SECTION 3:

INSTALLATION

3.01 Site Selection

• Place in a clean and dry area.
• Provide adequate ventilation and fresh air sup-
ply.
• Ideal ambient temperature should not exceed
40°C / 104°F. Temperatures exceeding that may
diminish cutting capacity or quality.
• The cutting machine must be placed on an even,
firm surface so that it stands firmly.

3.02 Electrical Input Connections

Check your power source for correct voltage be-
fore plugging in or connecting the unit. The
primary power source, fuse, and any extension
cords used must conform to local electrical code
and the recommended circuit protection and wir-
ing requirements as specified in Section 2.0.
• This power supply includes an input power cord
and plug suitable for 115 VAC, 20 Amp, Single -
Phase input power.
A-04488
For 208 / 230 VAC input power, replace the supplied
power plug. Use only an approved replacement input
power plug with ground.
Replace the plug as follows:
1. Cut the original cord close to the plug.
2. Strip back the outer cord cover as needed to con-
nect the inner conductors to the replacement plug.
3. Connect conductors to the plug contacts according
to the plug manufacturer's instructions. All three
conductors must be connected to the plug.

CAUTION
115 V, 20A, 1Ø
Connect the input power cord as follows:
1. Check the power source for correct voltage before
plugging in the unit.
2. Connect the input power cable (or close the main
disconnect switch) to supply power to the system.

3.03 Compressed Air Connection

• An air compressor is required and should be con-
nected to rear panel of power source by air hose.
To replace fittings, use 1/4" NPT.
• Air pressure should be 65 psi (4.5 bar) (.45 MPa)
and air should be dry and clean.
• Air flow should be 400 scfh - 6.6 scfm (188.7 lpm)
minimum.

Do not cut in humid or wet surroundings.
• Before you maintain or replace torch parts, wait
for the post flow air cycle (approximately 10 sec-
onds), to stop, then turn the machine off.
• Always use original manufacturers parts. The use
of aftermarket parts could result in shorter parts
life and in unsatisfactory cutting results. Any war-
ranty claims would be waived.
Repairs must be done by skilled and qualified
personnel only.
