Tr 52Mc Remote Control Pedal Unit - Fronius MAGIC WAVE 2600 FUZZY Mode D'emploi

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

Connecting the remote control unit:
- Link the connecting socket
socket on the remote-control unit electrically with the remote
control cable.
- Plug in the plug-in connections the right way round, and screw
the coupling ring on as far as possible.
Functional description:
- When the TR 52mc remote-control pedal unit is connected, the
.
machine automatically switches over to 2-step operation.

- The mean welding-current amperage is indicated on display A.
- No "Hold" function
- Gas pre-flow time and gas post-flow time are set directly at the
power source.
- To initiate the ignition process, gently step on the pedal.
- The level of the start arc current, the main current I
crater current can also be controlled from the pedal.
- When the welder takes his foot right off the pedal, the welding
current is switched off, thus interrupting the welding operation.
Gas post-flow time elapses.
Limitation of main current
If the maximum welding current value is set internally on the main
current I dial then the remote control pedal may be depressed
t
H
to its full extent without the main welding current exceeding the pre-
set value. This has the advantage that the selected current range
is covered by one complete depression of the foot pedal.

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 cutting
dies).
The TR52mc pedal remote-
control unit is designrd to be
used for jobs such as these.
