7. Before commissioning

• Check the electrical connection for sufficient pro-
tection (16 A)
• Wear required clothing see fig 3:
1. Welder's helmet
2. Welder's apron
3. Welder's gloves
• Make sure that no other persons stay in working or
hazardous area.
• Make sure that no combustible materials are found
in the working area.
Connecting to the mains power supply
• Before you connect the power cable (7) to the
mains power supply, make sure that the data on
the rating plate is the same as that for your mains
supply.
Important! The mains plug may only be replaced by
a qualified electrician.

Connecting the welding cable (Fig. 4)
• Important! Always make sure the device is un-
plugged before carrying out any connection work
on the welding cable (8/9)!
• Connect the welding cable as shown in Fig. 4. To
do so, connect the two connectors (10) on the elec-
trode holder (8) and the ground terminal (9) to the
corresponding quick-lock couplings (5/6) and lock
the connectors (10) in place by turning them in a
clockwise direction.
• The cable with the electrode holder (8) is normally
connected to the positive pole (5) and the cable
with the ground terminal (9) to the negative pole
(6).
Switching ON/OFF (Fig. 2)
• To switch on the device, turn the potentiometer (1)
in a clockwise direction from the zero position on
the welding current scale (2). The indicator lamp
for operation (3) then comes on.
• To switch off the device, turn the potentiometer (1)
in a counterclockwise direction back to the zero
position on the welding current scale (2). The indi-
cator lamp for operation (3) then goes out.

8. Operation

Welding preparations
• Connect the earth terminal (9) direct to the part
to be welded or to the support on which the part
is resting.
• Ensure that the earth terminal is in direct contact
with the part to be welded. You should therefore
avoid coated surfaces and/or insulated materials.
The electrode holder cable has a special clamp at
one end, which is used to secure the electrode.
• The welding safety shield must be used at all times
for welding. It protects your eyes from the radiation
emitted by the arc and nevertheless enables you to
watch the welding process.
Welding
Connect all the electrical connections for the pow-
er supply and for the welding current circuit. Most
coated electrodes are connected to the positive pole.
However, some types of electrode have to be con-
nected to the negative pole. Ensure that you observe
the information supplied by the manufacturer in rela-
tion to the type of electrode and correct polarity. Fit
the welding cables (8/9) to the quick-lock couplings
(5/6) accordingly.
Then fasten the unsheathed end of the electrode in
the electrode holder (8) and connect the ground ter-
minal (9) to the part you wish to weld. Ensure that a
good electric contact is made.
Switch on the device and set the welding current, de-
pending on the electrode used, using the potentiom-
eter.
Hold the safety shield in front of your face and rub
the tip of the electrode on the part you wish to weld
as if you were striking a match.
