aVoiding wire Feeding Problems
Wire feeding problems can be avoided by observing the following
gun handling procedures:
1. Do not kink or pull cable around sharp corners.
2. Keep the electrode cable as straight as possible when welding or
loading electrode through cable.
3. Avoid wrapping excess cable around handle or front of wire
feeder.
4. Do not allow dolly wheels or trucks to run over cables.
5. Keep cable clean by following maintenance instructions.
