    You don't understand power factor correction. Go learn about it and you'll see my point with the capacitor power supplies of the inverters. They draw substantially more while they're charging than what a tranny draws momentarily at peak. The way you guys talk about inverters, you think they're the holy grail of energy. But, they're not.
    Interesting response. I post an example that counters your statement in one of your previous posts ... QUOTE: "How is 200A different than 200A? Inverters have far lower duty cycles than transformer machines."
    My post talks about 200A machines and our response is to change the parameters and give me a condescending comment about how I need to learn something that you think I don't know.
    Well I learned one thing from this thread, not to listen to your attitude and BS anymore. Good night

    • Well guys, I bought a welder a couple of weeks ago, and I just sat down tonight and read the rest of this thread that I started a couple of months ago. Amazing.....10 pages of Bull**** and 3 or 4 helpful posts. Thanks for that...Stang.....jackass.

      Anyway, I bought a TA185.

      • There's no condescension in what I said. If you understood the higher prolonged current draw needed to charge the capacitors to change the power factor of the machine, you'd understand that there is no savings in over all current consumption. Transformers have higher peak current draw, but the RMS (KVA) is lower. I'm not saying inverters are bad either, they make a lot of sense. Actually, they make a lot of dollars for the companies producing them.

        Transformers have a nearly indefinite life span. Say Hobart Bro's, Miller, or Lincoln sells you a tranny machine today; You use that unit for the rest of your known life. It might have some control circuit problems from a cracked solder joint or maybe a dried out capacitor, but for the most part, that machine will work until we're all dead and gone and several generations have come and gone since. It's a device of common physics. Current in one side: current of different voltage and amperage out the other. Just needs a little controlling to dial it in to what you want it.

        Inverters are a different beast. They have multiple capacitors that need to be working in order to feed the transistors that make up the output stages of the power source. Those need yet more circuits of transistors to tell them how much and how often to switch the power from the power capacitors. All of these SS components are detrimentally affected by heat. Moving high currents creates lots of heat. Heat also stresses the board the circuits are printed on, thus increasing the probability of mechanical failure under normal operating conditions. These are easier to produce, ship, and store because they're lighter, and use less expensive components as a whole. Anyone who's looked at current copper prices knows what I'm talking about. These also have a much shorter expected service life. What this means, is that the company now has a shot at selling you another new welder sometime before you die. Sure, lots of people out grow their machines and upgrade, but then those used machines just took out another new sale. Inverters offer higher initial profit margins, less initial expenses in warehousing and distributing the products, and have a higher probability of designed obsolescence. All of this is GREAT for manufacturers.

        • riland 200 ac/dc

          just got my new 200 riland tig ,,green bird
          this is the first time i tiged ,,alum ,,it was a bit tricky ,,but alum is a beast to weld,, if you got no practice,,but the machine worked well ,,foot pedle is nice,,weld were clean and look dam good, compare to mig,,..i'm useing brown code tugston,,works good ..
          but the arc flame what ever you call it ,,how is it suppose to look like,,,
          is it more of a plasma cutting look ,,,or more distorted look,,don't know
          thanks
          bill

            I believe the answer to this question is YES, the machine is worth the money. I bought one recently. And am amazed beyond what i had expected from it. My machine is a 200 amp ac/dc with hf and pulse & came w/ the foot pedal(metal one),regulator & 200 amp torch and as my skill level is getting better with practice I am realizing the full potential of this machine. as a garage hobbyist it suits my needs just fine and then some. I paid 975. with no tax shipping included. straight up price to weld, less gas and wire. might i add i totally expected to be throwing wrenches out of frustration that it would under perform and just be a total joke and so far its done well. I am however always leary about what if this machine takes a crap on me because of the horror stories i have heard. But i guess thats the insecure feeling you get when saving money on something like this. If it lasts 10 years i will be happy with my purchase. If welding was my bread and butter i would not lay it all on the line without a brand name, thats for sure.

            • I bought the Riland USA tig200wse with foot pedal back in 2006-08 ish. I had a lot of trouble trying to follow the poorly written manual and hoping someone can provide a better option for learning the machine. I believe that I spoke with Jack Storts around that time and he was in the process of re-writing the manual for ease of use. I lost contact qith him due to moving a d the welder went on the back burner.
              I also wanted to know options for replacing the extremely large and bulky toech head with something that is smaller and has a more flexible cable for finer work. The one that it has is big, heavy and not very flexible. I also noticed the gas line hose is cracking around the fitting, so need to know what to use for replacement parts and such
              Any help you guys may be able to provide would be a great help.
              ​​help.
              Thanks a lot.
