MAINTENANCE

Frequency of maintenance operations depends on the operating conditions:

how intensively the welder is used, how clean or dirty the welding site is

(aggressive atmospheres, etc).

Before use, always inspect the welder, checking for security and cleanliness of

arms and electrodes to ensure they are in perfect condition. Ensure also that

the power cable is in perfect condition at all times.

As a general rule the power supply should be inspected internally at least

twice a year.

1. Access the inside of the machine by removing the screws securing the side

cover and carefully hinge the cover down.

2. Clean the transformer using a blast of dry compressed air with a maximum

pressure of 10 bar. NEVER direct the compressed air jet on to the circuit

boards. These should be cleaned with a soft brush and vacuumed or

blown with air at very low pressure. ALWAYS use a face mask for these

operations.

3. Check all wiring for insulation damage or loose or oxidised connections.

Repair/replace where necessary. Check all screws and connections are

tight and there are no signs of oxidation or overheating.

4. Replace the cover.

WARNING: ELECTRICITY CAN KILL. NEVER TOUCH LIVE ELECTRICAL

COMPONENTS. DISCONNECT THE POWER SUPPLY BEFORE ALL

INSPECTIONS AND MAINTENANCE OPERATIONS. BEWARE HOT

SURFACES......ALWAYS LET THE MACHINE COOL DOWN BEFORE

ACCESSING INTERNAL COMPONENTS.

WARNING: NEVER CONNECT THE MACHINE UNLESS THE COVER IS

REPLACED.
