Summary of the PMC = Pulse Multi Control
PMC process
PMC is a pulsed arc welding process with high-speed data processing, precise recording
of the process status and improved droplet detachment. Faster welding possible with a sta-
ble arc and even fusion penetration.
Summary of the LSC = Low Spatter Control
LSC / LSC Ad-
vanced process LSC is a new, low-spatter dip transfer arc process.
The current is reduced before breaking the short-circuit bridge; re-ignition takes place at
significantly lower welding current values.
LSC Advanced
The TPS 400i LSC ADV is required for the LSC Advanced process.
The TPS 400i LSC ADV accelerates the reduction in current and improves the LSC prop-
erties. The LSC Advanced process is predominantly used when the welding circuit induc-
tivity is higher.
Summary of Syn- SynchroPulse is available for all processes (standard/pulsed/LSC/PMC).
chroPulse weld- Due to the cyclical change of welding power between two operating points, SynchroPulse
ing achieves a flaking seam appearance and non-continuous heat input.
Summary of the CMT = Cold Metal Transfer
CMT process
A special CMT drive unit is required for the CMT process.
The reversing wire movement in the CMT process results in a droplet detachment with im-
proved dip transfer arc properties.
The advantages of the CMT process are as follows

-
30
Low heat input
Less spattering
Reduced emissions
High process stability
Joint welding, cladding and brazing – particularly in the case of high requirements in
terms of heat input and process stability
Welding on light-gauge sheet with minimal distortion
Special connections, such as copper, zinc, and steel/aluminium
