- Wire feed speed, voltage, and contact tip to work distance are 3 settings on a MIG machine that must be set perfectly to get a successful weld. In this video, David explains how to set each parameter depending on the material that you are welding.

I really learned a lot from this video! I’m a new hobby welder having problems with penetration and weld profile and this really helped! Thank you!!
That was the most informative and well articulated video on MIG parameters that I’ve ever seen. Bravo to the presenter! He knows how to properly convey the subject matter.
Glad it was helpful!
David I have recently got myself a mig welder but haven't used a mig in over 40 year's, so have been watching dozens of videos to try and refresh myself. But this video of yours has hit the nail on the head for me, your explanation was brilliant and perfectly explained, you have helped me out big time and for that I thank you.
David, I came upon your video again after about 9 months and when watching it a real lightbulb moment occurred!
When you were demonstrating increasing stickout and reducing amperage because of increased resistance due to increase in wire length and compensatory increase in voltage things started to click for me in understanding the concept.
For some reason I kept thinking that the electron flow was from the gun which made things difficult to wrap my head around. Your explanation was so helpful. Many thanks!
Great video, especially the voltage explanation as most TH-camrs don’t understand their correlation. 👍
David, your explanations were very detailed and appreciated. Thanks much for extending your knowledge. Very different from all the other videos on youtube. People with machines that only adjust amperage, voltage, and wire speed with analog dials can really benefit from your lesson. Well done and thanks again.
David thank you for posting this video, haven't used a mig welder in almost 40 years and have recently got myself one that is synergic. I only use flux core wire and I could not get my head around it at all, but after watching your video I have now finally got the hang of it, your explanation on wire speed/voltage is brilliant and has helped me out big time, again thank you.
Good job sir ❤
This was really helpful - I'm getting more and more comfortable with mig through practice, and I had noticed that I needed to change WFS and Voltage to get good welds... but didn't know the why behind it. This was really clear and will help me day to day. Thanks so much, great job.
Hello @alatron, we are glad to hear this was helpful!
Thanks very informatif.
A very good explanation, your video was effective and I learned something usefull that will help me figure out the optimum settings for my recently acquired MIG welder, my old one was simpler, - but not yet too late to learn a bit more.🙄
Stay safe, regards Niels.
Thanks.
For sharing very informative
Nicely explained!
Wow, this was a really good explanation! I've been MIG welding for years, but I'd never realized that amperage was controlled by wire feed speed, or that voltage controlled the arc length. I always used the chart inside my Hobart Handler 210, and adjusted wire feed speed until the weld looked & sounded good, but I never realized exactly what I was doing when I did that. This will make me a better welder, thanks!
I just did my first home weld job, and used the suggestions in the video. The weld was still ugly, but it will work. Thanks.
Thanks David! Am a little confused about increased arc length when increasing voltage settings. If one keeps the tip to workplace unchanged and increases the voltage how does the arc length change? Have to say voltage in welding is confusing to me
Thanks
Thx again David. Excellent video. I am still cofused about the effect of voltage on arc length. Why does the arc length increase with increased voltage? Does the wire burn off more of the length of the wire when the voltage is increased when the contact tip to workplace stays the same?
This is an excellent question. You are correct, that if everything stays the same (wire feed speed, contact tip to work distance) and the voltage is increased, the arc gets physically larger. To explain the reasoning for this requires more space than I can fit in a TH-cam comment. I'd recommend doing some additional research on effects of voltage on plasma length or check out @styropyro's channel.
Thx
Just to add to my reply. Having done a little more hobby welding since I first saw this video I must congratulate this fellow on giving and showing the very best video demonstrating the effects of amperage and voltage on the welding bead. When I first saw the video I didnt appreciate just what a gem it was until I really thought about what I was doing while mig welding. Many, many thanks
Great information
What was your voltage setting.....that matters too
In the video the voltage settings started at 15 volts and went up to 25 volts. Proper voltage always depends on wire diameter and wire feed speed.
Been watching a lot of welding videos. No one explains it like that, make so much more sense. I’m butt welding thin 22g . Very hard to not blow though. A friend said to turn the feed way up, because the feed can’t keep up with burn. It helped but made big welds. Is that over compensating? Also when I grind down the welds, I have pitting along the welds.
