Basic Welding Procedure

Replacement of Electrode

a) Connecting the power source switch, (Power Indicator Light) bright;

b) Regulate the welding current potentiometer to reach the value for welding;

c) Take-up the torch hand, aim at the welding seam, use the stick contact with the work piece and

then the electric arc was ignited, i.e. you can effect the arc welding at the same time the (Welding

Indicator Light) bright.

Only when the electrode burns up to 1~2 cm away from the electrode holder does it become

necessary to replace it with a new one in order to proceed with welding.

: * Electrode burns at high temperature. Please do not use hand to replace it. The

replaced electrode end should be placed in a metal container;

* Do not use the electrode holder to clamp the electrode coating;

* While ignite the electric arc, you should scrap lightly, or it may adhere to the stick.

REMARKS

8. Maintenance

Unlike the traditional welder, the reversible welder belongs to the scientifically sophisticated product

which uses the modern electronic component parts combined with state-of-the art technology.

Therefore the trained personnel are required for its maintenance. However, due to the fact that there

are very few components to be easily worn out, it doesn't need regular service apart from usual

cleaning work. Only the qualified people are allowed to be in charge of the repair job. It is strongly

recommended that customers contact our company for the technical back-up or service when they

feel unable to work out the technical hitch or problems.

The Maintenance includes:

The professional service man must regularly clean up the dust from the welder by the dry

compressed air (air compressor or the similar device). Meanwhile examination can also be

performed to make sure there are no loose parts and components inside the machine. Immediate

cleaning is needed if there is an accumulation of dust.

Under normal circumstance cleaning is only required once a year unless there is too much dust

inside the welder. If so, cleaning needs to be done every quarter of the year.

The Welder Cable Plug needs to be checked from time to time. In its regular usage, at least it has to

be inspected each month. However, it is necessary to check it every time when it is in the mobile

circumstance.

If the main loop voltage happens to be a bit higher, safety precaution should be taken before repair

to avoid accidental shock. The untrained people are forbidden to open the case!

Power source needs to be cut off before dust removal;

Never tamper with wire or damage the component parts when cleaning.

Dust Removal

Keep the Welder Cable Plug in good condition
