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”)
