Suggestions for Extra Utility from the PRO-CUT System:

WARNING

ELECTRIC SHOCK CAN KILL.

• Turn off machine at the disconnect switch on the front of the machine before tightening, cleaning or replacing consumables.

----------------------------------------------------------------------------

1.Occasionally an oxide layer may form over the tip of the electrode, creating an insulating barrier between the electrode and nozzle. This will result in the tripping of the Pro-Cut's safety circuit. When this happens turn the power off, remove the nozzle and electrode and use the electrode to rub against the inside bottom surface of the nozzle. This will help remove any oxide buildup. Replace the noz- zle, turn on the power and continue cutting. If the Parts-in-Place circuit continues to trip after clean- ing the consumables, then replace them with a new set. Do not continue to try and cut with exces- sively worn consumables as this can cause dam- age to the torch head and will degrade cut quality.

2.To improve consumable life, here are some sug- gestions that may be useful:

a.Never drag the nozzle on the work surface if the output control knob is above the mid range setting.

b.Make sure the air supply to the Pro-Cut is clean and free of oil. Use several extra in line filters if necessary.

c.Use the lowest output setting possible to make a good quality cut at the desired cut speed.

d.Minimize dross buildup on the nozzle tip by starting the cut from the edge of the plate when possible.

e.Pierce cutting should be done only when nec- essary. If piercing, angle torch about 30° from the plane perpendicular to the work piece, transfer the arc, then bring the torch perpen- dicular to the work and begin parallel move- ment.

f.Reduce the number of pilot arc starts without transferring to the work.

g.Reduce the pilot arc time before transferring to the work.

h. Set air pressure to recommended setting. A higher or lower pressure will cause turbulence in the plasma arc, eroding the orifice of the nozzle tip.

i. Use only Lincoln consumable parts. These parts are patented and using any other replacement consumables may cause damage to the torch or reduce cut quality.
