DESCRIPTION



  This direct current welding unit for single phase is designed according to safety standard EN60974-

1:2005. The unit is primarily designed for welding metals such as copper, low carbon steel, low alloy 
steel, stainless steel etc. 



  The unit is compact and portable and easy to strike and has high tolerance to mains voltage 

fluctuations. The unit can be used for welding in all positions. 



  The unit is used for arc welding with acid or basic coated electrodes. 



  The unit is built with a high frequency inverter, which gives a low weight and good performance. 



  The welding current is variably adjustable and can be adapted to the thickness of the workpiece. 



  The unit has a down ramping function and a duty cycle up to 60%. 



  The unit is fan cooled and has voltage indication and indication for the overheating protection. 



  The unit can be transported using the carrying strap and handles. 



  Accessories included: Electrode holder, earth clamp, welding cable 2 m, welding cable 1.5 m, 

chipping hammer, wire brush and welding helmet. 

OPERATION

Working environment requirements



Only use the unit in areas that are well ventilated, free from dust, moisture and vapours. 



Do not expose the unit to sunlight and/or rain. 



Ambient temperature: -10°C to 40°C at most 1000 m above the sea. 

Mains connection



  Check that the mains voltage corresponds to the rated voltage on the type plate. 



  The unit must be connected to the mains supply with a three core cable with phase conductor, neutral 

conductor and yellow-green conductor. 



  The unit must be connected to the mains supply via the power source with a residual current device 

and fuse. Connect the mains conductors to the unit’s terminal block for the input voltage. 



  Cables must only be replaced by qualified personnel. 



  Connect the earth clamp to the workpiece before welding and check that it makes good contact. 



  The power cord must not be longer than 2 metres. 



  The conductor cross-section and fuse sizes are shown in the table below.  



  The cable must be of the type 3 x 2.5 mm
