• Verify that the line voltage is not too low (more
than 15% below the rated voltage).
• Verify that the circuit break has not been tripped.
The arc does not transfer to the
workpiece.
• Clean the area where the work clamp contacts
the workpiece to ensure a good metal-to-metal

necessary.

the torch closer to the workpiece and fire the torch
again.
