Questions on spray mode

admin

Hello all just had some questions on spray mode and I was wondering if you can get into spray mode using 7525 shielding gas and also not really sure when the machine gets into spray mode I've heard that spray mode is very quiet as opposed to Short circuit transfer
Reply:I wanted to provide a little more details on the equipment that I'm using I have a millermatic 200 and I'm running it at full output voltage setting is a six and I have the wire speed about halfways up
Reply:True spray transfer requires minimum 80% Argon gas, and works best with 90%+ argon.What you've heard about the sound is correct;  spray transfer has a "silent" hiss that is 99% crackle-free when dialed-in correctly.  Your machine is likely too under-powered.  There are both amperage and voltage thresholds that need to be attained for spray transfer.

Reply:The generally accepted wisdom is that you need at least 80% argon to go into true spray mode. There are people who dispute that however. But in general, I am going to say no, no spray with 75/25. You might get close or into globular transfer mode. And yes, spray mode is a quiet "whooshing" sound with the occasional snap, crackle or pop.Miller Multimatic 255
Reply:What about 100% co2I’m using some Lincoln Ultracore 71c dual shield .045 wire in my Suitcase MIG and it requires 100% CO2. It sure acts like spray transfer..Miller Trailblazer Pro 350DMiller Suitcase MIGMiller Spectrum 2050Miller Syncrowave 250DXLincoln 210MP
