Hi all,
Need some help/advice from anyone who has either tried this or has engineering knowledge in the subject matter. According to several texts that I have read, Spray transfer mode can be achieve at voltage settings above 24 volts, provided the correct shielding gas mixture, wire type & diameter and WFS is used. The Lincoln MP210 is capable of a max 25 volts and 500 ipm WFS
I connected Lincoln tech support/engineering apps but they were somewhat uncooperative, recommended that I used/buy a different machine ;-) due to the limited duty cycle of the MP210 for this particular application. I'm not too worried about duty cycle because I'm only making 5" test welds on coupons for class work, so no rush to output lots of welds, in worse case I work on some paperwork or correct papers while I wait.
What I need to know, is what parameters will get me the closest to spray transfer mode using my Lincoln MP210 machine, which theoretically it is capable of for very short spurts of spray transfer mode welding since it is possible to set the voltage above 24 volts.
Here are the parameters that I ask the Lincoln app/tech engineers to help me with:
(0) Base metal: 1/4" mild steel plate
(1) Voltage setting (24 v and above): Use 25 v (i.e. the max setting)
(2) Shielding gas, here are the choices as I understand it: (must use an Argon-rich shielding gas for spray transfer, min 80% Argon)
(a) C20 (least hot)
(b) C10 (most common)
(c) C8
(d) C2
(e) 98% Argon, 2% O2
(f) 95% Argon, 5% O2 (most hot)
Which option for #2 do you recommend, a,b,c,d,e,or f? given (0) & (1)
(3) Shielding Gas Flow Rate: Use 40 to 50 CFH
(a) 40 CFH
(b) 45 CFH
(c) 50 CFH
(d) Other? please specify
Which option for #3 do you recommend, a,b,c or d ? given (0), (1) & (2)
(4) Wire diameter using ER 70S-6 (smaller diameter may run hotter, thus achieve spray transfer mode)
(a) 0.035
(b) 0.030
(c) 0.025
(d) 0.023
(e) Other? please specify
Which option for #4 do you recommend, a,b,c, d or e?
(5) Wire Speed in ipm; Range ? ( 350 to 500)
(a) 500
(b) 450
(c) 400
(d) 375
(e) 350
(f) Other? please specify
Which option for #5 do you recommend, a,b,c,d,e,or f?
Using the physics behind this science, which combination of variable above will get us the closest to a spray transfer mode on my Lincoln MP210 power MIG machine?
Thanks in advance for your assistance in this matter,
I'm looking forward to your specific solution to this engineering challenge.
