Troubleshooting
7Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| OVERHEATING | OVERUSE | L Allow cooling period; follow rated duty cycle. l Reduce current or reduce duty cycle before starting to weld again. l Do not block or filter airflow to unit. |
| STATIC (ESD) | L Put on grounded wrist strap BEFORE handling boards or parts. l Use proper static-proof bags and boxes to store, move, or ship PC boards. | |
| MOVING PARTS | L Keep away from moving parts. l Keep away from pinch points such as drive rolls. | |
| WELDING WIRE | L Do not press gun trigger until instructed to do so. l Do not point gun toward any part of the body, other people, or any metal when threading welding wire. | |
| BATTERY EXPLOSION | L Do not use welder to charge batteries or jump start vehicles unless it has a battery charging feature designed for this purpose. | |
| H.F. RADIATION | L High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment. l Have only qualified persons familiar with electronic equipment perform this installation. l The user is responsible for having a qualified electrician promptly correct any interference problem resulting from the installation. l If notified by the FCC about interference, stop using the equipment at once. l Have the installation regularly checked and maintained. l Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and shielding to minimize the possibility of interference. | |
| ARC WELDING | L Electromagnetic energy can interfere with sensitive electronic equipment such as microprocessors, computers, and computer-driven equipment such as robots. l Be sure all equipment in the welding area is electromagnetically compatible. l To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor. l Locate welding operation 100 meters from any sensitive electronic equipment. l Be sure this welding machine is installed and grounded according to this manual. l If interference still occurs, the user must take extra measures such as moving the welding machine, using shielded cables, using line filters, or shielding the work area. |
