<Relationship of wire diameter and welding current at aluminum welding (Reference)>
*1: Note that the "collective" voltage adjustment may not meet the appropriate condition if a mixing gas other than those
with the following mixing ratios is used.
*1-1: MAG gas: Argon (Ar) 80 % + Carbon dioxide (CO
2
)20 %
*1-2: MAG gas: Argon (Ar) 90 % + Carbon dioxide (CO
2
)10 %
*1-3: MIG gas (stainless steel): Argon(Ar) 98 % + Oxygen (O
2
)2 %
*1-4: MIG gas: Argon(Ar)97.5 % + Carbon oxygen (CO
2
)2.5 %
*1-5: MIG gas (Aluminum/Aluminum bronze/Silicon bronze): Argon (Ar)100 %
*2: Available for applications either of "STANDARD" or "HIGH".
*3: For "STANDARD" mode, the standard mode or extended cable mode (extended mode of power cable) is available.
(
-
F1: Standard/Extended cable mode)
*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: CMV-7402
• Welding torch: WT3500V-SD or WT3510V-SD
