A CMT TWIN welding process requires a WF 60i TWIN Drive unit and a wire buf-
fer.
In conjunction with a WF 60i TWIN Drive unit, all TWIN characteristics ignite ac-
cording to the above sequence.

Both wire electrodes move towards the workpiece
Both wire electrodes make contact with the workpiece
The lead wire electrode starts the welding process, the trail wire electrode
moves away from the workpiece and waits for the start signal of the lead wire
electrode = welding start delay
As soon as the trail wire electrode receives the start signal, it also starts the
welding process
