- Hold the welding screen in front of your face and move the welding

nozzle to the point on the workpiece where you wish to complete the

weld. Now press the torch switch.

- When the arc is burning, the welding set will feed wire into the weld

pool. When the weld nugget is large enough, move the torch slowly

along the required edge. Move it to and fro if necessary to enlarge

the weld pool a little.

- Find the ideal setting of the welding current and wire feed speed by

carrying out a test weld. Ideally an even welding noise will be

audible. The penetration depth should be as deep as possible, but

the weld pool must not be allowed to fall through the workpiece.

- Do not remove the slag until the weld has cooled. If you want to

continue a welding job on an interrupted weld seam, the slag from

your initial attempt must first be removed.

11.Safety equipment

Thermostat

The welding set is fitted with an overheating guard that protects the

welding transformer from overheating. If the overheating guard trips,

the control lamp on your set will be lit. Allow the welding set to cool

for a time.

12.Maintenance

Frequency of maintenance operations depends on the operating

conditions, how intensively the welder is used, and how clean or dirty

the welding site is (aggressive atmospheres, etc).

Always inspect the cables, both earth and torch cable, before use to

ensure they are in perfect condition.

Ensure the earth clamp is clean and secured correctly to the cable.

Check the hose for security and serviceability.

As a general rule the covers should br removed and the transformer,

and other components, should be inspected at least annually.

Consult your dealer for advice if necessary.

Welding shield

Always maintain the welding mask in good condition. If the clear

glass protection lens becomes badly pitted, sufficient to interfere

with vision, or cracked, have it replaced immediately.

Replacement clear and dark lenses are available from your dealer -

see Parts Lists for details. NEVER use any dark filter lens other than

that provided by my company, or one with the same certified 'Optical

class' (degree of protection).

The shield should always be cleaned with a clean soft cloth after use,

ensuring the lenses are clean. Remove any dust that may have

accumulated and store it in a safe place where it cannot be damaged.

NEVER use a shield that is not in perfect condition.
