I'm shopping for a new tig welder for my home/hobby. I have no tig
experience, but would like to learn tig as well as be able to weld
aluminum and stainless.
It seems that I've reached an impasse trying to decide between a
transformer unit and an inverter unit. The available electric service
in my house limits me to 220v single phase approx. 50 amps.
Apart from weight, what advantages do the inverter units have over the
transformer units? I need to decide if it justifies the $1000 increase
in price.
For transformer units I was looking at the miller syncrowave 200 and
lincoln precision tig 225, which are within a few dollars of each
other.
For inverters I was looking at the miller dynasty 200 and the lincoln
invertec v-205t.
Any advice will be appreciated.
Mike M.

Hey Mike,
Others might correct me, but I don't think you'll be able to TIG aluminum
with the Inverter units. They are DC only.
Also, I think the reasons people like inverter units are that they are light
weight (i.e. more portable) and more efficient. If someone has to move
around a lot, the inverter would save their back. For a big corporation, an
inverter uses hardly any electricity when no one has an arc lit. I think the
transformer units have a lot more electrical waste whenever they are turned
on and just sitting there.
For your hobby usage, there probably would not be any benefit to spending
the extra on an inverter.
Now, someone on here will probably prove me wrong. :)

I have an Invertec 205. It seems to have it all: AC, pulse, variable
frequency, variable percentage positive/negative. Nice box.

I was faced with the EXACT same choice as you a year ago
If you will be doing any mobile welding the Dynasty is your best
choice the synchrowave is NON portable
otherwise if you have a dedicated work area with room for the
synchrowave then i can guarantee you both machines will make better
welds than a hobby user can so it leave the USER as the limiting
factor.
If youre welding mainly aluminum you will be able to dial the dynasty
in to far closer to ideal welds once you figure it out but that will
likely be a long ime after you get to welding aluminum
IN my case i weld some aluminum and lots of stainless in a dedicated
area
So the strength of the AC features was not nearly as important as the
Presence of Squarewave AC so the extra $1500 to 2000 for the machine
and accessories (torch pedal clamp, stinger regulator) for the dynasty
was not worth it
I went with a sync 200 and have loved working with it since
Remember that the price of a dynasty is JUST for the machine but the
price for the sychrowave is for a pedal ($200) a weldcraft WP17 torch
($125) an argon regulator ($125) and a ground clamp and stinger ($50)
so if you re buying a full welding rig the dynasty needs another $500
of parts on top of the machine price before its usable
2 last things i guarantee my advice is worth what you paid for it ($0)
and all prices including the value of my advice was in canadian
dollars

Please log in for more thread options I bought the Miller Dynasty 200DX with the contractors kit and have never
regretted it. Its a great machine and very easy for the novice welder to
use. I am quite confident when they throw dirt on my face I will still be
glad I purchased it.
