SECTION 1: DESCRIPTION
OF EQUIPMENT
1.1 General Information
A. 500 Amp System
A complete 500 amp TA500 system includes:
• M200 machine mounted torch with either 15, 25, 35
or 50 foot (4.6, 7.6, 10.7 or 15.2 meter) leads.
• Introductory spare parts kit for torch.
• Thermal Arc TAC 500 Power Supply.
• Pilot Arc Starter.
• Supply Console for gas and water connections
and power manifolding.
• Operator Control Panel (with or without enclo-
sure) that contains all switches, controls and
indicator lights necessary to direct system func-
tions.
• HE 200 Coolant Recirculator, a closed loop sys-
tem that recirculates, deionizes and cools the
torch coolant.
• Gas Regulators for assuring constant working
pressure regardless of variation in inlet pres-
sure.
• Supply hoses and cables to interconnect all com-
ponents in lengths required for the particular
installation. This must be decided prior to or-
dering the system. Refer to CC65 catalog C500 for
ordering details.
B. 1000 Amp System
A complete 1000 amp TA500 system consists of the same
components as the 500 amp system plus an additional TAC
500 Power Supply (connected in parallel with another TAC
500), an 8 foot long parallel control cable, two negative power
cables and two positive work cables.
C. Options
• A Hi-Flow Water Shield Assembly to reduce
smoke, noise and glare.
• Torch Standoff Control that automatically sets
and maintains the torch a fixed distance above
the metal being cut.
