troubleshooting checklist in the Operator Manual.
• Examine the cartridge:

• Are the power cord wires connected correctly
and fully tightened in the plasma power supply
and in the power plug or line-disconnect box?
• Is the ground wire connected correctly?
• Is the power plug correct for the power cord?
• Examine the work lead and work clamp:
• Is the work lead connected correctly to the
plasma power supply?
• Is the work clamp connected to the workpiece
that you are cutting? Does it have good
metal-to-metal contact?
• Examine the torch and torch lead:
• Is the torch lead twisted or kinked?
• Is the O-ring on the torch head dry, cracked,
or damaged?
• Is the mechanized cutting system correctly grounded and
shielded? For best practices, refer to the Mechanized
Cutting Guide.
