    shouldn't be

    Can't speak specifically about the Hobart gun, but if V & WFS are correct, and the material is clean, and the technique is in the ballpark there will be little or no spatter as this is a spray transfer or pulse process.
    I run a 30A Miller from a generator in spray mode for site work and from a couple of different power sources in the shop for spray or pulse and the results are excellent.

      Agree with OB, running 4043 or 5356 straight argon spray mode should be 0 splatter, correct polarity ???

        Some machines don't have enough umph to run in spray mode so some splatter in short circuit is normal. I can't spray on mine but i can short circiut weld all day long. I had a big Miller at work that would spray and it was nice...Bob

          Make sure you are running electrode positive with your argon shield gas flow rate at 30 cfh. With a 5-15 degree push angle and a 5/8" tip to work distance even with short circuit most of the spatter should not stick to the part

            When welding Aloominum the things that DrIQ mentioned are CRITICAL, you can get away with a lot more on steel but AL requires all things to be just about perfect.
