Inspect the welding machine regularly, with a frequency depending on use and the dustiness of the environment, and
remove the dust deposited on the transformer, using a jet of dry compressed air (max. 10 bar).
At the same time make sure the electrical connections are tight and check the wiring for damage to the insulation.
At the end of these operations re-assemble the panels of the welding machine and screw the fastening screws right
