As a Purchasing Manager, I felt like I was being sold. I have bought everything to run a furniture factory for 7 years. I have bought everything needed for repairs and maintenance. I have bought three Lincoln welders. The big welders are a nightmare in a factory because unfortunately, there isn’t a 240 volt outlet all over the place. And even less access to 370/480. After a lot of research, I have found that 1/4” needs to be welded with a minimum of 110 amps heated. 140 amps will do a great job.
Liked & Subscribed, I'm a hobbyist with a little 110v Hobart and a lot to learn. Thankfully nothing I'm doing has life or death repercussions and it's really just me dabbling in trying to make cool stuff for around the house. Thanks for sharing with us.
I have the hobby Lincoln welder 110v 20 amp run 1/16 rods and have ran 3/16 like to said 6011 to 6013 then 7014 to 7018 common mild Flintweld 37 E 6016. 1/16 rods
yep root and multi pass with good prep, did 9mm thick steel with my cheap flux core welder and its structurally good. if i did a single pass id be able to break it over my knee lol.
Hi Mark, nice video, well I'dlike to have a small welder for my fifth wheel rv camper when I'm on the road, just in case I broke the frame somewhere. Can you suggest me a small 110v machine on amazon for my need? Usualy rv frame broke at the upper deck, where it's made of 2x6 in metal I think, those tube are empty. Thank for your help.
Mark, If when SMAW welding, I've got one workpiece clamped to ground, can I gloved-handed hold the other workpiece to the grounded piece with my left hand while using the stinger with my right hand WITHOUT receiving an electric shock?, IOW, would the heavy leather glove provide enough insulation to prevent zap-city? Love you vids!
I have done this, and have also been shocked. So with that said, just make sure you're not also holding/touching the ground piece, in other words do not complete the circuit. My mistake was accidentally touching off on the ground piece with my knee while I was paying attention to what I had in my hands, was a quick jolt but nothing that grabbed me, though it can be fatal especially when working with juicier welders. Good luck, stay safe, and please don't become MK Raiden and and turn into a human sparkler.
This is true with all methods of welding. Just a few things you must make sure when using flux on thicker steel. ALWAYS remove the flux after each weld pass. ALWAYS bevel anything over 3/16. ALWAYS use a wire rated for multiple passes, because some cheaper flux core wire is only rated for single pass. Using it for multiple passes will make the weld too hard and crack with heavy use. ALWAYS remove mill scale. And if possible on anything above 1/4" pre heat the pieces with a torch. I would do a test piece and bend test it as well. Not recommended to use an underpowered welder for structural jobs though. Weld.com has alot of great info on this
As a new welder you totaly nailed this subject , i had a hunch that a 200 amp machine can weld 1/2" plate so long as i do like 3 to 4 passes

Great 👍 now I’m gonna weld a building with my 90 amp
The exception to this general rule is with vertical up welding, this allows you to increase metal thickness relative to fixed welding parameters.
This was the best answer to this question that I've seen.

Thanks for a very straightforward Explanation!
You explain this best I ever saw. Thanks so much.
ok, i guess i got a lot more learning to do. Thank you Mark!!
Thanks for the help Mark
Thanks for this video. It really answered my question.
Thank you teacher ,old jimmy Aust
Great, Great, Great, Thank you Dave from Oz

Like being back in class!
Thanks for the video.. please which size of wire will i use to weld 10mm thickness plate?
.035 or .045, even smaller wire will work you will just need to feed more. The smaller the wire the faster the speed
thanks for sharing
God BLESS YOU
Very helpful Thankyou.
Very helpful thank you
Awesome
information !!!

Subbed!

Lincoln 140 MP. small, capable, around $1000.00.

like it, straight comments.
If you weld thicker stele, is penetration the same?
Can we just make one great big weld?
This hold true for flux core welders?

Does Flux cored make a difference? thanks
YES, fluxcore has very different characteristics than solid wire.

1st :)
Thank you!!
