    Stel P80 - 70A plasma cutter - 400V / 3-ph

    Don't ask me a bunch of questions! (Ruark, circa April 2022 )















    Look ma'! Twins! Shares the same exact case with the S300 stick welder/CAG.










    Next up is a CNC machine torch for it.

    Sweet...matching cases makes it easier to build a cart anyway...

    Nice look machine.
    It looks like everything you use is on 400 volts. Odd voltage for America, Canada or Mexico.

    Yep, I already finished my MIG cart, I just need to get the videos edited and put it together. I plan to build another cart for my Invertig 221 w/ water cooler, S300 w/ water cooler, Microcut 875sc plasma, Inverarc 200TLP stick welder. I'm not sure if I'm gonna put the P80 on the cart though, since I plan to use it for a CNC plasma table. Or I might just put it all on the new cart.

    It is odd because this machine is not meant for the western continents. It's predominantly meant for the European markets.

    It is odd to see 50hz 220v for a toaster or hair dryer. Try children sticking a paper clip in that plug.

    Back around the 1920's LA had 50hz and switch to 60hz. I new someone that had a job of change out the pulley on record players.

    I read somewhere some countries are going to 110volt 50hz for homes for add safety.

    American like 60 hz for electronics and little cheaper on generators.

    Ok... whole lotta question #1... does it use standard consumables or will they all have to be special ordered from Stel?

    Consumables are pretty standard. It uses the same torch as their now-discontinued 55A plasma cutter MicroCut 875sc, a Tecmo TH-70. The only difference is the cutting tips. The 70A tips are different, likely the orifice is just a smidge larger.

    So with a max. cut of 30 mm, that's just over an inch. That should keep you busy for a while...

    Yeap, right around 1+3/16" for a quality cut, with a severance of ~1+5/8" should keep me busy

    You need to post the quality cut at 1+3/16 Industry standards are 10 ipm at that thickness. I would think 1/2 that speed for that old torch design would be good pace..

    Half of Japan is 50Hz and the other half is 60Hz

    The story I heard is that when Japan was first starting to get electricity in the country one of the large cities bought their equipment from Westinghouse (or maybe GE) in the USA, while another city bought their equipment from a German manufacturer.

    Edit: Northern Japan is 50Hz and southern Japan is 60Hz

    1-3/16" clean cut is NICE.

    You can probably sever more than 1-5/8" depending on the shape of the part.

    I've cut 1-1/2" thick round bar with my 50A plasma that's advertised at 3/4" severance

    It's an Amico CUT-50HF. It's one of the cheaper models off of Amazon.

    I did it when I first got the plasma cutter, just to see what it'd do. Mightve been 1-1/4", but I'm pretty sure it was 1-1/2".

    Edit: I'll see if I can do it again.

    The display on the plasma cutter actually goes to 51 amps, so maybe that's the difference.

    By the way, just so I don't get accused of being a liar, I just came outside to the shop, grabbed some rusty 1-1/2" bar, clamped it over the burn barrel, and made some cuts. My big compressor is loud, so I'm using a little oil less one. Well, made the first severance cut (ugly). Decided to make a second prettier one to take a picture of. Well I done gone and either locked up the little compressor or maybe just overheated the contactor. (All good, I have other compressors). AND when the pressure dropped, I think I burned up my plasma electrode!

    Can't have nice things.... LOL

    Edit: popped one leg of a 50A 240 circuit. I forgot to tie the breakers together. OOPS. Compressor runs fine now. I checked the breaker AFTER taking the compressor all apart.... of course.

    I dont have steel that thick, but you could very well be right.

    Well, going off the pictures of your shop, it's either a Miller or a Fronius. You bought it used for $500, so I'm going Miller.

    Really my O/A torch is best over 1 inch in general.. Less issues, and it will be true of any air plasma. The 70 amp plasma cutters are a nice sweet spot for most CNC cutting.I liked my 120 amp single phase machines, but ended up with my 3 phase cutmaster 60i for it's $400 new price.. I went used for a old school Pakmaster 50 (35 amps), and was able to zero out the cost by selling on of the Sl-60 torches with it.(paid $150) I had a 40 amp SL-40 atc torch, and it was problematic on the 60i, and all the other machines I have used it on.. Found out by adapting it to the Pakmaster it's a fantastic combo, and has zero issues with that machine.. I can still run my SL-60 torch extensions, and torch on it, but The 20-35 amp nozzles are super low CFM, and put it in pancake capability..Although I have a 35c, and 15c built in compressor models The old school unit is a surprisingly good precision gouge unit with the SL-60 gouging nozzles. I know, because the had the Hypertherm 45XP, and Cutmaster 60i with dedicated modes, and parts.

    I am all for the old USA machines if you can adapt a bit better torch..

    It doesn't seem to matter if we're looking at the $200 versions or the $4k versions... they all put your fingers right beside the blast of molten metal.

    Need a plasma torch configured like an oxy-fuel torch. WAAY better control for longer freehand cuts too.

    At least move the button further back so you can keep your hand away from the work.
