Of course, one is solid, one is hollow.
Yeah mate I’m afraid it’s not correct.Of course, one is solid, one is hollow.
Self shielded .. reason i ask is i have been playing with a new set and my beads seem quite thin compared to when i was using my mates set ( gas shielded set up) . I could deliberatly lay too much steel down etc when he was showing me what not to do but cant replicate this on my set using flux cored electrode negative. I can lay a neat bead but looks a bit flat compared to what i have done on my mates set with him saying they were very good. Even slowing right down just makes the workpiece nearly go on meltdown .. i know my set will be different i just though frigging a bead up by say laying far too much steel down would be easier which is why i asked the question.. i think my mates is 1mm wire . Sorry for the long reply just confused why i cant run a bead thats too high/ fat etcSorry Woz, but you're wrong.
OP are you talking about gas shielded flux-cored wire or self shielded?
Deposition rate is much, much higher with a flux cored wire over the same diameter solid wire.
Not that you get any gas shielded wires in 0.8mm diameter.
But the 0.8mm Self Shielded ESAB Coreshield 8, is about 30% higher deposition per hour than a 0.8mm solid wire like OK Autrod 12.51.
Its all to do with the burn-off rate which is derived from the cross-sectional current density.

This was my way of thinking.Depends how you look at it.....a 15kg spool of solid will deposit 15kg of weld.........15 kg of cored will produce less than 15kg of weld (about 14% less)
FCW will deposit more Kg per hour providing you have the current to take advantage
0.8mm solid isnt used to give high deposition so you will probably not notice much difference.....especially as the smallest FCW is often 0.9mm....(I know 0.8mm is available but its rare)
Wow.Have I got the one and only chance to edit a Mods comment out.Every day’s a school day.
Having never tried F.C I sit (in the pub ) corrected.
I won’t do a sneaky one and edit my comments out.
....the major difference comes when you reach the limit for solid wire (1.2mm maybe 300 amps) and the weld starts to look "boiled"....
Flux cored gas shielded and especially metal cored gas shielded can carry higher amperage than their equivalent sized solid wire...someone (Richard i think) explained it earlier..whilst maintaining a good bead shape.....higher current means faster welding.....thats it reallyCould you please explain more. I read somewhere about current limits for diameters of wires, but I do not really remember what those limits practicaly means, and which values are for each diameter. On the other hand, there is a story about ESAB OK 12.50 (non coppered) that could be used up to 400A without any problem.
