Maintenance and Service
Unlike the traditional transformers, the inverter welding machines belongs to the group of scientifically
sophisticated products 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 machines was mobile.
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.
