The plasma cutting unit is equipped with a "Trafimector" (Fig. 4-2) for connecting the plasma torch. To connect a
suitable plasma torch, insert the plug of the torch into the corresponding plug-in coupling. Make sure that the
arrow of the plug is aligned with the groove of the plug coupling. Turn the plug half a turn to the right to secure it.
To release the torch, pull the safety catch at the beginning of the plug backwards and turn the torch half a turn to
the left.

Connection of the workpiece
ATTENTION:
Do not connect the earth clamp to the part of the material to be removed!!
In welding, the plasma cutting device must be connected to the workpiece via an earth clamp in order to obtain
the closed circuit required for welding. The workpiece clamp of the earth connection cable should be connected
in the immediate vicinity of the cutting point in order to achieve the highest possible degree of efficiency. Make
sure that the transition at the contact point is bare metal.
DANGER! Electrical voltage
Please make sure that the current cannot flow through chains of hoists, crane ropes or other
electrically conductive parts. Ensure that the earth cable is connected to the workpiece as
close as possible to the welding location. Ground connections made at remote points reduce
efficiency and increase the risk of electric shock and „stray“ currents..
