-
-
-
Checking and

(36)
(35)
(21) (37)
Warning! An electric shock can be fatal. Before opening up the welding
machine, switch it off, unplug it from the mains and put up a warning sign to
stop anybody switching it back on again. If necessary, discharge the
electrolytic capacitors.
Carry out safety inspections at the stipulated intervals (see the section headed
"Safety rules")
Depending on the machine location, but no less often than twice a year, remove the
housing and blow the inside of the power source clean with dry, oil-free, reduced-
blow compressed air. Do not aim air-jets at electronic components from too close a
range.
If a lot of dust has accumulated, clean the cooling-air ducts.
Note! Whenever the LCA 15 board is replaced, it is necessary to check and set
the maximum welding amperage (see the section headed "Measuring,
inspection and adjustment jobs").
