2.05 Requirements to Complete
System
To complete the system, the user needs the following:
• Remote signal to operate Arc ON/OFF via TB-1 in-
terface or J-20 receptacle using accessory remote de-
vice
• Gas Pressure Regulators. Both Argon Gas Regula-
tor and Argon/Hydrogen Gas Regulators are avail-
able through Thermal Dynamics
2.06 Options, Accessories, and
Replacement Parts
Options and accessories are available for the ULTIMA-150
Plasma Welding Power Supply to customize it for a particu-
lar application or to further enhance performance. For more
information, refer to Section 6, Parts Replacement.
• Quick Disconnect Adapter Kit - For use with older
model Thermal Arc torches. The Adapter Kit retro-
fits the torch for direct connection to the quick dis-
connect receptacle on the Power Supply.
• Torch Spare Parts Kit - Kit contains replacement front
end torch parts.
• Remote Current Control Device - Required for opera-
tion of the ULTIMA-150 Plasma Welding System.
• Weld Sequencer - An add-on accessory for control-
ling weld timing, pulsing, current slope, and gas
slope.
2.07 Introduction to Plasma Arc
Welding
Plasma is a gas which has been heated to an extremely
high temperature and ionized so that the gas becomes elec-
trically conductive. The welding process uses this electric
arc to transfer an electric arc to the workpiece. The metal to
be welded is melted by the heat of this arc.
In a Thermal Arc Plasma Welding Torch, a cool gas such
as argon enters Zone A (Figure 2-2). In Zone B, a pilot arc
between the electrode and the front of the torch heats and
ionizes the gas. An arc transfers to the workpiece through
the column of gas in Zone C.
