How can you tell if you're in "spray transfer" mode ?? Is there a physical appearance, different sound, etc?
I have a Miller 252 and normally weld 3/16" mild steel. The recommended settings on the machine for .035 wire are 18.4 volts, 265 amps and these work fine. But is this yielding a "spray transfer" or "short circuit" ?? Oh, gas is 92%/8% which is in the acceptable range for spray transfer.
If I go online, the recommended settings are as follows but aren't even close to the recommended setting on the machine.Volts are much higher but amps much lower.
For "short circuit"
Wire Size & Wire Feed Speed:
.035" (0.9 mm) at 320-340 ipm
.045" (1.1 mm) at 160-175 ipm
Shielding Gas & Voltage Range:
CO2 21-22 Volts 75% Argon/25% CO2: 18-19 Volts
CO2 gas is economical and has deeper penetration on steel, but may be too hot for thin metal. 75% Argon / 25% CO2 is better on thin steels, has less spatter and better bead appearance.
Amperage Range:
160-170
For Spray transfer"
Wire Size & Wire Feed Speed:
.035" (0.9 mm) at 360-380 ipm
.045" (1.1 mm) at 185-195 ipm
Shielding Gas & Voltage Range:
98% Argon/2% O2: 24-25 Volts
Amperage Range:
180-190
