The length of the cooling periods depends on the current setting, and the machine should not be
interrupted during cooling. If the cooling periodes during use of the machine are not sufficiently
long, the overheating protection will automatically interrupt the welding process. The yellow LED will
alight and thus indicates that the machine has been disconnected due to overload. The LED
switches off when the machine has cooled down sufficiently. The permissible load can be seen
from the paragraph "Technical data".
Example:
60% max. load when MMA welding means that a cooling period of four minutes after welding for six
minutes is required at a current setting of 120 A; this calculation presupposes 10 minutes between
the start of each welding period.
The machine has been specially designed for simple welding jobs and is therefore not intended to
work with high loads over a long period of time.
Mobility
The carrying handle of the machine is strong enough to be used for movement or carriage,
including lifting by hoist or crane.
During operation the machine must not be carried around or fixed to a person.
Positioning
Due to its low centre of gravity the machine can also be placed on tilted bedplates; during its
operation, however, the machine should be placed in a way that will ensure that pulling of the
welding cables will not cause the machine to tip over.
It must be made sure that the air intake and outlet are not blocked, and the machine must not be
placed in a position that will obstruct the circulation of cooling air.
When used on scaffoldings and the like, the machine must be fastened properly. The handle may
be used for this purpose.
MIGATRONIC disclaims all responsibility, if the machine is used for any purpose other than
welding.
MAINTENANCE
DELTA 180E PFC requires virtually no maintenance. However, exposure to extremely dusty, damp
or corrosive air is damaging to the welding machine and in order to prevent problems arising, the
following procedure should be observed at least once a year or as occasion requires:
- disconnect the machine from the incoming mains supply
- clean the cooling ribs with compressed air or a soft brush without taking the machine apart.
Lack of maintenance can lead to reduced reliability and cancellation of the guarantee.
Please note that the guarantee will no longer apply if it has been attempted to take the machine
apart or to open the factory-made sealing of the machine.
