Digital ammeter
• Indicates welding current values during the weld-
ing. (Displays an average current value mea-
sured during the period of 0.4 second in
amperes.)
Due to a rounding error, a resulting value may
vary within the range of plus or minus 1A.
1
As this ammeter is designed to display an aver-
age current value measured during the period of
0.4 second, it may not be able to follow the varia-
tion of current quickly enough when the current
changes frequently during the pulse welding, etc.
• Indicates an "Err" (error) mark in case of a trou-
ble.
Set-value display
• Indicates the set
frequency (Hz), pulse width (%), AC balance (%),
DC ratio (%), welding voltage
2
• The unit display lamp changes according to the
type of indicated set values.
• Indicates an "Err" (error) number in case of a
trouble.
LCD display
• This is the information display area.
• Indicates condition-setting items in letters.
3
• Indicates error contents in letters in case of a
trouble.

Jog dial
• This is a dial to carry out the function of a potenti-
ometer (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 display).

Note: Turning the jog dial without discretion may
result in the change of a set value for the item
currently 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.)
"Weld conditions" selection button
5
Selects a required welding method (DC TIG, AC
TIG or MIX TIG).
"Crater control" selection button
Regarding the selected welding method, selects
the "absence, presence or repeat" of the crater
6
control, as well as the "spot" (arc spot welding).
The arc spot welding can be done only in the case
of "DC TIG" and "AC TIG" welding.
"Pulse" selection button
7
Regarding the selected welding method, selects
the absence or presence" of pulses.
"AC waveform" selection button
8
In case the AC welding method is selected, selects
an AC waveform (standard, hard or soft).
"Mote" selection button
Selects an operation "mode" of this product (weld-
ing, reproduction, storage, or details).
Welding: Can be used to set welding conditions
and conduct a welding operation.
9
Reproduction: Can be used to reproduce stored
welding conditions.
Storage: Can be used to store the present welding
condition.
Details: Can be used to change the factory-set
mode of this product.
*1: In the case of a welding voltage, indicates the welding
voltage (between output terminals of this product) during
the welding operation rather than the set value.
*2: See section "Operation" for how to display welding volt-
age.
