hi guys welcome back to world.com i'm michaela and today i'm going to be showing you the
difference between pulsed and non-pulsed tig welding
i'm using my miller destiny tig plant with pure argan shielding gas i've got my tig machine
set at 120 amps and on an ac current as i'm welding aluminium in my tig torch i have a
2.4 millimeter lanthanated tungsten it's with 2.4 millimeter esab 4043 aluminium filler
rod i'm using an edge glass cup for better viewing of the arc firstly using no pulse
means there is a consistent current so whatever your amps are set at like mine are set at
120 that is what will come out of the torch consistently this creates a soft world and
is really easy to add filler to
[Laughter] all the worlds i'm doing today i'm using an open corner joint as this is
the easiest way to see the difference between pulsed and non-pulsed tig welding some of
the reasons we use pulse welding is for when we're welding in difficult positions such
as overhead when gravity works against you pulse welding can help keep the whirlpool
above you it can also be used to help achieve that laying down dimes effect as it creates
a consistent world as long as your travel speeds the same all the way along and it can
also be used to go over ugly worlds to make them look nicer with pulse welding you operate
your tick machine exactly how you would before the only difference is a pulsed waveform will
come out the torch instead of a consistent one you use your foot pedal exactly the same
as you would for example backing off means less heat pushing down on the pedal heats
up more
the first pulse setting i'm going to show you is one pulse per second i'm going to tack
it together in an open corner joint and then fully weld it with no filler material all
my wires today i'm using 120 peak amps and this drops down to 30 amps whilst pulsing
[Music]
this is what the one pulse per second world looks like they're quite wide beads but it
does create a nice consistent world now i'm going to try it with the pulse per second
set at 2.5 [Music]
my
[Music] this is the 2.5 pulse per second world as you can see it's nice and consistent with
the one pulse per second and the 2.5 pulse per second these you can add filler rods to
really easily as you can time when you're going to add it but anything faster than 2.5
becomes quite hard to add filler rod to when using one pulse per second you can time when
to add the filler rod like this [Music]
so
[Music]
this is one pulse per second with filler rod and this is two pulses per second with filler
rod
i'm now going to turn it up from 2.5 to 10 and see how much a difference it makes
[Music] [Laughter] 10 pulses per second is a lot faster and harder to add filler wire
to but it has created a nice consistent world i've now changed the pps to a hundred
[Music]
when welding one pulse per second or 2.5 pulses per second you can time it just right to add
your filler rod when you go higher than 2.5 pulses per second it's much harder to add
filler rod to if your tick machine doesn't have a pulse setting then not to worry you
can use your foot pedal to pulse this is called manual pulsing when manually welding i put
my foot flat to the floor to get 120 amps then i lift it up almost all the way but not
off and repeat this process to create a pulse
[Music]
when manually pulse welding you're never going to get the same consistency as you would with
a proper pulse setting on a tig machine but it still does the trick of making nice welds
here we have all the different worlds i've done today we have no pulse which is a very
smooth world and you can't see any dimes in it
this was a consistent current at 120 amps we then have the one pulse per second which
create very long dimes but create a consistent world we then have 2.5 pulses per second which
is my favorite this creates the laying dimes effect and looks really good we then have
the 10 pulses per second where it's harder to see the dimes and is getting more like
a consistent world we then have the 100 pulse per second which looks like a consistent world
but is pulsed it creates a slightly thinner world than the consistent non-pulsed and finally
we have the manually pulse the manually pulsed is never going to be as consistent as it would
on a proper pulse tig setting but it does the job of creating a neat world
that's all from me i hope you enjoyed the video and thank you so much for watching
[Music]
you
