Can I get a useable cutter for £150?

a 40 liter runs it spot on

by the way bigegg it looks like you had started to cut right then it seemed you was gouging it more instead of cutting it
was you going to fast or didnt have enough air to cut it properly

top left looks like it cut right but the rest looks a mess

oh and its 2 extensions or extend your plasma wire on its own thicker cable

I was just practising whilst I had a spare hour.

Upper left is the last bit I cut - think another hour of dialling in will get it right.

i think the settings are 30amps

from skotl as there a good guide even for me to use them and have no problems

I set the air at about 65psi and never touch it after that.

12 mm would be at 50A
8mm at 30A
6mm at 20A
3mm at 15A

Probably where I was going wrong:
I had air at about 30-50, and amps cranked up full.

air was too low 65-70 psi is more than enough

45amps and 70 psi will gouge 10mm

Reading this with interest I'm 50 veev soon and people asking for gift ideas

My compressor is a aldt special 25l job would it be upto the job ? I'm only planning on cutting thin metal like car body repairs

yes it should do as it only needs 3cfm to run the cut 40/50 plasma cutter

i have the 40 litre tank and it runs just fine with that

I also run a 25 litre compressor with my cut 40 the longest run I had is 13 minutes of cutting with the CNC cutter, the compressor just about kept up, the motor/pump was quite warm/hot at the end, as it has to keep up with the air flow, if you do manual cutting there is a better chance it would cope, but at them costs, no brainer if you dont have anything buy it.

One thing to consider is to get a better, bigger air line something like 3/8" or 10mm if you can even the 8mm internal would be better for the plasma then the 6mm supplied in one of the semi ridged plastic coils. Places like K-supplies or other similar places would do them at 10 metres or more for not a lot of money.
