6.7.2.18 F21: Maximum cooling fan operation
The cooling fan can be rotated at the maximum rotation speed at all time.
•
[ON]: The cooling fan rotates at the maximum rotation speed at all time. Even when it is set to [ON], ensure not to
exceed the specified duty cycle. (
2.1.4
-
Rated duty cycle)
•
[OFF]: The cooling fan rotates in a control mode (power-saving operation) due to the temperature detection inside the
welding power source.
This mode is effective in saving power consumption and preventing suction of extra powder dusts.
6.7.2.19 F22: SUS EX pulse switching
Two types of welding performances can be selected in pulse welding of stainless steel.
This function is available when WELDING METHOD is set to "DC" or "DC WAVE PULSE" and wire material is set to
"STAINLESS STEEL" or "STAINLESS FERRITE".
6.7.2.20 F23: Sleep mode switching time
When the welding power source is not operated for a fixed period of time, it can be turned into the sleep mode.
•
[0]: disables the function.
•
[1] to [10]: enables the function.
Set the transition time to the sleep mode in the range of 1 to 10. During the sleep mode, power consumption is reduced.
6.7.2.21 F24: Wire feeding speed setting
The welding current can be automatically set based on the wire feed speed.
•
[ON]: enables the function.
–
The welding power source is automatically set based on the wire feed speed.
–
Even when the welding mode is changed by the GAS menu, the welding current is automatically set based on the
set wire feed speed.
–
Each pressing the UNIT CHANGE key, the wire feed speed display and the welding current display switches
alternatively. Switch to the wire feed speed display, and set the feed speed in the unit of 3.9 IPM (0.1 m/min).
–
Switching to the welding current display can check the welding current value automatically set.
–
In using the welding power source in the automatic machine mode, refer to the following diagram for the
relationship of command voltage and the wire feed speed (when the internal function F4 (Auto/Semi-auto mode)
is used with the setting of Automatic machine 1 mode).

In the sleep mode, the dot at the first digit on the left/right
digital meters flashes. All the other displays on the
operation panel are turned OFF.
–
Any operation during the sleep mode restores the
condition to the previous state.
