INITIAL INSTRUCTION
Generally
1. Main switch
This switch turns the machine on and
off. When the main switch is switched
off, a clicking sound may appear from
the machine whilst the green LED on
the front (6) flashes. This is normal and
is not an error.
2. Mains cable
Entry point for mains voltage supply
cable
3. Welding cable sockets
DC positive and negative welding
current outlet sockets. Electrode cable to be fitted in positive or negative outlet socket in con-
formity with the polarity of the electrode, and earth return cable to be placed in remaining
socket.
4. Welding current control
This knob is used for adjustment of the welding current. The welding current is adjustable from:
10-140A on DELTA 140E
20-160A on DELTA 160E.
5. Overheating
The yellow LED will alight if the machine is disconnected due to overheating. Overheating
arises if the machine is overloaded. The machine automatically reconnects when the
temperature has fallen, and the yellow LED will switch off.
Warning:
When the machine is overheated, it is important to place the electrode holder/torch so as to
avoid the risk of establishing the arc when the machine reconnects automatically.
6. The green LED is alight when the machine is switched on
MAINTENANCE
DELTA 140E/160E 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.
