CHECK

 

 

 

Machine is unresponsive immediately after

1. There is a 4 second soft start period for pre-charging the input fil-

power-up.

 

 

ter capacitors. Wait until that time is up. The Power LED will light

 

 

 

 

when ready. If not, refer to the first part of this section.

 

 

 

 

 

The Air Low LED is lit

 

1.

Make sure there is at least 80 psi connected to the gas connec-

 

 

 

 

tion at the back of the machine.

 

 

 

 

2.

Press the Purge button and set the regulator to 70 psi. The pres-

 

 

 

 

sure may increase when air stops flowing but this is normal. Do

 

 

 

 

not reset the pressure while the air is OFF.

 

 

 

 

3.

Possible faulty Pressure Switch.

 

 

 

 

4.

Possible faulty Control board.

 

 

 

 

 

The Safety LED is flashing

 

1.

Make sure there is a Lincoln torch and cable assembly connect-

 

 

 

 

ed properly to the Pro-Cut bulk head connector.

 

 

 

 

2.

Check consumables for proper installation or excessive wear.

 

 

 

 

Replace if excessively worn. If not, use a piece of fine emery

 

 

 

 

cloth to remove any oxide buildup on the tip of the electrode.

 

 

 

 

 

The Safety LED is lit and steady

 

1.

Press the Reset button. If torch and consumables are properly

 

 

 

 

installed, the Safety LED should turn off. Normal cutting or goug-

 

 

 

 

ing can resume.

 

 

 

 

 

The Thermal LED is lit

 

1.

The machine's thermostat has tripped due to exceeded duty

 

 

 

 

cycle limits. Do NOT turn the power off. Allow the machine to

 

 

 

 

cool for 15 - 30 minutes and the thermostat will reset itself.

 

 

 

 

2. The machine's air louvers or fans are obstructed such that air

 

 

 

 

cannot flow to properly cool the machine. Remove any foreign

 

 

 

 

material that may block air flow. Blow the machine out with a

 

 

 

 

clean, dry air stream.

 

 

 

 

3.

Possible faulty Control board.
