3.4 Ground Connection
Plug the ground cable in the connector of the power unit.
Press in the plug and twist firmly clockwise.
The connection is not secured against working itself loose!
Check the plug connections regularly to ensure that they are
properly locked. In case of loose connection, heat may build up
in the plug and may destroy the entire plug connection.
Remove any rust, paint, or contaminants from the workpiece in the areas where
you intend to connect the ground cables.
Connect the ground clamps to the workpiece as securely as possible.
Take care to ensure good contact and symmetrical connection.
The welding location must lie directly between the two ground
clamps.
3.5 Change Working Place
Switch off the power unit. In this way, you avoid any risk of
electrical shock.
When you move your workplace, disconnect the welding gun and the ground
cables from the power unit. Proceed in reversed sequence as described in
sections 3.2, 3.3 and 3.4.
After changing the workplace, check the welding gun and the ground cables for
possible damage or missing components.
