Yeah,
The PT185 model is an AC/DC TIG unit, which means it can do aluminum TIG welding.
But a DC-only TIG welding unit has a much lower cost, if you're just doing steel, pipe, tubing, etc.
I mean, the difference between a $500 DC unit and a $1000 AC/DC unit is not that much more in price, even though that's double.
So, you might as well get the AC/DC unit while you're at it, especially if you think you may want to do aluminum at some point, even though AC TIG is a lot trickier. DC TIG is much like oxy-acetylane, so you'll probably do well with it quickly, as your other thread states you've done some of that.
And Everlast unit like the PT185 would probably be a good choice there in Ontario, since Everlast is marketed and supported there, without any additional import burdens. Oftentimes the PT185 is marketed without the foot pedal included, which will cost a bit more.
I initially bought a PT185 via Amazon, but then upgraded to a 210EXT while the PT185 was still enroute to me. But the US Everlast people were happy to redirect the shipment back to their warehouse, and send me the 210EXT, after a reasonable upcharge.
The 210EXT is really my first AC/DC TIG unit. I had a DC TIG unit previously, and used it a lot. But I finally wanted to do some aluminum.
I think the advanced features on a 210EXT are helpful to a newbie for aluminum. I mean, it may seem king of counterintuitive, since most people will recommend a simpler AC/DC TIG unit for a newbie to learn on. But I say, no! A more advanced AC/DC TIG unit is good to learn on and you won't outgrow it or even long for those advanced features. The Triangular waveform was especially helpful to me when doing lighter aluminum, early on. But, now, I suppose a PT185 DV (and I do utilize DV on the 210EXT) has enough features and adjustability for 99% of what I do.
So, yeah, PT185DV or a 210EXT would be great, especially since they're reasonably priced, proven performers, and well-supported in the Great North.
Please let us all know back here whatever you get and how you like it.
