OPERATING INSTRUCTIONS

1. Ensure that the work environment and your clothing meet the safety requirements outlined in

the 

Safety 

section.

2. Follow the instructions in the 

Setup 

section.  Verify that the input gas supply pressure is set to

90 psi (6.2 bar).

3. At the rear of the power supply, set the power switch to the ON (I) position.  The POWER ON,

GAS PRESSURE and LINE VOLTAGE LEDs should illuminate green.  The TEMP LED should
remain extinguished.

4.

Adjust the gas pressure REGULATOR to read 70 psi (4.8 bar)

 

on the PRESSURE GAUGE:

Pull the REGULATOR CAP out

Push the GAS TEST switch in

Turn the REGULATOR CAP while still holding in the GAS TEST switch

After adjustment to 70 psi (4.8 bar), release the GAS TEST switch

Push the REGULATOR CAP back in

Note: If using 50 ft (15.2 m) torch leads, adjust pressure to 75 psi (5 bar).

5. Adjust the AMPS knob to the desired setting.  See 

Cut Chart later in this section if necessary.

     WARNING

Before operating this system, read the Safety section of this manual thoroughly!
