MIG Welding Wire Thickness Table for Structural Steel Material: Optimal Current Settings

Hello, I have a request. Does anyone have some tables or he would be able to specify what thick wire is best to weld, given the thickness of the material and what current should be used for this (I mean ordinary structural steel). I will add that for me it is a wire for a migomat. Thank you in advance and happy holidays.

Hello .
My friend, I only found a table like this, maybe it will help you.
During the MAG-135 course, they said that the wire thickness must be adjusted by trial and error. I use 1.2 wire.
With my work, it would be difficult to change the wire every now and then, because we use Migomats for various maintenance repairs in the plant.
You have this table here. The quality is not first-rate because I took a picture with the camera from the book

I think jero badly pasted a large size photo at this address

Thanks for the answer and I still have questions about what that means in this table "I, V, X". And if someone else has more current because my migomat in continuous operation has 300A (EPVC 300 bestseller, maybe someone knows this device because I would need a schematic diagram or some hints because I have a broken cable and I do not know what it is for)

In short, I elements joined face to face, V elements chamfered on one side, after sliding together, a gap in this shape is formed, X elements chamfered on both sides clarification j w. This allows for welding thicker elements with more welds.

You write that your migomat in continuous operation has 300A, its name shows that it is up to 300A and this is its largest current. During welding you rarely reach such currents, I do not know what you would have to weld to use the current up to 300A.
After all, you do not have to use its power to the end, you can, as a colleague wrote above, weld thicker elements with more welds.

Maybe I will not use such a current, but I prefer to know in advance, if you really need to weld something thick, what to use (if necessary, buy) wire. And this migomat has 300A in continuous operation (as it is written on the rating plate), and in fact, you can probably get a lot more out of it because the feeder has a max load current of 640A. I would like to add that the entire Migomat weighs 285 kg and has dimensions
100/60 / 70cm (it is quite old equipment, and it was known in the past that decent equipment with a large reserve of power was made)

Hello and I have one more question. What kind of wire do you use to weld some steel constructions from sections, profiles, pipes, etc. with a wall thickness of about 2-4mm. Is 1mm wire enough or would you need 1.2. Because you know theory is one thing and in practice it is another. And what company do you recommend such a wire that is relatively cheap and good

Thanks a lot "Akrzy74" that's what it meant for me
