Welding works on the machine
Preparation
Observe the operating manual of the diesel engine.
In order to protect electronic components as e. g. central processing
unit, monitor unit, sensors, relays etc., all connectors must be pulled
out prior to welding work.
The negative terminal of the welding appliance must be applied in
the vicinity of the weld directly on the component to be welded. Pay
attention that it has good contact and remove insulating colour coats.
If possible, keep welding leads away from the leads of the machine
(induction). If not possible, the welding leads must cross the machine
leads.
Touch with live electrodes only the welds. Other components may be
damaged if coming in contact with the electrodes. Prior to welding
works remove components which may get damaged by heat or
welding work.
Ensure that there are no inlfammable or combustible materials /
gases (e.g. fuel, oil, etc.) can get into the vicinity of the welds.
