by the ESP-101, refer to the maintenance and troubleshooting sections of this manual. If the problem is not corrected after
referring to the maintenance and troubleshooting sections, contact your ESAB distributor.
A. Insucient Penetration.
1. Current too low.
2. Cutting speed too fast.
3. Damaged cutting nozzle.
4. Improper air pressure.
5. Low air ow rate.
6. Stando too high - Nozzle to plate distance.
B. Main Arc Extinguishes.
1. Cutting speed too slow.
2. Worn electrode.
3. Stando too high - Nozzle to plate distance.
C. Dross Formation. (In some materials and thicknesses, it may be impossible to get dross-free cuts.)
1. Current too low.
2. Cutting speed too fast or too slow.
