3. Oxygen (O
2
) Plasma
• Oxygen is recommended for cutting ferrous materials.
• Provides faster cutting speeds.
• Provides very smooth finishes and minimizes nitride build-up on cut surface (nitride build-up can cause
difficulties in producing high quality welds if not removed).
4. Nitrogen (N2) Plasma
• Provides better cut quality on nonferrous materials such as stainless steel and aluminum.
• Can be used in place of air plasma with air shield or carbon dioxide (CO
2
).
• Provides much better parts life than air.
• A good clean welding grade nitrogen should be used.
B. Shield Gases
1. Compressed Air Shield
• Air shield is normally used when operating with air plasma.
• Improves cut quality on some ferrous materials.
• Inexpensive - reduces operating costs.
2. Nitrogen (N2) Shield
• Nitrogen shield is used with Ar/H2 (H35) plasma.
• Provides smooth finishes on nonferrous materials.
• May reduce smoke when used with Ar/H2 plasma.
3. Water Shield
• Normally used with nitrogen, Ar/H2, or air plasma.
• Provides very smooth cut surface.
• Reduces smoke and heat input to the workpiece.
• Effective up to 1/2 inch (12.7 mm) maximum material thickness.
• Tap water provides low operating expense.
4.06 Power Supply Status Codes
On start-up and during operation, the power supply control circuitry performs various tests. If the circuitry
detects a condition requiring operator attention, the status indicator on the control panel flashes a 2-part code
to indicate a code group and then a particular condition within the group. After 4 seconds, the sequence
repeats.
Example: Indicator flashes 4 times; the condition is in group 4. After a 1.2 second delay, the indicator blinks
3 times; the condition code is 4-3, indicating that the coolant is overheating. After a 4-second delay, the
indicator repeats the sequence until the condition is corrected.
Some conditions can be active indefinitely, while others are momentary. The power supply latches momentary
conditions; some momentary conditions can shut down the system. The indicator may show multiple condi-
tions in sequence; it is important to recognize all possible conditions that may be displayed.
Note
These codes are for systems with Firmware versions 2.4 or later. If your system’s Firmware is a prior version,
contact your distributor for updates.
