Examples for various earth connections and possible effects:
Balanced earth connection
Ideal condition: The stud is located in
the centre of both earth connections
Unbalanced earth connection
Arc is deflected to the side where
there is less current density
Additional masses disturb arc

5.1.7 Connection of stud welding gun
• Connect welding cable of welding gun to the welding cable socket and lock it by turning to the right
until stop.
• Insert control cable into control cable connection and tighten with sleeve nut.
• Please also refer to the information given in the operating instructions for the welding guns.
5.1.8 Mains supply
• Compare the power data (supply voltage / current consumption) on the type plate with the data
(supply voltage / fuse protection) of your power supply network.
Always comply with the correct supply voltage as indicated on the type plate. Never
connect the stud welder to a power supply with the wrong supply voltage.
• Connect mains cable (item 13, chapter 5.1) to power supply using the CEE plug (standard 3 x
400V~, 32A-CEE plug).
DANGER
Only connect stud welder to approved CEE sockets.
Standard connection = 3 x 400 V + protective earth conductor. If need be, have an
expert in electrics check if the socket is earthed.
