Connection and operation
Warning
Read warning notice and instruction
manual carefully prior to initial
operation and save the information for
later use.
Permissible installation
Mains connection
Connect the machine to the correct mains supply. Please read the
type plate (U
) on the rear side of the machine.

Important!
In order to avoid destruction of plugs and
cables, good electric contact is required when
connecting earth cables and welding hoses to
the machine.
Connection of shielding gas
Connect the gas hose, which branches off from the back panel of
the welding machine (3), to a gas supply with pressure regulator
(0-8 bar). (Note: Some types of pressure regulators require an
output pressure of more than 2 bar to function optimally).
Adjustment of wire brake
The wire brake must ensure that the wire reel brakes sufficiently
before the welding wire runs over the edge of the reel.
The brake force is dependent on the weight of the wire reel and
wire feed speed.
Adjustment:
•
Adjust the wire brake by fastening
or loosening the self-locking nut on
the axle of the wire hub.
Inching
This function is for wire inching/feeding,
e.g. after change of wire. To feed the
wire, press and hold down the key while
triggering the torch trigger.

Selecting welding polarity
Polarity reversal is recommended
for certain types of welding wire, in
particular Innershield welding wire. For
recommended polarity, please refer to
the welding wire packaging.
Change of polarity:
1. Disconnect the machine from the
mains supply.
2. Dismount the milled nuts at the
poles (fig. 1).
3. Reverse the cables (fig. 1).
4. Mount the milled nuts (fig. 1).
5. Exchange earth cable from minus to
plus (fig. 2).
6. Connect the machine to the mains
supply.
Material consumption
Material consumption can be estimated by calculating welding
time in minutes times wire feed speed (m/min) times weight per
meter of the welding consumables in use.
