ENGLISH

Approach the weld metal with the elec-
trode. 

Contact of the electrode to the weld 
metal causes a short-circuit, the welding 
current is reduced. The material is 
heated up and a short arc generated. 

By lifting the electrode the arc is started 
and will burn at the set welding current. 

1.

Set master switch to “0”. 

2.

Disconnect the earth cable from the 
workpiece. 

3.

Unplug the power cable. 

This welding machine contains no user-
serviceable parts. 

Depending on dust accumulation the 
dust should be blown out from the 
machine with dry and oil-free com-
pressed air every 4 - 6 months. 

Periodically perform a check for visible 
damage. 

 

Contact a qualified electrician if any of 
the cables are damaged. 

For special welding tasks the following 
accessories are available at specialised 
dealers – see back cover for illustrations. 

These accessories have been tested 
with the machine and ensure operation 
without any problem.

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. 

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 paper 
produced with elemental chlorine free 
bleaching process. 

The welding machine is equipped with 
an overload protection. It will automati-
cally turn OFF in case of excessive oper-
ating temperatures and under- or over-
voltage. 

− The “Fault” indicator light is flashing. 

In case of an excessive operating tem-
perature:

− DO NOT turn the machine OFF, 

in order for the fan to cool the 
machine down faster. 

− The “Fault” indicator light will go out 

when the temperature has fallen off 
to normal levels. 

 

You can now continue welding. 

In case of under- or overvoltage:

− Check the mains voltage.

Workpiece not 
clean?

Remove rust, 
grease or other 
contamination 
prior to welding.

Earth cable mak-
ing poor contact?

Check earth 
cable for proper 
contact.

The “Fault” indi-
cator light is 
flashing.

Check mains 
voltage and fan

Electronics
