hey welcome to Welkom I want to do a comparison I mean this is kind of a two-part thing I'm gonna do
a couple of welds the first one both of them are going to be outside corner joints both of them
I'm going to lean exactly the same I'm gonna try to keep the two of them exactly the fit up
and everything and what we're doing is somebody had asked a question about a Harbor Freight wire
versus a lincoln wire both of them are gasless flux core so the two part is I want to I just
want to run both of them on this outside corner joint just to kind of look at art characteristics
and see how they run and and feel and react with this type of joint the second part of this series
I'm I intend to want to do a fill it weld I think that's been done before but I want to do a fill it
weld and cut and etch the samples I want to look at depth of fusion versus the weld itself so this
is kind of a two-part thing one outside corner one fill it one of them is just going to kind of
see and listen and watch the arc characteristics same machine the second part of it we want to cut
and etch and and look at things not so much grain structure but we want to look and see that depth
of fusion so let me get my gear on I'll be right back I'm getting ready to run this weld here you
know I've leaned this a little bit more for a camera perspective good weld it flat I just
it's a common joint configuration in the common use here we'd run this slightly downhill just to
kind of blend these two edges here it's a outside corner so my electrical stick out probably going
to be about 3/8 of an inch on this guestlist flux core wire somebody's going to ask well why are
you running gasps let's flux cored wire with a nozzle gee whiz that's the only way I can keep
my contact tip in this particular gun so to have the nozzle on there the nozzle serves no purpose
other than keeping the contact tip in there plus it insulates it in case I accidentally touch
something here so it's all good and I understand why if somebody would ask that but again this is
on this particular gun it's the only way to keep the contact tip attached so here we go
the first thing I noticed about this was this is the Harbor Freight wire he's running 19 volts
and 200 on the wire feed speed as far as the setting I thought that was pretty close the way
it was should have reacted normal spatter normal amount of smoke deposit I didn't want to go but
this off I was watching my edges here to make sure that we were catching both the edges for
the most part but the main thing that I noticed the wire was sitting here jumping around it's
not like it just came out smooth it's like I had a arc length that was going back and forth
I don't know why that is I pre tested this feed before I before I made the weld so I'm not sure
what that was all about let me change wires buff this off and we'll do a side-by-side comparison
we'll make the other wire or the other the other weld with the Lincoln MP 211 wire be right back
same joint same angle same everything I just want to again I'm I'm just looking
to see how it runs I'm looking at will buck them both off and compare
them I'll give you my take on it and we'll talk about it's insane
I don't think I need to say a word at this point about what's going on here
matter of fact then we'll stop right there I did have a little bit of a broken tack on the
bottom and it opened up some let me buff these both off I'll come back and we'll talk about it
here in just second be right back okay we have a comparison here of two different brands of a
gasless flux core wire and you're probably going to you're probably going to want to hear the
final result here and want me to make some wild determination and I'm not being funny and I don't
want to disappoint but I'm going to tell you take your pick seriously I see the same thing in both
wires and if I showed you zoomed in I'm mark here's I know we've welded on some other parts
and I told you I was just going to do an outside corner joint keep it consistent we've made other
test welds and welds for other videos on here if I just showed you certain parts like between here
and here one weld and here and here of another and how you pick you know can you do that it'd
be kind of hard you really kind of need to see it under the hood but what I specifically noticed on
both wires one was worse than the other one was the fact that we've got a small spool here it's
a two-pound spool and you have a lot of what we call cast where the wire if I just let this loose
I'd want to spring and go all over the place and I'm sure some of you have had that happen
and then you put it in your your gun and you're wondering why it's not feeding out very good and
I think this may have happened on both spools I don't know but I noticed both spools of wire had
this inconsistent arc length and I don't think it had anything to do with the settings we had
a good ground we had good joint configuration when it welded it welded like it's supposed to you know
the normal spatter and normal smoke both the weld profiles look essentially the same so therefore
I'm going to say hey good luck you know I mean there's other brands I think they're all I think
any brand that you get and the guestlist flux core is going to look like this it's going to
sound like this I'm not blaming either brand for the spooling or anything like that I'm just again
i'm remaining neutral you know from what i saw under the weld hood i thought that they ran real
similar i've run a fair amount of this on various machines lincoln machines eSAB machines miller 110
or the hundred and ten volt means I like doing it occasionally especially when I have some portable
thing to do at somebody's house and I don't have 220 and I don't want to haul a great big machine
out this works this works great so you know pick a brand be careful when you're unspooling your wire
that you don't get a what we call a burden a store let this thing go so it unspools because you may
see that again to review I can't answer the why this wasn't coming out nice and smooth because
I went through all the tensioning and my gun was nice and straight I had a good clean contact tip
in again if somebody's gonna mention or ask the question why are you doing this with the nozzle
on when it's gasless flux core it's because that's the only way that this contact tip will
stay attached to the gun is when it's threaded in and shouldered up by the nozzle so you know
I like them both one didn't feed near as well as the other one but again I you know you're getting
the same results and I'm not picking either one or showing you which one which the one that didn't
feed is good I think welded the weld looks better on it so the second part of this we will go in and
I want to grab two fresh spools of wire on my make sure that they're both feeding really good if they
continue to do that fine but I do want to look at depth of fusion so I'm gonna make a comparison on
two of these even though this is a non critical application if somebody wants to ask and they
were curious about depth of fusion I want to do to fill it welds I'm gonna cut them and polish
that grain structure a little bit I want to etch so that we can compare depth of fusion I doubt
you'll see very much of a difference to weigh one over another brand I don't know well it's a good
experiment though so again I hope this helps I hope we answered the question and thanks for
watching well calm make sure you subscribe to the videos new videos come out every Monday thank you
you
