6.10.2.12 F12: Current increase and decrease by double-clicking
This function sets the current increase or decrease value by double-clicking when the welding current is
increased or decreased by the torch switch operation. This function is available when the TORCH
CURRENT ADJUSTMENT key is set to "ON".
• Set the current increase/decrease value by double-clicking in the range of -100 to 100 A.
6.10.2.13 F13: Switchover of current adjustment oeration at Pulse ON
This function is enabled when both PULSE SELECT key and TORCH CURRENT AJUSTMENT key are
set "ON". The operation executed by clicking the torch switch is selected from the following options.
The setting at the shipment from our factory is "1"
• [1]: Changes the pulse current only without changing the base current by click operation.
• [2]: Changes both the pulse current and the base current by the same current value (set by F12 and F13) by
click operation.
6.10.2.14
F14: AC ratio
You can set the AC ratio in AC-DC TIG mode.
The AC ratio is set to 70% at the time of shipment.
• AC ratio setting range: 10% to 90%
6.10.2.15
F15: Switchover of cleaning width display
When setting the cleaning width, you can select either "EP ratio" or "Strength of cleaning action" as the value
to display on the right digital meter. When "EP ratio" is selected, the "%" LED of the unit LEDs is illuminated.
Also, the standard value is displayed on the left digital meter.
•
[ON]: Shows the EP ratio.
EP ratio setting range: 10 to 50% (AC waveform: Standard, Soft)
5 to 30% (AC waveform: Hard)
•
[OFF]: Displays the strength of cleaning action.
Setting range of strength of cleaning action: - 20 to 20 (AC waveform: Standard, Soft)
- 15 to 10 (AC waveform: Hard)
6.10.2.16
F16: Adjustment of pulse waveform
When the pulse is set to “ON”, the pulse welding waveform can be changed.
Setting Function name Contents
0 Standard pulse Switchover between pulse current and peak current is the fastest.
1 Soft pulse
Arc becomes softer than the standard pulse. Welding sound is reduced by
smoothing current change. When compared with the standard pulse of the
same average current, melting down is less likely to occur and is suitable for
welding a thin worksheet.
2 Output stable pulse
This is a stable pulse that easily maintains the average current of the pulse
current and the base current even if the pulse frequency is raised.
