Well decided to put my money where my mouth is / was [ got no money left now !! ] and bought one of those Cut40 plasma cutters.
Wow, colour me impressed, surgically removed Gerts Barclaycard from her handbag with no damage to the kitchen sink.
Seriously very impressed, I already have a big plasma, a Cebora 90 amp unit that is big, on 4 wheels, needs a HGV and is permanently connected to Ratcliffe Power Station via a 440v 32 amp plug so it’s not that moveable.
I thought this a portable one would get more use. Uses a normal 13 amp plug and needs dry air at 50 psi.Flies though 3mm plate nearly as good as laser, if it had a controlled feed instead of handraulics I don’t think you would see much difference, 6mm is still clean, couldn’t find any 8mm I didn’t want so tried 10mm and it cut this as well, not as good as laser but better than oxy-acetylene.
Cuts 4mm alloy fine, never thought to try thicker but alloy isn’t as good as steel, even lasers don’t give a good edge, in fact I have some laser cut 4mm alloy here and the plasma is very close.
Consumables are cheap, unlike the Cebora, costing about £11 for a set of 10.
Also unlike the big Cebora this one is far better on EMC, the Cebora will crash the office computer and the big CNC if used at the same time.
This one is fine which now gives me the idea of hanging a bracket off the end of the CNC mill bed holding the torch.
Switch mounted in the spindle, spindle not running !!, and the Z axis can switch it on, X and Y cuts the shape etc.
Small cutting frame to support the work at the side and thrown outside when not in use.
