Hello everyone and welcome to the X3M TIG channel guys so for today's video, I'm gonna show you
a couple tips and shortcuts on this 12-inch reducer sch.80. 12-inch reducer on a 12-inch 90.
so as you can see this is from my cross shift they did some the tacks some dogs to pull
that spool together is a little bit different from that fitting and from that reducer
there's not it's not even Gap all the way around so I'm just gonna grab a grinder open up
wherever it's tight I'm not gonna cut tacks I'm just gonna run one eight grinder
it is feather edge that's what I like I'm just gonna open up room make more room on top
and the bottom as long as I can wiggle one eight inside rod that's a pretty much good reference for
me okay that's what I did I clean it up a little bit all those marks from the dogs they used
and as you can see here there's a notch as I was re-beveling and opening up the top and the bottom
I'm not worried about it I'm gonna fix that later with the grinder, I'm gonna weld in between tacks
so pretty much the Gap is it's all right it's not even all the way around but it's uh it's way
better than what it was so I know it's a little bit time consuming especially in the field you
know, depends on the position here it's not too bad but uh don't be lazy grab a grinder open up
don't you know okay so 70s2 1/8 for the Root 125 amps I think that's pretty much the
that should be a good amp for this you can even go a little bit higher it all depends from your
travel speed and how much amps you can handle it's so the idea for this depends as I said
the Gap is not even so I'm gonna try lay the wire technique layer technique on this side
now keep the rod slightly inside as you can see here it's 70s2 especially when it's
your pipe it's not really properly clean from inside it's gonna be a little bit even harder
uh to manipulate to have a really good control over that puddle so try to maintain uh try to
maintain same steps same inclination try to keep the rod constantly connected to your puddle
you want to have a slightly little build-up on your root inside that's why it's really important
to keep it in the puddle and slightly inside inside root and and it's you know always
inclinations is changing guys depends it's not the same on one spot it's a
little bit different on the other spot it depends there's lots
of factors, your body positioning, your surroundings, everything you know obstacles
and the Gap is changing I like to go all the way to to the tack close as I can so
whenever it's tight it's easier for me just to change the technique I'm just gonna go
back feed technique on a horizontal same idea vertical horizontal the back feed is the
back feed keep the road inside and just just keep it in the puddle you gotta use the whole
length especially with the bigger diameter pipe just grab a whole length of your TIG wire and
just keep it connected keep it in the puddle as you can see here
the back feed even horizontal like especially with 70s2 it's it's a great idea especially because
we all know 7S- 2 that's specifically designed a rod for dirty applications like this
is one good example of that especially when it's not properly clean I'm pretty pretty much positive
that if they clean it inside properly I always like to go couple inches when I clean from inside
it'll be probably a little bit easier to manipulate but to have a control over that puddle
but it's not always ai deal that's the beauty of the field so just try to keep that Rod keep
it in a puddle if you lose connection just feed it back so just, just maintain you
know constant feed just run it through your fingers, keep it all the time connected
and stretch that puddle and you can see the build up here you know is you know
you got a lot of meat inside as I said I'm just going to weld uh close to the
tax I'm going to cut out the tax and I'm just gonna fix that the rest of that Bell
as as you can see here that's uh why why this road is really hard is all that all
those impurities are from the outside uh this is the root root looks good
especially for horizontal I mean uh horizontal is always prone to Sag down you know it's got
a more build up on the bottom as uh as the gravity and the gravity do that that work
that's why I always uh try to keep it on the top and stretch that paddle down so you connect both
edges but it's not a rule you know everything is always changing
everything is changes uh you can have one constant technique or one constant speed on the same joint
as I said uh lots of factors but play that role you know your body positioning uh obstacles
around your uh bye especially especially in the field how many times uh and it's one of
the most frustrating things uh when you want to scaffold it in the scaffolders they give you like
20 20 inch you know room between that scaffold tube and your joint and you're joined
I think a lot of us uh have that same experience and
but as you can see uh so I was doing labor then I was doing back feed and now I was holding from
the outside it all depends um so from the outside root I'm just gonna run a grinder
get rid of all those uh impurities all those uh it's like an even spots you know
they're one of the reason why it is uh that hard to manipulate that rod
and uh just keep it clean uh special for your hot pass hot pass should be
way way easier uh it shouldn't be any any much difference from a 70s6 rod
uh just uh Crank that hit I go back 160. for the Hat pass just gonna run beat one bit up and down
as long as you got a nice and clean surface uh below uh should be that should be good
and the good Heat and the amp is going to cover all those uh
uneven spots on your root pass and it's gonna keep it clean as you can see it's uh it's a big
difference from the root pass and from a hot pass way smoother way easier to control that puddle
I just gotta just keep that rod in the in the middle and just um stretch that paddle up and down
okay that's it pretty much uh this is for the for the hot pass as you can see it's nice and clean
uh just a good habit guys uh don't be lazy grab a grinder if you don't like it
just do a little touch up uh you know or a buffing wheel clean it up clean all your
passes so for the for the fill I'm just gonna go uh two two field passes for this welcome
procedure so I'm just gonna do one on the bottom one on the top it's just it doesn't really matter
you know it doesn't have to be in any order specific you can go one from the top first
and then on the bottom it's uh just uh whatever it's easier for you it doesn't really matter
you can wiggle you can walk the cup you can you can freehand uh whatever
you like you can use bigger cap you can always change uh the size of your cup
you know a bigger bevel wider bevel uh heavy balls heavy ball cup size 10 12 10 12 uh depends on the
how much you skip your uh tungsten all the sharp good uh good amperage a good travel speed
uh you should have a nice and clean uh Weld and that's the old idea you guys you got because now
you're prepping for the next welding procedure and that's going to be a stick in this case
and that's gonna be for the next video that's uh the most important thing keep it keep it nice keep
keep it clean the prep the prep is important you want to have a clear picture you want to clean it
and just keep it clean uh that's uh simple and for the next video I'm gonna show you guys how
to fill it up a little bit faster using a using a bigger rod it's gonna be a stick so I'm gonna
do fill and cap for a horizontal so if you guys interested you can check it out later and that's
it that's it for today's video thanks for watching guys uh and uh see you in the next one bye foreign
thank you
