1 "POWER" switch (NFB)
Turns the power supply on and off.
Turn it on and off from outside of the case.
The lever position at the time of tripping (means that
the switch is turned off automatically due to over-
current) is same as the off position.
2 Gas supply switch
Normally set it to the "WELD" side.
Switch it to the "CHECK" side when you would like
to check the gas flow rate.
3 Digital ammeter
Indicates welding current values during the welding.
(Displays an average current value measured during
the period of 0.4 second in amperes in increments of
1A)
Due to a rounding error, a resulting value may vary
within the range of ±1A.
As this ammeter is designed to display an average
current value measured during the period of 0.4 sec-
ond, it may not be able to follow the variation of cur-
rent quickly enough when the current changes
frequently during the pulse welding, etc.
Indicates an "Err" (error) mark in case of a trouble.

4 Set-value display
Indicates the set values*
frequency (Hz), pulse width(%), etc.
The unit display lamp changes according to the type
of indicated set values. (i.e. "A" is lit for current dis-
play.)
Depending on the "DETAIL" settings, it indicates the
"Output voltage".
Indicates an "Err" (error) number in case of a trou-
ble.

This is the information display area.
Indicates condition-setting items in letters.
Indicates error contents in letters in case of a trou-
ble.
6 Jog dial
This is a dial to carry out the function of a potentiom-
eter (setup of current and time).
For example, to set welding current to 125A, turn the
dial to the right (increase) or to the left (decrease)
until such a value is indicated (on the set-value dis-
play).
Note: Turning the jog dial without discretion may
result in the change of a set value for the item cur-
rently indicated on the LCD display.
Use the press button function of the jog dial in the
following situation.
In the reproduction, storage or details mode (See
item (9) in the right column.)
7 "MODE" selection button
Select a desired welding method (TIG, STICK or
SPOT).
8 "CRATER" selection button
* The button is effective when the "MODE" (7) is
set to "TIG".
Selects a desired crater control (OFF, ON or
REPEAT).
"PULSE" selection button
9
* The button is effective when the "MODE" (7) is
set to "TIG".
Specify pulse to be OFF or ON.
