The ON/OFF power switch is set to
ON (I), but the power ON LED is not
illuminated.
• Verify that the power cord is plugged into the receptacle.
• Verify that the power is ON at the main power panel or at the
line-disconnect switch box.
• Verify that the line voltage is not too low (more than 15% below the rated
voltage).
• Verify that the fuses in the disconnect are not blown.
The arc does not transfer to the
workpiece.
• Clean the area where the ground clamp contacts the workpiece to
ensure a good metal-to-metal connection.
• Inspect the ground clamp for damage, and repair as necessary.
• The pierce-height distance may be too large. Move the torch closer to
the workpiece and fire the torch again.
The arc blows out, but re-ignites when
the torch trigger is pressed again.

damaged. See Inspect the Powermax125 consumables on page 109.

filter element on page 116.
