ENGLISH
Increasing this value leads to a better
cleaning effect (aluminium welding), but
at the same time subjects the electrode
to a higher thermal stress.
Setting range: 30 %...70 %.
Gas-shielded arc welding
A
Caution!
Check before starting
work:
− Correct shielding gas connected?
− Correct gas shroud fitted?
− Electrode tip still pointed?
Regrind if necessary.

Note:
Grind electrodes for DC welding
in lengthwise direction only.
1. Attach earth cable at a suitable loca-
tion to the workpiece.
2. Open cylinder valve and set desired
gas flow rate.
Change gas shroud, if necessary.
3. Switch master switch ON.
4. Select desired welding process.
5. Set desired welding current.
The welding machine is now opera-
tional.
Manual arc welding
1. Attach earth cable at a suitable loca-
tion to the workpiece.

7. Maintenance
This welding machine contains no user-
serviceable parts.
Depending on dust accumulation the
dust should be blown out from the
machine with dry compressed air every
4 - 6 months.
Periodically perform a check for visible
damage.
Contact a qualified electrician if any of
the cables are damaged.
8. Repairs
A
Danger!
Repairs to power tools must be
carried out by qualified electricians
only!
Welding machines in need of repair can
be sent to the service centre of your
country. Refer to the spare parts list for
the address.
Please attach a description of the fault to
the power tool.
9. Environmental Protection
The machine's packaging can be 100%
recycled.
Worn out power tools and accessories
contain considerable amounts of valua-
ble raw and rubber materials, which can
be recycled.
These instructions are printed on chlo-
and
rine-free bleached paper.
10. Disorders
Excess temperature
The welding machine is equipped with
an overload protection. If the operating
temperature exceeds permissible levels
the machine is shut down automatically.
− The following message will appear
in the display:
"EXCESS TEMP"
"PLEASE WAIT".
− DO NOT switch the machine OFF,
in order for the fan to cool the
machine down faster.
− If the temperature has fallen off to
normal levels, the display will show
the welding current again.
You can now continue welding.
Low voltage
The machine's control has detected a
supply voltage of more than 10% below
the rated voltage.
The following message will appear in the
display:
"LOW VOLTAGE"
"SWITCH OFF".
2
, 3 m
To prevent excess primary currents the

acknowledgement.
− Switch the machine OFF for 5 sec-
ondsm then ON again.
− If the error message appears again,
switch OFF and contact a qualified
electrician!
11. Trouble Shooting
Gas line connec-
tion not tight?
