Hi! Jody thanks for your tips I was Never very good at Mig but you are bringing up the reasons why I have not been good. I am really interested to learn more using Mig because in the fab shop mostly Im using Mig for root pass from 1/2″ to 36″ pipe carbon steel using Lencoln Power wave control technology, My problem is doing root pass for 2″ pipe standard in a position weld 5-G. Im always having troubles on top from 12:00 O’clock to 2:00 O’clock. is that subject of voltage and wire feed speed setting? Thanks I really appreciate your help God Bless.

Great videos. Excellent job of explaining the process of welding and the problems as well as how to correct those problems. I look forward to your emails each week.

Excellent lesson Jodie!!!

Great lesson.. Could you please give a little discussion on the fact that these MIG machines are called constant potential or constant voltage welders. Voltage in only changed by the Voltage Adjustment Knob.. As the previous commenter ask, is wire feed speed directly related to Amperage? If one wants to increase the penetration (Amperage) while welding 1/4″ material, is merely increasing wire feed speed, and not changing the voltage adjustment going to do it? Does stick-out have a direct effect on amperage? Thanks for you insight.. Martin

Jody I had a question in relation to the duty cycles, if I have a machine rated at 60% at 300.amps how many amps would I have to go lower to now have 100% duty cycle? Thanks love your videos your the bomb.

Depends on the machine. There should be a graph/chart in your machine’s manual that details the duty cycle capabilities of your particular machine.

Jody,your tutorials are excellent. I was Never very good at Mig but you are bringing up some of the reasons why I have not been good. However I do not undertake a lot of welding these days but watching your tutorials,they are making me pick up the torch to practice for fun! In the past, I used CO2 the majority of the time. Electric Arc and Carbon rod arc, which the latter is hotter were two that I used many years ago. I am now going to dust down those old welders and just for fun practice again and again. I have been experimenting with Tig during the last few months. You have helped me a lot with your tips on Tig welding. Please keep going you are I am sure, helping a massive amount of people all over the World. I trust that you get a lot of thank you’s.
Regards, Jim in the UK

Not sure of the proper name for the machine, but it was a Miller MIG. 2 piece machine with a push/pull gun with a 35′ lead. Welds steel or aluminum. The vendor swore it could weld 1mm thick metal using the pulse. Seems a bit of a stretch.

Hi Jody,
I think this site is probably the most informative site I have found on the Internet! You cover everything, let people know what each knob and setting does and makes it all understandable. I am wondering when MIG went to Voltage instead of Amps? Has it always been rated that way? I have a Lincoln 185 TIG and am looking at a MIG sometime in the future. I am just a garage welder but I love the discipline. Metal work is great therapy! Keep up the great work.
God Bless,
Mike

Hi Jody,
1) The etched surface in the ‘push/pull’ demonstration: At least one of the nuggets appeared to have a sharp transition between the weld nugget and the parent metal [lower middle]. I would have thought that indicated less than ideal penetration at that point, and that it did demonstrate a difference in the welds. Not so?
2) I’d still like more detail on the three main types of wire transfer, such as the relative voltages/feed speeds that accomplish the different types of transfer, and when (if ever) globular transfer is best used–plus a demonstration of the latter. Is spatter an indication of globular transfer?
3) Cleaning prep–I weld mainly aluminum, and have found that the level of cleanliness and even the microscopic structure of the surface of the metal are critical for good MIG welds.
4) On the subject of voltage and wire feed speed: Would you compare feed speed to setting the amperage?
Thanks. I thoroughly enjoy your ‘lessons’.
