Electrode welding:
 Connect electrode holder
Connect electrode holder as shown in the picture to the positive terminal.
Here, however, always follow the manufacturer's specification of the electrodes.
 Connection of work piece cable
When clamping the work piece into its holder, choose appropriate spot without paint or rust for good
conductivity.
 Start welding
Switch the machine to the electrode mode, adjust welding current for the welding task and start welding by
connecting the electrode to the work piece.
 Hotstart:
With the parameter ‘Hot start’ it is possible to set the current, with which the electrodes ignites.
This value can be adjusted from 0% (no increased ignition) to 100% (double ignition current) of the actual
welding current I1.
Arcforce:
With the ‚Arc Force‘ parameter a sticking of the electrode during welding can be prevented.
For this purpose, the welding current is temporarily increased.
This value can be adjusted from 0% (no increased current) to 100% (double current) of the actual welding
current I1.

A fairly approximate indication of the average current to use in the welding of electrodes for ordinary steel is
given by the following formula:
I = 50 x (Øe - 1 )
where: I = intensity of the welding current
Øe = electrode diameter
Example: for electrode diameter 4 mm
I = 50 x (4 -1 ) = 50 x 3 = 150A
NOTE: It's always the details of the electrode manufacturer must be observed!
