What model HT are you using that can sense material thickness?

Sent from my SM-G715U1 using TractorByNet mobile app
Not in the shop to look and it's too dam hot to go outside but the one I have I bought 10 years ago and it was over 6 grand. Like wit most things, you get what you pay for and that includes plasma cutters.

Although mine is red, it is the same model. I wouldn't get one that didn't have pilot arc. I'm not that good! www.uwelding.com is their website. Supposed to do up to 5/8", I know it will do up 1/2" from using mine. Never had to do heavier.
Can you drag with it? On Amazon, I think I read they don't offer drag tips.

Forgive my ignorance, but a Plasma Cutter sounds as useless as a Hot Water Heater. Why would you need to cut plasma?

Because not all plasma conduits are the same size. Sometimes you have to cut the plasma down to fit. Just like sending the smaller people into the Jeffries tubes.....

I have the Lotos with the pilot arc but don't remember the model number off the top of my head. A little bit of a learning curve but once you get the hang of it consumables last a lot longer. Considering the amount of stuff I have cut up with it over the years and the price of oxy/act. plus bottle rental it has paid for itself many times over. If it died tomorrow it wouldn't owe me anything. I think it was about $450 from NewEgg . com of all places. I couldn't justify the $$ of a big name unit and took a gamble on this one. Sometimes you win one.

Because there hard to fit into a hot dog if they arnt cut down.

Hypertherm 45 love it. They make what everyone else copies. Long consumables life.

Water separator on compressor, coalescing filter inlet and has it’s own coalescing self draining filter internal. Dry air a must.

Use 911 Motorsports stencils and tub cutting table. View attachment 752801
That's an interesting welding table!

You gotta cut it and fork it, before you eat it.

I'm leaning toward Bestarc BTC500DP. It's got same specs/features as the Lotos, but is way cheaper.

Mike Festiva has review of it:

For an extra $45 if buying through amazon you can get a four year warranty added at check out.

Watched the review, I agree with him on running the unit hard and often out of the gate, especially if you forgo the extra warranty.
I did not buy ant extra warranty with my LOTOS so I ran it hard for the first 3 weeks.

If any of the Caps, power MOSFETs, IGBT's or rectifiers aren't up to snuff the best way to expose them is to work the cutter.
That unit uses the SG55 / AG60 consumables They are very reasonably priced.
Good Luck on whatever you decide.

Sd455dan, that a good idea about the warranty. Question on switching between 220v and 120v, do you guys switch the torch nozzle tip to smaller size?

Don't think they should be used near people with pacemakers, or any kind of arc welding.

My Lotos came without specific wiring but was capable of 120 or 240. I chose 240 and made up a locking plug pigtail that let me plug it into the same outlet my AC/DC welder used. There was no specific instructions for different consumables with different voltages. I thing the transformer just puts out the same current/voltage no matter what the input is. If you use 120 it will use twice the amps as if you use 240. Shouldn't matter to the plasma end of things. 240 is a little more efficient on the input of things as with most appliances.
BTW I looked and my Lotos is an LTP5000D

I have used mine both 240 and 120V. I disagree on the power output though. It definitely has more output on 240v input.
Some of the dual voltage units even have a separate scale around the setting knob on the faceplate for the 2 input voltages

Agree on the consumables, there are no fine cut or lower power torch parts I am aware of for the AG 60/SG 55.

Who's got one or uses one?

I'm thinking of getting this one: https://www.amazon.com/dp/B0052OX87...&colid=TJYU61LC7LU&psc=1&ref_=lv_ov_lig_dp_it

I've been reading comparisons and watching some youtube reviews, that one seems to be a hit.
I bought one of those with a slight variation. Mine is a 3-in-1 machine, tig, stick, and plasma cutter. I love it. The machine works great and is very lightweight for portability when needed, (and that's more often than you might think.) I've had it a couple of years now and have no complaints.

sd455dan, interesting that you saw a difference in output on the higher voltage. I had 240 plug already in place and never tried it on 120. Maybe that is why I was so impressed with it first time out. :)

I know it will slice through 5/8' high carbon cutting edges with no problems if you don't try to go too fast. If I am not using a very good technique sometimes I will get a lot of slag or closeups behind my cut, but that is on me, not the machine.

Sounds like there are a lot of good machines out there at reasonable prices these days. I was reluctant to give up the oxy/acet setup but not as reluctant as paying for gas and bottle rental prices, not to mention I always seemed to run out in the middle of a project on a weekend when the welding store was closed. Plus it was a 30 mile round trip to go fetch new bottles.

A plasma cutter was one of the best investments in my shop next to a big air compressor and a lathe.

Oh I have and will keep my Oxy acetylene, In fact just replaced the hoses and instead of having my Acetylene gauge rebuilt just bought a new Victor. Will need to swap tanks eventually . I am sure it will be a shock when I see the refill price at CO-OP I would keep the Oxy set up just for stuck brake drums and heating bending if nothing else.

I don't know what you are going to be cutting but I have a plasma cutter and use the little Eastwood metal cutting saw the most. The plasma cutter requires a lot of air and the consumables are expensive. It is great for shape cutting however.

Guys, I don't think it's different electrode, it's just the hole size in the nozzle tip was I was referring to.

Like look here: https://www.amazon.com/dp/B08LGRGL44/?coliid=I2F2TMCPEA2LMD&colid=TJYU61LC7LU&psc=1

See, they recommend 0.030" for 110v, 0.045" for 220v.



Then I also found this guy: All about plasma cutting

Relevant part:

This is what I have found to work with most plasma cutter nozzles/tips that most people have in their shops or garages. NOTE: Orifice hole size 1mm = .03937"

20 amp tip - 0.6mm/.025" - 15 to 20 amps - 50 to 55 psi

30 amp tip - 0.8mm/.030" - 21 to 30 amps - 55 to 60 psi

40 amp tip - 0.9mm/.035" - 31 to 40 amps - 65 to 70 psi

50 amp tip - 1.0mm/.040" - 41 to 50 amps - 65 to 75 psi

60 amp tip - 1.1mm/.044" - 51 to 60 amps - 65 to 75 psi

70 amp tip - 1.2mm/.047" - 61 to 70 amps - 75 to 80 psi

80 amp tip - 1.3mm/.051" - 71 to 80 amps - 75 to 80 psi

That's why I don't want to spend a lot, coz I won't be using it all the time, BUT...I find myself hacking off metal things with a recip saw or angle grinder enough to want a better tool to hack them off with.
