Only qualified personnel should perform this maintenance.

Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.

Do not touch electrically hot parts.

ommended. If the contacts are replaced reset the gap spacing to 0.015. Refer to figure C.1. Note in highly dirty environments where there is an abun- dance of conductive contaminants, use a low pres- sure air stream to clean the spark gap. Do not dis- turb the factory setting.

8.Inspect gas hose and inlet fitting for cracks or leaks.

9.Replace any unreadable labels or decals.

10.Verify that the machine and welding circuit is prop- erly grounded.

WARNING

To avoid receiving a high frequency shock, keep the TIG torch and cables in good condition.

ROUTINE AND PERIODIC MAINTENANCE

1.Disconnect power supply lines to machine before performing periodic maintenance.

2.Periodically clean the inside of the machine with a low pressure air system. Be sure to clean the following components thoroughly.

Main Transformer

Electrode/Gas Output Receptacle

Polarity Switch

Rectifier Assembly

Arc Starter/Spark Gap Assembly

PC Boards

Fan Blades

3.Inspect welder output and control cables for fraying, cuts, and bare spots.

4.Keep TIG torch and cables in good condition.

5.Clean air louvers to ensure proper air flow and cooling.

6.The fan motor has sealed ball bearings which require no maintenance.
