Converting to single phase. Using the phantom leg technique --- or is it phantom limb technique
Reading a lot of posts about doing the conversion and finding this utube vid
Lincoln R3S-325 3ph To Single Phase Conversion w/capacitor - YouTube
pointed me in the right direction. I have converted the machine " Well " It at least turns on, I haven't tried to weld anything yet.
Hoping someone can explain my using an online calculator without understanding it's how and why's.
I have been playing around on online calculators, using different uf. 1st using a capacitor resistance calculator uf + 60Hz and " for the states" and 2nd inputting that resistance + 220v in the phase shift calculator. The different uf gives the same angle shift 45 ° and 155.56 voltage. But it does change the Currant/Amps, the larger the uf the more amps.
45uf = 58.9463R = 2.64A
50uf = 53.0516R = 2.93A
70uf = 37.894R = 4.11A

After installing a 50uf cap. I run different settings and recorded the amp readings.
Doing trigger pulls on a big chunk of car spindle.
This is the average amp numbers from different settings.
Using a high priced Harborfrieght clamp multimeter ($15.00)
L1 = 26.025
L2 = 25.725
L3 = 4.5
We can see L3 is way off from the others. When I plugin different size capacitors in the calculators, the closest numbers are 500uf = 5.3052 R == 29.32 A.
450uf = 5.8946 == 26.39 A
550uf = 4.8229 == 32.26 A
I also noticed. If I play with the resistance value "I.E" increase / decrease the value different from what the Capacitor Impedance Calculator spits out in the Calculate RC series circuit. It will change the phase angle.
I have a 45uf cap. Next i will run the 50uf + 45uf in parallel, check if it follows what I learned from this, so far.
