Welding start-up
Welding start-up
sequence
The welding start-up sequence for CMT Twin is as follows:
Welding start-up sequence
1. Both wire electrodes move towards the workpiece
2. Both wire electrodes touch the workpiece
3. The lead wire electrode commences the welding process, while the trail wire electrode
moves away from the workpiece and waits for the start signal from the lead wire elec-
trode = welding start delay
4. Once the trail wire electrode receives the start signal, it then also starts the welding
process

NOTE! The welding start-up configured for CMT Twin is only available with char-
acteristics version V2.9.4. Refer to the "Checking the characteristics version" sec-
tion for instructions on how to check the characteristics version.

WARNING! If the equipment is used or tasks are carried out incorrectly, serious
injury or damage may result. All the work described below must only be carried
out by trained and qualified personnel. Do not carry out any of the work described
below until you have fully read and understood the following documents:
- these operating instructions
- all the operating instructions for the system components, especially the safe-
ty rules
CAUTION! The power sources must be switched on for the following work. This
poses a risk of injury and material damage due to:
- welding current
- unintentional ignition of an arc
- emerging wire electrodes
Until all work is completed, ensure that:
- welding is not initiated by any power source
- the wire electrodes are not fed out
NOTE! When welding using two processes (one pulse wire electrode, one CMT
wire electrode), the welding process begins with the wire electrode performing the
pulse process.
