2.5.2 pt-36 torch technical specifications
type:
Water cooled, Dual gas, mechanized plasmarc cutting torch
current rating:
1000 Amps @ 100% duty cycle
Mounting Diameter:
2 inches (50.8 mm)
length of torch without leads:
16.7 inches (42 cm)
IEc 60974-7 Voltage rating:
500 volts peak
striking Voltage (maximum value of hI-frEQuENcY voltage):
8000 vac
Minimum coolant flowrate:
1.3 USGPM (5.9 l/min)
Minimum coolant pressure at Inlet:
175 psig (12.1 bars)
Maximum coolant pressure at Inlet:
200 psig (13.8 bar)
Minimum acceptable rating of coolant recirculator:
16,830 BTU/HR (4,9 kW) at High Coolant Temperature - Ambient = 45
°
F (25
°
C) and 1.6 USGPM (6 L/min)
Maximum safe gas pressures at Inlets to torch:
125 psig (8.6 bars)
safety Interlocks:
This torch is intended for use with ESAB Plasmarc cutting systems and controls employing a water flow
switch on the coolant return line from the torch. Removal of the nozzle retaining cup to service the torch breaks the
coolant return path.
