Summary of the PMC process
PMC (Pulse Multi Control) 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 stable arc and even fusion penetration.
Summary of the LSC / LSC Advanced process
LSC (Low Spatter Control)
LSC (Low Spatter Control) 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 properties.
The LSC Advanced process is predominantly used when the welding circuit
inductivity is higher.
Summary of SynchroPulse welding
SynchroPulse is available for all processes (standard/pulsed/LSC/PMC). Due to
the cyclical change of welding power between two operating points, SynchroPulse
achieves a flaking seam appearance and non-continuous heat input.
Summary of CMT process
A special CMT (Cold Metal Transfer) drive unit is required for the CMT process.
The reversing wire movement in the CMT process results in a droplet detachment
with improved dip transfer arc properties. The advantages of the CMT process are
as follows:

Description
The droplet increases in size on the end of the wire electrode and is trans-
ferred in the mid power range during the short circuit.
A short circuit-free transfer of material in the high-power range.
• Low heat input
• Less spattering
• Reduced emissions
• High process stability
