AZZUNOAC/DC TIG Welder 200A with Pulse 110V/220V, Aluminum TIG Welding Machine, ACDC TIG/PULSE TIG/SPOT TIG/Stick Welder Machine

I have been welding 1/8" mild steel with this in 110v and it works pretty well for that task. The High Frequency Start works great. I own a few MIG welders but this is my first TIG welder so I don't have much to compare it to, but I'm very happy with this purchase so far. If it ever dies, I'll update in how long it lasted.

The worst thing is that there is no user manual and no video to guide the installation for the Azzuno Tig 200A Ac/dc. and Azzuno Mig 200F welding machines. Hopefully there will be a change to fix this weakness.

This welder is complete as far as functions, and performs in both TIG and stick modes admirably.It is one of a new wave of inverters from China that have engineered all the features you might want, into smaller packages that what was previously available.A useful but not exclusive feature is the addition of a dedicated "spot" or "cold spot" function which provides a timed burst of a set value welding current; great for thin metal or repetitive tack welds in general; this is in addition to the complete "pulse" functions provided.The single knob control panel is straightforward and easy to set.The unit is compact and sturdy..The machine is constructed using MOSFET as opposed to IGBT electrical switches, more unusual in the current market, but prevalent in the pas; the welding and electronics community debate the merits or lack thereof to no end. I have used weldes powered by MOSFET from both Italy and China, and had no negative issues, so you can read up on the technology, but in the end I feel iit is not a deciding factor in making a purchase.There is provision for an available, but not included, foot control, which is also something not often found in the smaller inverters of the past times.Unfortunately the connection for the torch, is not a standard set up using one panel connection for gas, and a separate dinse plug for current, but rather a combined connection that limits the use of other torched to those so configured.The dinse connections are the larger size, and in my opinion could have been reduced to the smaller size, especially considering that at full amps the duty cycle is reduced so that the chance of the smaller plugs being overburdened is unlikely, This would have given space for a sparate standard gas connection as well). The gas connection at the rear is also nonstandard, being a barbed male nipple; far better, again, to provide a standard gas hose connection and hose.As to the overall package, the gas hose provided is stiff, cheap and useless, so figure on sourcing replacement material. Even though the machine is 200 amp maximum, the torch included is overly large, and has the now obsolete design that has the trigger simply tie wrapped onto the handle, making for a awkward and cumbersome device, especially considering that most users are probably doing more precision and delicate work which would be benefited by a more compact and manuverable torch,The included flowguage, while welcome, is not set up for direct connection to USA tanks. There may be adapters available, but none is included, fortunately, I had a appropriate nipple and gland nut on hand, so removed and replaced the originals.Priced at $450USD with discount, this is not really the best deal for this style of machine. There is a different source machine available, with identical features, (including spot), which does not however include a regulator or flowgauge, but does include the footpedal, as well as having a standard rear gas connector with a standard gas hose of good quality with USA style brass connectors both ends. Additionally it comes equipped with a Euro style ergonomic torch of a more reasonable size. The machine does however still utilize the same nonstandard front torch connector, and has IGBT as opposed to MOSFET electronics.This package sells for $140USD less, so is a considerable value. I feel the manufacturer/ sales agents for the Annuzo machines should be aware of the competition and adjust their pricing and package contents to offer consumers a comparable value.

Works great and Good Quality

Great machine

Looks like a very well made machine, it's a shame to send it back because the owners manual is useless, This is not a good purchase if you are new to Tig welding,

Came without documentation, asking azzuno for it went unanswered web or otherwise. , flowmeter didn't fit my brand new argon bottle. No adapter either. Worthless , ordered new flowmeter since all this . I haven't been able to even try it outFrustrating! Comeon azzuno , make it right!Edit: the company did reach out to me with the documentation I requested. Then I was credited for the flowmeter having had to buy one that fit the bottle . Which was a really thoughtful surprise , and thank you Azzuno.

This is for the ACDC-200 (AC DC 200F) 110v/220v single/poly phase powered (in most of the US, this is 120v/240v) unit.I have just started playing with it. It is not a Miller but it does what a Miller (that costs 8x as much) will do. Though it is a light weight machine; no problem with 1/4" (0.250in) aluminum and even 3/8" (0.375in) but that is pretty much it, and I recommend investing in a water cooled torch if you plan on glueing aluminum together for any moderate period of time.Response is good, the torch is not the highest of quality but... it works fine (especially when considering the price).This is the ideal beginner's TIG welder. If you've been wanting to learn, burn a grand (this plus tank and fill, lots of fiddlybits, taxes and shipping), you won't regret it.I have not used it on steel yet.This light duty unit will reward you with pretty solid welds! I do not intend to run this thing for multiple hours per day, every day, and i have not done so, thus I cannot speak to how well it handles serious loads over longer periods. I look forward to others attempting to do so and reporting on their results :-)I have to give this 4 SOLID stars, because it is easily comparible to the ~$700-1700 tier tig welders.... while being a serious discount to them all... This means more budget for cups, electrods, ARGON tank + fill, etc..Seriously, this unit, with another ~350-400 bucks in gases and fiddlybits and you can legitimately well up almost anything.HIGHLY RECOMMENDED (if you are only using it for light duty jobs or learning)
