Replacement of Electrode


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.

REMARKS: * 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.


  1. 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:

Dust Removal


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.

Keep the Welder Cable Plug in good condition


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.

WARNING:


  • 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.



  1. Troubleshooting




Breakdown

Analysis

Solutions



Yellow Indicator is on

Bad power ventilation lead to over-heat protection

Improve the ventilation condition.

Circumstance temperature is too high

It will automatically recover when the

Temperature low down

Using over the rated duty-cycle

The adjustment knob on the front panel didn’t work

Potentiometer broken (current regulation)


Replace the potentiometer.


Cooling Fan not working or turning very slowly

Switch broken

Replace the switch

Fan broken

Replace or repair the fan

Wire broken or falling off

Check the connection



No no-load voltage

Over voltage, under voltage or scarcity of phase

See No. 1

Welder getting overheated

See No. 1

Switch broken

Replace the switch


Electrode Holder and Cable getting

hot;“+” “-” polar sockets becoming hot

Electrode Holder’s capacity is too small;

Replace it with a bigger capacity one

Cable is of small size

Replace it with another one in conformity with the requirement

Socket loosen

Remove the oxide skin and tighten it

Bigger resistance between the electrode holder and the cable



Power source tripping

Resume power over a long period of time ( more than two days )

Not failure. Trip caused by the main power filter’s capacity charging. Switch 6 on the main power source.
