Panasonic AC/DCTIG arc welding power source YC-500 WX

1. Check for abnormal vibration, beat or smell.

2. Check for abnormal heating at the cable connections.

3. Ensure that the welding machine cooling fan rotates smoothly with power ON.

4. Check the switch for abnormal operation.

5. Check for poor cable connection and insulation.

6. Check the cable for any possible disconnection.

1. Checking electrical connection sections

Ensure that tightening screws at the input and output side cable connections of welding machine are not loose, rust does not worsen the electric contact, and check for any problem in insulation.

Ensure that the welding machine case is completely grounded.

3. Removing dust inside the welding machine

If dust is accumulated between windings of the transformer, for example, insulation may deteriorate accordingly, therefore, remove the side top plates of the welding machine at least once per 6 months, and blow compressed air with less moisture against each section for cleaning.;

Do not touch the spark is gap in normal case. (The distance between spark gap is adjusted for 1.2mm) When the electrode is significantly no-uniform and contaminated on the surface, clean the surface, and then adjust the spark gap for 1.2mm. (To do this, use a thickness gauge.)

When removing a top panel, side panel and rear panel for maintenance and inspection, do not fail to re-install them just as they were.;
