Thank you, I am talking with a guy that do the same than you for Selectarc actually ; Indeed when I asked him about stainless, it does not do it for Iron.
In the mean time many welders use it, so that may be difference between ideal theoretical situation and what is done, the Nickel rods are...
What is "innoculant" ? Could you precise what is your experience in repairing iron by welding please ? (it may be useful to put things into perspective, thank you)
Thank you for all that
I suppose it is leaning on the theoretical side , that is anyway interesting on the metallurgy part.
I did try 7018, it cannot be hammered easily to loose the tension, and it also melt deep in iron while making a really not good looking weld (may be I did not use the...
About "soaking iron in vinegar to soften the carbon" :
(sorry for the cranky comments)
"No advantage and only possible annoyances. In addition, I do not see myself soaking a 110 ton marine engine after complete disassembly and wait several days. In short, graphite is a carbon and electrodes...
I use discs for stainless steel 1.5 mm thick so we control exactly what we want to do, Otherwise I use a thick cutting disc if I wanted to dig a simple furrow and I do my cord. I avoid the grinding discs like the plague. And considering the price of the discs, I always use new ones for the...
here is an exchange from another forum, it cames after someone said he wet the iron with vinegar for a softening of carbon (?)
WItnessing and used technique from a French solderer :

Without TIG , for "small" welds/bolts - 6mm nut- , better use OA or 1,6 mm stick (I have some 6013 "cell" sticks, would be happy to have some real use of those spaghettis - I hod them as a pen , so they do not bend and stick too easily)
OA work better on galva ? (pure theoretical question as...
Yes I had close vision done at that purpose. But I chooses to have the focus a little farther (about 300mm while I did not measure) it allows me to see clearly anywhere in the shop, and for welding if I want absolutely to see from a shorter distance I add 0.5 or 1 dioptries "cheating glasses"...
This is my fixed shade, a 3M old model sold by Kemppi

No risk of arc eye as the inner plexi protects against UV. So indeed you can have a flash, but the effect disappear soon and you have zero scratching eyes at the end of the day.
Learned that recently, I was afraid of being flashed before. Also just the material of your correction glasses is...
I understand it is mostly a question of daily use.
Not really answering you as you are pro (pro)bably ;). I noticed however many pros using a pipeline type with an
Mmarc one lcd (that is really not expensive)
On view quality, I was said that with some thousand of rods under your belt you...
To get your mask down lay the rod on its side only the slag touch the piece, and no arc created, close the hood then and make the rod touch.
Or with a noodling mask use your second hand to keep the rod in place (and to start it, BTW, after closing the flip flap I go to the rod with finger)
A...

Hello,
I do not understand if those lights are enough to put the LCD "ON" (dark mode) or if the pics show what you see in a fixed shade 9 or 10 with those led lights around ? I suppose that as they are really near the piece the light is optimized. Is it enough to locate confortably with a fixed...
Hello, welcome to the forum .
DO you wear glasses ? progressive glasses ?
My case . Despite having a 120USD LCD helmet 1 1 1 1 Transparency is WAY less than with a fixed shade (I did read similar infos on threads where users of top class LCD witness that they are less transparent than the...
That is not a question of focus but the lens of the camera, (let's say it focus from 30cm to infinite) oblige you to be near the puddle so it have a good size in the video.
passive , # ? (11, 10 , etc ..?) focus regulation before the lens is installed I suppose ? I have a good camera I could put on a stand too (but my welding is not interesting enough, may be I should shoot myself to see what I do, posture wise ?)
