Lincoln Pro Mig 140, welding 1/4 steel
This was my first time using a mig machine. (SEE Updated 1/4 inch welding video: https://youtu.be/TmMyRhhCjcs )
I am used to gas oxy acet, stick, and tig.
This is a 120 volt machine and is not rated for up to 1/4 steel in one pass. If you need to weld that thick, first V out the 1/4 plate. Here I am trying to weld 1/4 in thick plate steel using .030 mild steel wire and 22 CFH 75% argon 25 % Co2 gas mix. You have to stay close to the metal and keep a steady speed. I am using the hottest ‘E’ setting and 5 FPS wire feed. This is not recommended, it is something I just tried.
I beveled both sides of the 1/4 inch plate and wire brushed the metal first. I am using a 12 AWG extension cord on a 20 amp breaker and welding this hot does trip the breaker, a lower setting is alright on a 20 amp.However the machine does not cut out like some others may do.

Hey Vince, i just bought the same exact unit from Lowes… "no box display" . It looks exactly the same on the inside i.e plastic drive system, no switches for spool gun. Are you still using it after all these yrs? Your vid answers alot of my questions on usability…i was more concerned about the quality of that drive system etc. Thx.
This things just SOUNDS so much better than the starter flux core harbor freight model I bought lol…….
Flux core for me on 3/16 and up with a 180. Don't need much of a bevel, and probably don't need to bevel if I can get to both sides
Can you say “lack of fusion”, I knew you could.
Looks like a good little welder for around the home shop for little jobs. Maybe giving it a good preheat might help with the 1/4 inch plate.
Brother can you use an extension cord on this welders or you can damage it.
Buenos días, estoy seguro pero por favor me confirma ese equipo no es original de la marca lincon. Gracias por su reapueata.

Vince, there's a lot of good recommendations below in the comments and of course the usual, disrespectful know it alls, who are sneaking around with Mommy's computer. Here's what I recommend Sir, read and learn about H.A.Z.
Vince this stands for heat affected zone. This Sir will help you tremendously. Anyone can say and correctly by the way, there's no penetration, but understanding HAZ, will help you more than you'll know. Good luck, GOD BLESS, SARGE.
