1.2m x 0.6m plasma, <£2k questions!:

9.6 cubic feet per minute is 270 litres per minute @70 psi!

And the cutter that Clive linked requires around 100 lpm at 4.5 bar, so we should be okay.

Would you recommend the CROS-ARC 40?

I'm looking at ordering one this weekend.

Do you think a machine torch is essential or a luxury? Packaging is obviously much nicer! But functionally?

Ta! C.

On a machine the functionality of the machine torch is why it was made so.
With a hand torch the protruding side will always get stuck on something, to much weight on one side of the Z axis might tilt it so the cuts end up worse, no way of aligning it properly without a fixture.

I am happy with the cutter and glad I got the 80A machine torch. I will dig out the model tomorrow. A Hypertherm 45xp would have been nice but it is 3 times the price.

Funnily enough I am helping somebody set another machine up with one of those and is on route to me.

Thanks Tommy!

Where do people in the UK source rails and carriages? Any recommendations?

The plasma itself is still only 40A though? So the machine torch @ 80A only runs at 40A with this unit?

I've just sent WeldersWarehouse a couple of questions on it too!

This guy is very well known on the mycncuk forum I have dealt with him for several years, he sells various qualities and answers questions very quickly.

Just dropped him a line for some linear square rails. Thanks Clive.

What have people used for the floating head slide? Nothing too complex. But stiff?

The very simple and very complicated versions.
