what's up guys davendado here today with you with weld.com explaining the differences of a lincoln
precision tig 225 versus alien precision take 375 and obviously there are some big differences
and some not so big differences so i'll hop over and i'll show you those
so i will show you what the main difference is in between the 375 and the 225 so 375 we have quite a
few knobs switches here the 225 only has three knobs this one ac balance the pulse frequency
and the post flow and of course your main amperage however on the 375 we have quite a few more and
i will show you what each and every one of them do first we need to make sure that it is on tig
welding mode and not stick then the next switch is minimum output and that controls on how low
your arc will actually start and if you move the display switch you can see and you can adjust that
setting otherwise that display switch will show normal amperage remote is foot pedal setting
obviously our maximum output and then our post flow setting i'll be setting my gas to about 33
cfh first will be the ac balance knob which controls the ac current so we don't really need
it because we are on dc negative to weld stainless steel to begin with we will be on two-step mode
for a foot pedal our pulse will be on there's off and there is on and you can see how the
light indicates the speed of the pulse so if you crank it way up it flashes real fast
it's actually how fast the amperage is adjusting on time sixty percent background is 40 down slope
and post flow is there at about ten let's first begin by setting the main amperage to about
170 160 ish and then we don't really need the penetration that's ac balance um it is on two step
we're going to turn the pulser on and here the flashing light shows on how fast it is
actually pulsing here the pulse frequency knob is how we change how fast that pulse pulses
as it turned down that light turns way down slows way down that's about where i'm gonna leave it on
time switch is how long that pulse is at the peak of that pulse the hottest time so do 60 percent
the background current peak is about how much amperage of your total amperage will be on
at the low end downslope we don't need the down slope don't like the downslope
and postflow i always run it about 10 seconds or greater just to ensure
that the tungsten is nice and clean and protected as it cools off again we are on dc negative
so today i'll be using a ck worldwide flex lock torch
it is by far my favorite torch because it is super handy you can get it in any tight space
with the swivel feature super ergonomical you can see how well it fits in my hand um right here
i don't know i've there's just been no spot i haven't really really been able to get it in
and then here's the tungsten i'll be using today this is a 332
two percent lengthenated or a blue tungsten
a number eight cup with a gas lens on it not a standard collet body
any collet but this is a gas lens which really helps the gas flow much much better
i'll be using two little squares of 304 stainless steel with 316 filler rod
i'll throw a couple tacks on here and then kind of go from there oh okay okay
apparently i am not perfect like anybody else so wow just wow decide to stick it
take it for a nice swim but i'll smash it back down to make it nice flat again
hey there we go all right i got my two blocks of stainless tacked up and i like to tack it in that
particular way that we have more areas to weld there's six places to weld if you look at both
sides and so here we go i will show you what it looks like now remember this is the pulse feature
so why this is why you see the flashing light it's not my foot control all the machine doing that
remember that little tiny green flashing light and that setting i had set that's what you see here
waiting for the post flow to cool down the weld and protect it as well as to protect the tungsten
from getting any contaminants or too many oxides and there it is
nothing special but there's a good example of how it runs especially on the pulse setting
and here you go so i welded the other side of it just to give you a little bit better view
of it nothing crazy now let's switch things up a little bit and let's start welding aluminum
so here we have the main polarity switch we need to switch it to
ac ac balance is set to 70-ish percent so we have quarter inch 316 aluminum uh 50 series
that's what it appears to be i set the welder right on over here
i set it to ac i've got no pulse so it is just going to be a straight current on ac
right here is the balance switch and i've got it set to about 70 percent on the negative side
inside about 70 which is going to allow me a good amount of cleaning but not too much
whoa
as you can see a little bit of trouble right here not too bad but it was just a little bit dirty so
i think the oxide layer off you know aluminum i'm just gonna give it a quick brush the wire brush
there we are nice and clean nice and clean now we'll go ahead and do a weld out pulse so just be
regular old ac 60 hertz because it's transformer machine that's why it weighs over 500 pounds
so
you can really tell and listen to this part
you can really tell the difference when there's no pulsar on or active
so
super hot i also wanted to show you the difference of changing the ac balance knob so here you see
the first weld on the left hand side i set it to 70 percent e in so good amount of cleaning but
not too much where far right side is 50 so it is the knob would be straight up and down at balanced
and way too much cleaning it destroys the tungsten it blows it off it's why that is so dirty
and you can actually see a hole underneath that weld because it didn't get enough
penetration where the center one is on auto that would be the green
area on the lincoln precision tig 375 ac balance knob that's where the machine thinks it knows it's
best and it does its own thing and you just sit down and weld preferably i don't like running
on auto because i don't like the outcome of it however i understand some other people may
so just to recap the lincoln precision take 375 versus the lincoln precision tick 225 really
doesn't have too many differences the 225 only has the three knobs which is the ac balance the pulse
frequency and the post flow on top of the main amperage of course where the 375 has many more
switches the ac balance the two-step forcep pulse frequency on time background current percentage
down slope post flow there's many more adjustments for the 375. also the biggest difference would be
the 375 maxes out at about 420 amps where the 225 is right there in about the 225 230 amps thanks
