Finally i get a chance to answer a question to the group---
I asked this question about 2 months ago, and got lots of
answers.
The most complete one came from a Product Manager at Miller.
All folks who responded to my post, were pretty emphatic to get
at
least a 175amp unit. While this requires 220v, the increased
versatility and capability are worth it. The one advantage the
HH has
is the purge feature. It lets the shielding gas to the tip,
without
wasting 20ft <g> of wire out the tip.
The lowest price i found was at
This may not be the case now, nor do their prices include an
"economy" cart.

here it is:
Both units have a similar rating and can weld with the same
sizes and
types of wires.
The Handlers have a tapped transformer. The different voltage
output
at the different setting is close enough together so that you can
adjust the wire feed speed and your torch travel speed to give
you
good welds for different thicknesses of material.
The purge setting allows you to set your gas flow without feeding
wire. To do the same with the Millermatic, you can just release
the
tension arm on the idler roll, adjust your gas flow and then
reset the
tension arm.
With a tapped unit, you should not have anyone adjust the voltage
while you are welding.
The Millermatic has infinite voltage control so that you can more
finely adjust your voltage. It allows you to set a lower
voltage
which helps on very thin (like 24 gauge material). The voltage
knob
can also be adjusted while you are welding.
Both units have wire feed speed tracking to make it easier to
tune in
the wirefeed speed when you adjust the voltage. If you increase
the
voltage, the wire feed speed also increases automatically. No
other
manufactures have this feature.
The Millermatic has a more rugged cast Aluminum feedhead with a
dual
groove quick change feedroll. The Handler also has a dual
groove
drive roll but a screw needs to be removed and replaced when
changing
the feedroll around.
Both units have short circuit protection in case the tip is
shorted to
the work.
The Handler will shut down and you will then have to correct the
situation and go back to the unit and reset a circuit breaker.
The
Millermatic shuts down quicker and thus the tip is not usually
damaged. The Millermatic also resets just by resetting the
trigger
on the torch. That makes it easier to reset the unit in case
you are
under a car or up on a ladder.
The Handler is supplied with a sample of selfshielding flux cored
wire
and the Millermatic is supplied with a sample of solid wire which
will
require gas shielding.
Both units perform well and would give you years of fine
performance.
