2.02 ULTIMA-150 Power Supply
Description
The ULTIMA-150 Plasma Welding (European/EMC)
Power Supply is one integrated unit providing power, pi-
lot control inverter, and coolant recirculator. With output
ranges from 0.5-15 amps and 5-150 amps, the power sup-
ply is ideally suited for all low current gas tungsten arc
welding (GTAW) and automated welding applications.
Suitable for use with all designated Thermal Dynamics
plasma welding torches.

D. Protection Features
A number of interlocks have been to provided to assure
proper handling of fault conditions at all times.
• Coolant flow and level - Monitored and shut down
the recirculator pump when below minimum levels.
• Pump operation - System shuts down due to air in
torch leads or in the system.
• Coolant and power supply - Over temperature of the
power supply or coolant will immediately disable
the power supply output. The recirculator pump re-
mains running for system and coolant cool down.
• Plasma gas and shield gas - Both have minimum
pressure switches that disable pilot arc operation.
• Pilot arc - Always latched off in event of power sup-
ply interlock trip. The pilot must be disabled and
then re-energized to initiate the pilot arc after a fault
shutdown.
