Choice Description
V Disp Status
○
OFF
Any output voltage (values measured between output termi -
nals) cannot be indicated on the set-value display.\
ON
The welding current screen and the output voltage screen
appear on the LCD display alternately every time when press -
ing the “welding current” button of the welding-condition setting
button section.
In case the output voltage screen is shown on the display, the
set-value display indicates an output voltage during the welding
operation.
Welding current can be changed even if the LCD display shows
the output voltage screen.
DCTIG StartPolar
In the case of DC TIG welding, electrode polarity at start of arc
can be selected.
○
EN
Arc start method to set an electrode to the negative pole.
(Suitable for continuous welding.)
EP
Sets an electrode to the positive pole for a second at start of
arc to prevent the arc from climbing. (Suitable when tentative
welding is often required.)
Hot Cur Level
○
Low
Standard
High
a
a. In case of using a thin electrode, setting to “High” causes the electrode to wear out quickly.
For better arc start, the level of instantly-applied current at arc
start is selectable.
Crater End Type
The weld end method at crater control “Repeat” can be
selected.
○
Normal Terminates the welding by withdrawing a torch.
Torch switch
b
b. In case “torch switch” is selected, transition from crater current to welding current is delayed by 0.5 second when the torch
switch is turned off, but it is not an error.
Welding is terminated when the torch switch is turned on and
off within 0.5 second in the crater control mode.
E.L. ShortStatus
○
OFF
During the welding operation, the output continues even if an
electrode is short-circuited.
ON
During the welding operation, the output stops when an elec -
trode is short-circuited. (The gas post-flow continues to func -
tion as usual after termination of the output.)
Disp Hold Time
○
0.00 S
to
10.0 S
This is the time period to keep the display of an average cur -
rent value obtained between 2 seconds and 1 second before
termination of welding, at the time of the termination of welding.
[It can be set to between 0.05 and 10.05 in increments of 0.1
second.]
AC Arc Recovery
○
OFF
ON
c
c. In case “present” is selected, the high frequency wave is generated again if lack of arc occurs during the welding operation.
(Be careful when using a robot or automatic machine.)
In case the lack of arc is likely to occur during the AC TIG or
MIX TIG welding, select “present”, and the occurrence of such
an event can be prevented.
