Looking for recommendations for a plasma cutter up to around the £500 mark (but don't mind if it's cheaper!).

Initially needs to cut around 5-6mm steel but versatility and the ability to cut thicker stuff with a decent duty cycle would be good. Air supply not an issue.

The R-Tech P30 seems to be well thought of but not currently available until next month for some reason.

Bumping for the daytime crowd, may be better during the week I guess!

I would post this in the Technical section - you will get a much better response there.

Thanks - I'll ask a mod to move rather than post twice.

All I can do is recommend the RTech, but that's of no use.

I bought a P50 about six months ago.

No complaints, replaced a temperamental Miller one I've had for about 20 years.

Thanks - I just checked and price notwithstanding, that's also on back order!

I'd guess it's supply issues from China, possibly an increase in demand from hobbyists.

Hope you have a good compressor as they are air hungry devices, the cheapest rtech one needs 100 litres per minute at 50psi.

My 25A plasma cutter overheated the power/pressure control switch on a 3HP 150 litre compressor.

You must be doing a lot of constant cutting though to do that, normally the compressor gets chance to catch up in between cuts.

Air is not a problem, it would use a chunky 3-phase compressor, not sure of the output but I’m sure it would be “adequate”!

I have the r-tech p30c. It’s fine. I might be doing it wrong, but so far I'd say my plasma cutter makes my angle grinder look like a precision tool.
That said, I'm inevitably doing it wrong - the tool is good.

R-Tech also are excellent - I have found their customer service really really good.

I have an R-Tech P30. It's fantastic.

I will echo the comment above that unless you put a lot of time and practice in, it isn't the cleanest way to cut. I've seen the likes of Urchfab on YouTube do razor-sharp cuts with one, though, so it's definitely my ability rather than the tool at fault (story of my life laugh ). Still, a quick once over with the Dremel and it's all good.

You'd need quite a few discs to cut a 300 square out of 6mm steel plate.
Plasma will cut holes and irregular shapes, curves etc.
It's far, far quicker.
