SECTION 2 DESCRIPTION
2.5.2 PT-36 Torch Technical Specications
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 ow
switch on the coolant return line from the torch. Removal of the nozzle retaining cup to service the torch breaks the
coolant return path.
