Tr 52Mc Remote Control Pedal Unit - Fronius MagicWave 2600 Bedienungsanleitung

OPERATING MODE: Regulation of pulse current I
TR 52mc remote-control pedal unit
- It is particularly advantageous with manual TIG welding in
cases where it is necessary to alter the welding pulse current
during the welding operation. (Where the welder is dealing
with materials of different strengths, for example).
- Link the connecting socket

the remote control cable.
- A remote control cable of the same type may be used for
linking the remote-control pulsing unit (socket

Due to the fact that workpie-
ces are often awkwardly
shaped, it is often necessary
to alter the amperage in the
course of the welding operati-
on. (e.g. repairing the edges
of tools, improvements to cut-
ting dies).
