9 bar) is about 1000 scfh (28 .3 cu-m/h) . The minimum acceptable
pressure for the start gas is 19 psig (1 .3 bar); for the plasma gas it is 24 psig (1 .7 bar) . Below these pressures the pressure
switches may not be satisfied .
Shield gases:
The PCC-14 may be used with Air, N2, Ar, or CO2 . The maximum pressure is 110 psig (7 .6 bar) . This will result in a flow of
250scfh (7 .1 cu-m/h) N2 . See Graph 2-1 . There is no pressure interlock on the shield gas .
coolant:
The PCC-14 is designed for use with water based coolants using either ethylene glycol or propylene glycol antifreeze (ESAB
P/N's 156F05 or 0558004297) . Maximum design pressure is 200 psig (13 .8 bar) . Flow rates depend on the torch but typically
vary from .9 to 2 gpm (4 .1 to 9 .1 l/m) .
