Miller Matic 200
This is the feed wheels that feed
the wire into the lining.
The top feed wheel is in the open
position.
.030 is the size of the groove
on the feed wheel, meaning that
this should have .030 wire in the
Spool.
These Feed Wheels can be turned
around for different feed sizes. As you
can see on one side it has .030 on the
other is is .035. Whatever number is
facing OUT is the size you are using as
the wheel has two sets of grooves. It is
meant for you to be able to look into the
welder and see what size you are using
without having to take the wheel off.
Insure this
feed tip is not
so far back
that it
interrupts the
feed wheel.
You will put
gouges in the
feed wheel
(like you see
here if you
zoom in) and
this can
create feed
problems to
the gun.
Close this lid down on the wire
to allow the feed wheels to feed
the wire.
Lift this into place to lock the feed
wheels. You can turn this nob to
increase the pressure on the wire,
you should not need a lot of
pressure here if everything is
running correctly and clean.
This knob is what loosens the the feed
tip that feeds the wire through to the
Gun
This is the feed tip that will be
loosened along with the rest of
the gun and the hose that houses
the wire.
This is the size of the wire in
the spool. As you can see,
the wire is .035. in the
previous picture the feed
wheel was smaller than the
wire. This will cause the feed
wheel to make the wire
oblong and lead to broken
linings and tips.
This is an adapter that allows you to utilize a different gun on a
miller welder. If you have one of these, the gun isn't a miller and
or original to the welder. The reason for this adapter is the gas is
routed through the clear tube into the hose instead of through the
welder on the inside.
Liner that houses the wire
that travels through the
tube to the Gun. MOST
typical issue with feed
problems.
This is pretty much
what the tip of the gun
looks like right before
you take it apart.
This is what keeps the
sleeve around the tip in
place!
This is the tip. This is the only part
that should ever touch the feed wire
of the wire inside that enables you to
complete the circuit and to weld.
All Tips should be round, if this is oblong
or out of round it can cause you to get
sporadic welds and intermittent spark as
the wire will only weld if its in contact with
the metal tip to complete the circuit.
These are holes that enable the
gas to be fed into the tip to be
able to weld! Check these to be
sure they are clean and clear.
Insulator, this is what
keeps the wire from
touching anything else
other than the tip.
This is the feeder tip that will probably be the dirtiest of all of them. Keep this
clean and it will help to keep rust and dirt out of the liner and extend the life.
To test the liner, pull some wire out
and make a loop. Loop the wire
around your hand with the tube
straight out from the welder and
pull on the wire. If the wire is easy
to pull and you don't feel any
“noise” or feed back in the wire
when you pull... this is a good sign.
If its hard to pull or you feel
grinding or noise or feedback, this
is a good indication there is dirt,
rust or the liner has grooves inside
of it and needs to be replaced.

How to tell what year your
Miller Matic 200 was built.
If your Serial number is for
example JK5874521 Your
Welder was built in 1989
The easiest way to set up your welder for welding is to use this chart which is on the
inside cover of the welder near the wire spool.
Look for the metal thickness of what you want to weld, then utilize the corresponding
range/Voltage/wire speed to give you a good starting point, then fine tune.
If you get lost, Miller was kind enough to provide a guide as
to what each part is called! This is on the inside cover of
where the wire is fed.
