I'm looking at a few tigs and i was wondering what you guys that do a lot of ss and aluminum use? i don't plan on tiging any thing over 3/8 maybe a lil 1/4 and this econotig from miller supports 150 A at 15 VAC, at 20 % Duty Cycle. I have been using my friends dynasty 200 miller and its nice and all but out of my price range. thanks for any input.
oh and heres a link http://millerwelds.com/products/tig/econotig/

Honestly you will out grow the econotig quick , I would look into a nice used syncrowave , can can get a good deal for what your looking into spending on a new econo tig , I had one and sold it after about 2 months ,

 

Yeah i was looking at a new syncrowave at the local gas shops the other day. they said i could pick on up for a lil over 2K with torch, pedal and some other ****. I would rather get a new one, cause i don't want one that has a million hours on it. but i will look in to some used ones.

 

look on e-bay there is a lot of venders on there that ahve them cheaper with free shipping also

 

not to thread jack but didnt feel like starting a new topic!

Im looking to buy a syncrowave 200 but there are a few questions before I buy that I would like answered...

I understand what ac and dc mean but whats better when welding or whcih is really needed? I see there is just dc (direct current) and then theres ac/dc?


There are also a few different models in voltage wise? 208/230,460/575
Now this would be used at home and I know that a special connector would have to be used to run 240v.... what would be recommended...

also last but no least there is single phase? and also 50-60 hertz with or w/o tig runner! what does that mean?

sound noobish I know, Normally when I weld i have someone setup the machine, well now I really want to learn and dont want to waste anytime probably going to pick up a welder within the month!

thanks for you advice and help!
Andre.

You may understand what AC and DC stand for but their meanings entirely different to know what they mean. To very basically tell you AC has to be used for welding Aluminum. DC has to be used for steels like stainless and mild steel. On the non-inverter machines like the syncorwave you can choose DC+ which is used for balling up tungsten if needed by the operator. DC- DC+ and AC can all be used for different Stick welding electrodes. Neither one is better just have different functions for different applications.

I would suggest getting an certified electrician to wire up the box and get the right plugs for you welder. Tell him what your doing and he should know what to do. For home use all you need is the 208/230.

also last but no least there is single phase? and also 50-60 hertz with or w/o tig runner! what does that mean?

I am no electrician but basically this machine needs single phase. To make it simple Hertz is a number of cycles used in AC. Tig runner is the cart that you can buy for the machine to set on.

Glad to see that you want to step it up and learn some more about welding. Next time somebody sets the machine up ask them why they are switching things over or PM me about any questions on anything.

If you can spend the money try and get the biggest syncrowave possible. This will help when you ever have to do some thicker Aluminum!

thanks for you advice and help!

Yeah definatley go with the syncrowave! You won't be dissapointed unless you try a Dynasty. The 20% duty cylce is horrible especially on AC. That will last like a minute until it shuts down. I have never used a econotig but I am sure that it is fine for very small shop type stuff.

 

do a quick search, this topic has been asked many times over the years
