Fronius TransTig 1700 Operating Instructions And Spare Parts List

4
e) Manual electrode welding
- LED indicator (5) lights up and the digital voltmeter indicates the open-circuit
voltage.
- The welding characteristics are governed by the values for ARC FORCE and
HOT-START which are fixed in the machine itself.
- It is possible to influence these parameters from outside via the TPmc remote
control unit and the inert menue at function selector switch position
(5) LED indicator for manual electrode welding
- Select via function button (4)
- LED indicator (10) lights up (for main current I
H
) only at welding
- Welding current is present in the current socket [B]
- Welding current is either adjusted with the main current re-gulator (15), or via
the dial (34) on the TPmc remote control unit
(6) LED indicator for contact ignition
- Select via function button (4)
- Lights up together with either LED (7) or LED (8)
- To ignite the arc, touch the workpiece with the tungsten electrode after
pressing the torch trigger.
- The short-circuit current flowing when contact is made bet-ween the electrode
and the workpiece corresponds to the minimum current.
Where to use contact ignition: Whenever the HF used in contact-free ignition
would cause external interference.
(7) LED indicator for 4-step mode
(8) LED indicator for 2-step mode
(9) Starting current LED indicator I
S
- lights up when the starting current I
S
is active
(9) Starting current LED indicator I
S
- lights up when the starting current I
S
is active
(10) Main current LED indicator I
H
- lights up when the main current I
H
is active
(11) DOWN-SLOPE or current drop time
- For continuous adjustment of the current drop speed from the main current
down to the crater-fill current I
E
Range: 0,1 to 20 seconds
- When the Down-Slope potentiometer is used, the pre-set value will be indica-
ted for 3 seconds
e. g.: d S L 1.0
(12) Final current LED indicator I
E
- lights up when the final current I
E
is active
(13) LED indicator for TIG pulsed-arc welding
- As soon as the TIG pulsed-arc remote-control unit TR 50mc is connected up,
the LED (13) starts to flash (see the section headed “TIG pulsed-arc remote-
control unit TR 50mc”)
