F1: Standard/Extended cable mode)
*3: Two types of welding performances can be selected. (

)
*4: In the welding of DC low spattering, the following devices are necessary for wire feeder and welding torch. For details, refer to the
instruction manual of each device.
•
Wire feeder: CM-743U with voltage detection adaptor kit (K5975V00)
•
Welding torch: BT3500V-30 or BT3510V-30
*5: This mode is suitable for welding hard aluminum medium-thickness plates.
