Cerbora Pocket25 plasma cutter.

[Alan Reynolds]

Hi chaps. I rescued a Cebora Pocket25 from being dumped.
Obviously it wasn’t working but I’ve gone through it and fixed all the things I found wrong like the air switch, PCB etc.

Now I have air at the torch, one of the contractors pulls in when I press the trigger but the other contractor does not pull in.

Now to my question. I have dismantled the torch tip and the nozzle cover is spring loaded and I can see two contacts in the torch where the cover makes contact with them.

This is a drag torch so will it only work when the cover is depressed?

I assume this will be a safety feature so that you can’t produce a plasma jet and sever a finger or two. Is that correct? Thanks.

I presume you are correct without photo's R-tech use a similar design, so if the outer cone/shield isn't fitted correctly the plasma arc won't work.

you could always try by-passing the connects just be careful when its powered up...


Below is a picture of the R-tech 50amp torch, the 2 blue wires are connected by the brass insert in the shield these are purely a safety cutcut circuit that cuts the plasma torches trigger circuit, if the shield is damaged or loose...

Thanks for that information. I will now give it a proper try.
Nice box of spares there!

You're right. The torch will only work when the nozzle cover is pressed down. It's definitely a safety feature to stop the plasma from firing when it shouldn't.

I've owned my plasma cutter for several years now, but never really been happy with the quality of the cuts in material above 13mm (steel), and never achieved the 18mm clean cut/24mm severance, plus the tips always seemed to burn out quickly.

I needed to stock up on consumables again but couldn't find any sensibly price tips and I'd never found any drag tips for the LT70 torch, supplied with the HF50 machine, so the hunt was on, I ended up ordering a LT80 plasma torch which has a higher amp age capacity and much cheaper cutting tips.

A few weeks later the torch arrived, then a wait for...
