2.02 ULTIMA-150 Power Supply
Description
The ULTIMA-150 Plasma Welding Power Supply is one
integrated unit providing power, pilot control inverter, and
coolant recirculator. With output ranges from 0.5-15 amps
and 5-150 amps, the power supply is ideally suited for all
low current gas tungsten arc welding (GTAW) and auto-
mated welding applications. Suitable for use with all des-
ignated 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.
