Remote Control Operation; Tr 50Mc Remote Control Pulsing Unit - Fronius TransTig 1600 Bedienungsanleitung

1. Procedure
l
Access "Codelock level P2"
l
"Cod _?_" appears on the display
l
Enter the present code (on new machines, this is 321)
- Set the desired numbers with dial I
- Conform each numeral with button
- Repeat this procedure twice, until "Cod OFF" or "Cod ON"
appears on the display
From here, proceed as shown in:
2. Change and activate code
3. Deactivate code
2. Change and activate code
a.) Display reads „Cod OFF":
l
Using the torch trigger, switch to „Cod ON" (see Pt. 2b for
further instructions)
b.) Display reads „Cod ON":
l
Use function button
CYC (cycle) indicates how often the unit can be switched
on without the code having to be entered
l
Using the torch trigger, set the number of cycles
l
Press function button
display
l
Enter the new numerical code
- Enter 0-9/A-H using the torch trigger
- Confirm each numeral with function button
- Repeat this procedure twice, until all 3 digits of the new
code have been entered
l
Press the torch trigger
l
The display reads „Cod _-_"
l
Re-enter the new code, for control purposes:
- set the desired numerals with dial I
- confirm each numeral with button
- repeat this procedure twice, until the code has been
entered
- the third time you confirm, the code is automatically
stored in the memory
Note! If you enter the code incorrectly three times in a
row (ERR), the machine will automatically switch to
„LOC". You must switch the machine off and repeat the
entire procedure!
l
Machine is now ready for use
3. Deactivate code
l
Display reads „Cod ON"
l
Using the torch trigger, switch to „Cod OFF"
l
Press button to shift to „PRO"
l
To deactivate the present code, press the torch trigger
l
Machine is now ready for use
Important! From now on, the code is 321 again!
Machine start-up when codelock is activated:
l
Switch on at the master switch
asks you to enter the code number
l
Enter the first numeral of the combination using dial I
l
Confirm this numeral with function button
l
Repeat this procedure twice more
l
Machine is now ready for use

REMOTE CONTROL OPERATION

Remote control units are intended for use in situations where the
welding parameters must be set directly from the welding workpla-
ce. The remote control unit is connected electrically to the power
source by means of special cables 5 or 10 m in length.
The following types of remote control unit are available:
l
Manual electrode and TIG remote control unit ........ TPmc
l
TIG pulsed-arc remote control unit .......................... TR50mc
l
TIG spot-welding remote control unit ....................... TR51mc
l
TIG Remote-control pedal unit ................................ TR52mc

TR 50MC REMOTE CONTROL PULSING UNIT

Fig. 10 TR 50 mc remote control pulsing unit
Since a pre-set amperage is not always ideal for the entire duration
of a welding task, pulsating welding current is often used. For
example, when welding pipes in cramped conditions, a change in
amperage is often necessary. Should temperatures rise too high,
there is a danger that liquid metal will begin to drop from the welding
pool. Too low, and the workpiece material will not melt sufficiently.
A relatively low welding current (background current I
steep up-slope to a considerably higher value (pulse current I
drops again after a pre-set period (Duty-Cycle) to the basic setting
(background current I ), a process which repeats itself over and
2
over again.
During the welding process, small sections of the weld zone melt
and solidify quickly. Welding a seam using this method is thus
considerably easier to control.
This technique is also used when welding thin sheet metal. Each
fusion point overlaps the next, thus forming a neat and regular
seam. When the TIG pulsing technique is used when welding by
hand, the welding rod is applied at each current peak.
(Only possible in the lowest frequency range, i.e. 0,2 - 2 Hz).
Higher pulse frequencies are generally used in automatic welding
applications and serve mainly to stabilize the welding arc.
With the TR 50mc remote control pulsing unit two operational
modes are possible:
l
Regulation of impulse current I
l
Adjustment of impulse current I
