Short and Spray Settings

admin

I have a new lincoln 216 mig welder and was wondering about spray and short settings. Inside the wire cover is gives you a setting for the thickness of the metal but I think it is the short setting as is very loud as I weld. Is there a chart for different settings for spray and short for the different thickness of metals. I would need one for the letter type settings as the 216 is not a numbered display. Thanks for the help]Lincoln PT 225 Tig

Reply:Since the question is tabled, what does it take to spray arc self shielded flux core wire? I’ve looked through 200 sites and have not found a straight answer. When I do find data it is for gas shielded flux core wire. Some of the wire manufactures hint that it can be done with self shielded wire, but no real specifics on voltage and current.
Reply:Drich,With that machine, you don't need to concern yourself too much with "spray settings".Besides that, I suspect you'd need a different gas mix (such as C8) rather than the more commonly used C25.You may want to do a search on "spray arc welding".You've got a good little welder there.  Learn to use it well within it's limitations and don't be so concerned about what it "can't do".Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:Ok, for Spray Transfer theres a few thing needed. 1) 90% argon mix gas with hight voltage usally 27 volts and up . 2) around 400 WFS (wire feed speed). Your Lincoln 216 will not do a true spray, but it will be a hot Short Arc. You probally have a 75/25 Argon/Co2 mix gas right now or 100% Co2. You MUST have 90/10 mix for this transfer. For the question on Spray Transfer with Self Shielded Flux Core, when you run proper WFS and Volts it will resemble Spray. All this Spray with solid or flux core depends on wire diameter, normal Spray Transfer is done with .045 and larger wire dia., because the smaller dia. wires have a hard time carrying the hight volts properly. But it can be done with smaller wire but may be rougher arc. Hope this helps!!! The fella with the Lincoln 216, you have purchased a great machine, it outs out a great arc on steel and Al. spool gun.welding instuctor
Reply:LBW&F, thanks for the reply. I’ve got the amps and heat turned all the way up. The arc is very, very soft, 0.035 and 0.045 wire, sounds like an air leak hiss, no spatter at all. Maybe 225 amp & 23-25 volts. If I’m not careful the arc will burn through 1/4 in T joint.

Reply:Thanks for the insite. I'm using the 75/25 mix. I plan on going to the 95/5 when this tank goes empty. I was just trying to get a nice looking weld with out all the splater balls. I have played with the wire speed some which helps. I'm working on the first project which is a welding table. I think everyone's first job is a welding table. As it will be the center of the welding area I want it to look nice.This is a great site with great people willing to lend a hand.]Lincoln PT 225 Tig
Reply:Going to a 95/5 mix is not going to help your spatter problems.  For short arc the C25 is your best option.  The 95/5 is a pulsed mig spray gas.Tweaking your volts(heat setting) and your WFS (amps) will reduce/eliminate the spatter.Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:You should have little to no spatter even in short circuit transfer. Typically, you are running to many volts or moving to fast if you are getting a lot of spatter that sticks in big globs. The area of your puddle trailing the arc will look really violent, like it's boiling. Your gun angle will also play into the equation. In my experiance if I'm getting to much spatter(like any that you cant just knock off with your welpers) I'll first slow down, then turn my volts down, then adjust my gun angle and push the weld more...In that order. This is all in general and there are many exceptions in my opinion. I'm sure someone will bring some of them up :-PYou will never achieve a true spray arc transfer with c25. someone explained once how it was impossible. Try 98/2(o2) or the 95/5 with .035 solid wire at 25.5v and 450ipm if you can go that high on your machine. Ive gotten decent results on a mm252 at those setting doing hot/cover passes on low pressure carbon pipe on rollers.

Reply:Drich,for the Lincoln PM215 to spray arc ( I bet the 216 is the same) you will need 98/2 gas (98% Argon / 2% oxygen). That machine will do it, but I never achieved satisfactory welds in spray with it. The duty cycle is too low, and it did not have a great wet out with the 98/2 gas. The 98/2 gas was the only gas I could get it to spray in. I could not achieve spray arc with the 92% argon/ 8% co2 gas. You described the arc on the 216 as soft, maybe they changed the inductance on this new machine. The 215 had more of a crisp arc, and runs the best with .035 wire in short arc. I had to use .030 wire for spray arc, because it barely had the volts to run the .035 in spray arc. I am just not a big fan of the 030 wire with that machine. The voltage tap will be maxed out and I think my WFS was in 400-450 imp range. Its been about 2 years since I ran the PM215 in spray. Since then I got a MM350P for that, and I just use the PM215 for short arc (it has a very nice short arc that is nice and crisp) for 1/8" metal and thinner. Anything above 1/8" I just use pulse spray with the 350P.
Reply:I hooked up the 98/2 after work today on the PM215. I had .030 loaded in there so I just used that and did not run it with .035.The Pm215 has 7 voltage taps and the are tapped A-G instead of 1-7. I not sure on the 216 how it is numbered But just so this is clear, tap A would be 1, and tap G would be 7.It would not spray on tap E (5). It was a globular transfer, no matter what IPM on the WFS.On tap F (6)  it would spray on about 450 ipm. .030 wireOn tap G (7) it would spray on about 500 ipm. .030 wireThe 400-450 ipm that I recommended above must have been for .035 wire.Hope that helps.If I remember correctly It will not spray .045 wire, and would spray the .035 wire on tap F and G.
Reply:Thanks for all the help. You guys really know your stuff. The one post was wanting me to make my tip a little shorter. Right now it is flush with the nozzel. That is the way it came from lincoln. What will this do for me?]Lincoln PT 225 Tig
