3.03 Primary Input Power Connections
Power Cords Included With Power Supply
Attached to the power supply is an input power cord with a 230 Volt 50 Amp NEMA 6-50P for plug. Supplied adapters allow for
connection of the power supply input cable plug when using 120V input power.

CAUTION
Check your power source for correct voltage before plugging in or connecting the unit. The primary
power source, fuse, and any extension cords used must conform to local electrical code and the rec-
ommended circuit protection and wiring requirements as specified in Section 2.

B. Using Industrial Compressed Air In Gas Cylinders
When using Industrial compressed air in gas cylinders as the gas supply:
1. Refer to the manufacturer’s specifications for installation and maintenance procedures for high pressure gas regulators.
2. Examine the cylinder valves to be sure they are clean and free of oil, grease or any foreign material. Briefly open each
cylinder valve to blow out any dust which may be present.
3. The cylinder must be equipped with an adjustable high - pressure regulator capable of outlet pressures up to 100 psi
(6.9 bar) maximum and flows of at least 250 scfh (120 lpm).
4. Connect gas supply hose to the cylinder.
NOTE
Pressure should be set at 100 psi (6.9 bar) at the high pressure gas cylinder regulator.
Supply hose must be at least 1/4 inch (6 mm) I.D.
For a secure seal, apply thread sealant to the fitting threads, according to manufacturer's instructions.
Do Not use Teflon tape as a thread sealer, as small particles of the tape may break off and block the
small gas passages in the torch.
