But even that will only work if the sensor is working and the system is designed so that the sensor signals shutdown before any component is above rated failure temps. There are a lot of factors that can effect that. And I doubt any company wants the thermal cutoff set too close to the duty cycle, which could cause nuisance shutdowns and customer complaints.

    The duty cycle rating is supposed to keep components from getting to unsafe temps in the first place. Electronic components can have drastically reduced life when operated above nominal temps. Capacitors, for example, have a rule of thumb of half the life expectancy for every 10*C increase in operating temp. So for example, say a certain capacitor won't outright fail until it reaches 105C. It would still have half the operating life if run at 90C vs. 80C. And 1/4 life compared to operating at 70C, etc. Heat kills electronics.

    And remember, duty cycle is a percent of 10 minutes, so low duty cycles can easily be exceeded even if you aren't welding continuously. If you weld for a minute, stop for a minute, weld for a minute, stop for a minute, weld for another minute, you've just exceeded a 25% duty cycle. Even though you had a minute of time between each minute of welding, you welded for three minutes out of the last 5. Even if you paused for the next five minutes you still are at 30% duty cycle for those ten minutes. If you only paused four minutes then welded for another minute, you would be at 40% duty cycle, as you've welded for four minutes out of the last ten.

    Just something to keep in mind.
    Good to point out, I’ll admit that I thought that the temp light/the machine somehow limited duty cycle via operation. I’ve never had it come on, but see nw that duty cycle isn’t necessarily related to the temp light.

    I’ll be more cognizant for how long I’ve welded, cumulatively, and be sure to observe proper rest periods.

    Yeah it’s a bummer about the machine failing, I definitely think it was a Cap that blew, sounded like a .22 shot. No magic smoke though. Hopefully I can get this resolved, just not have any luck with welders. My Everlast had a mysterious TIG problem, and this one is dead in the water.

    Harbor Freight won’t Guarantee it -purchased through an online retailer. Have to have Proof of Purchase in the Harbor Freight Network. Keep that in mind, if you go to purchase one.

    Tried to get to the boards to see if it was a bad capacitor, they’ve made it all but inaccessible. A billion screws, Cowlings, glued connections everywhere.. bah.

    So tommorow, I get to see who; if anyone will be able to repair it, and then if it’s going to be reasonable. Fun.
    That is a bummer man. Can I ask who you bought it from? I see Walmart is marketing them for bookoo bucks.

    2 machines that I had blow the main caps (infancy failure) gave of a ton of magic smoke. My whole garage was a cloud of white smoke

    Bought it from an Ebay tool retailer, new sealed in box. Expected Harbor Freight, who is not just the retailer but the manufacturer as well, to honor their guarantee with some* proof of purchase, and with enough circumstantial evidence that I purchased it new. But, foolish me(I was actually hedging my bets that it probably wouldn’t fail).

    No magic smoke, just a really loud pop, and a thrown breaker. Resulting in a non working welder. No display, indicator lights, fan, nada. Dead.

    Emailed them, got the response back today. Was thinking that they’d connect me with a service department, but just said we can send your problem to the branch manager responsible in your area, in the form of a store complaint.

    We’ll see how that goes, they’ll probably end up citing their fine print again.

    I still believe it’s a good deal for a complete AC/DC TIG/Stick Package, just be sure to purchase directly from Harbor Freight as the One year Guarantee is a large part of what makes it a good deal.

    If you don’t have a receipt from them, and/or it doesn’t show up in their computer you’ll be sent out the door with your broken welder.

    What about returning it to the Ebay seller? Ebay is pretty good about forcing a retailer to refund if the deal doesn't turn out as expected. Maybe mention that to the retailer.

    That Ebay seller should be able to return it to his local store for exchange. He might provide you a replacement for shipping cost alone.

    Did he make any sort of claim in his Ebay listing like 'new in box guaranteed to work'?

    Just an Update:

    After some back and forth with Harbor Freight, I was finally able to get another unit. Naturally any retail store is going to be a pain without proof of purchase *from their store*, but I was able to win the day after speaking with, and presenting my case to someone who actually had some actionable authority. My case was that they, the manufacturer of this product give a 1year risk free trial, and I had a proof of purchase(so what it was bought outside of their store, they still made money on the unit I had). The problem was obviously a manufacturing defect in materials, or workmanship. Ultimately this couldn’t be refuted by them.

    New unit works fine out of the box, hopefully I’ll get more than a month of service from her.

    Again, if you decide to buy one of these, buy it direct from Harbor Freight Tools, save your paper receipt, and elect to have a digital copy sent to you as well. If you have a problem under those conditions I’m sure you’ll be well taken care of. Otherwise, be prepared for a debacle.

    After having the problem I did, I’d suggest ponying up the extra dough for the extended warranty. I don’t say that lightly, as for most things I think it’s a scam to part consumers from more of their cash. In the case of the ProTig 200 it’s one of the few items I’d say definitely is worth it. The price for time protected isn’t all that much, and from my encounter they don’t have the smoothest technical support system, so a warranty swap is your best bet should something go wrong.

    I like the welder, and the price I payed for it. It packs a lot per dollar spent. Hopefully I just got a bad egg, and the early failure of my last unit isn’t indicitive of the quality of these welders in general.

    Re: Vulcan Pro-tig 200 thread

    Beginner here with Tig, few years experience with Mig. What size tank of Argon is best for a hobbiest? Does this welder work ok with argon/helium mixtures? I understand that may require a high frequency start?

    Also can anyone recommend brand/model/part numbers for recommended consumables - rod, electrodes, lenses, anything else I might need for mild steel and aluminum? I’m not looking to do anything exotic. Just learn Tig with the most forgiving/compatible stuff. Later I’ll branch out and experiment.

    Buy the biggest argon tank you can afford/move around. I have a 125cf bottle, it’s about to be swapped. Bigger bottles are cheaper per volume to fill, and they also hold more so you’ll be driving them to the gas store less.

    I have not tried AR/HE yet, but don’t think you’d have any problems running it, just like any other TIG machine.

    This machine does ONLY high frequency start, it is a necessity when it comes to aluminum, works well for steel, stainless etc too. Unless you’re working on something where HF interference is a problem, you’re good to go.

    Consumables go by torch size for TIG, the Vulcan comes with a 17 series torch, so any 17 series consumables, brand name, or generic will work

    Lots of info on selecting gear for TIG out there. Get a decent Auto darkening hood, some 2% lanthanated tungsten in 3/32” and 1/16”. Start watching videos, and reading threads. Practice what you see and read.

    Have fun!

    ^^^^What he said. It work fine with adding helium provided the argon is the majority. Too much helium and the arc has a hard time starting. This welder uses capacitor discharge for start and likes a dense gas for starting.

    I just put the 12.5 ft Vulcan torch and power cable on a Dynasty 350 DX.
