4.1 set up
•
Select an appropriate condition from the process data (SDP File) and install recommended torch front-
end parts (nozzle, electrode, etc.) See process data to identify parts and settings.
•
Position torch over material at desired start location.
•
See Power Source Manual for proper settings.
•
See Flow Control Manual for gas control procedures.
•
See Control and Machine Manuals for startup procedures.
4.1.1 Mirror cutting
When mirror cutting, a reverse swirl gas baffle and reverse diffuser are required. These reverse parts will "spin"
the gas in the opposite direction, reversing the "good" side of the cut.

cut Quality
a.
Introduction
Causes affecting cut quality are interdependent. Changing one variable affects all others. Determining a solu-
tion may be difficult. The following guide offers possible solutions to different undesirable cutting results. To
begin select the most prominent condition:
4.2.2
4.2.3
4.2.4
4.2.5
4.2.6
Usually the recommended cutting parameters will give optimal cut quality, occasionally conditions may vary
enough that slight adjustments will be required. If so:
•
Make small incremental adjustments when making corrections.
•
Adjust Arc Voltage in 5 volt increments, up or down as required.
•
Adjust cutting speed 5% or less as required until conditions improve.
oil and grease can Burn Violently!
• Never use oil or grease on this torch. • Handle torch clean hands only
on clean surface.
• Use silicone lubricant only where directed.
• Oil and grease are easily ignited and burn violently in the presence
of oxygen under pressure.
