why MIG weld-m/c max-V just get spray

Hello all

I was left surprised yesterday.

These Oerlikon Citoline 300T MIG machines look big and solid machines. Yet I found the machine had to be at max voltage tap available (coarse-2, fine-7) to break into spray. By the time I'd wound-back the tweaked-up the wire feed speed to get the correct spray-cone, that weld condition proved useful at 292A 29.6V (my calibrated meter)

BTW - gas is Ar-15%CO2-2%O2 (thanks Randy Z.)

Anyway - my surprise is that the machine does not have a bit of "headroom" on the voltage.

Every other MIG machine I have used which has the power to break into spray has at least a couple of "fine-clicks" on the voltage of "headroom" when getting the spray condition (Kemppi, etc).

Anyone tell me the whys-and-wherefores about this?

Thanks Gunner. Re. MIG machine - thanks again, but shipping it across Atlantic, our UK industrial supply is 440V 3Ph, etc. makes it not doable? Rich
