Rods "Spaceship" Scratch built Plasma Cutter build

hey rod maybe up-size to the GX20 connectors technically oversize but easier to solder. Anything else starts getting pricey.

I was going to look round for crimp on options eg. Amphenol et al. Granted you need a crimping tool but the cost of contract  soldering would pay for it in one job if my current tool does not work. At the motor end recently I've been using automotive QC connectors.

These need a crimper. Despite their looks, they are not compatible with the normal coloured automotive spade connectors.. But they are nice and light if suspended in the air and give a good contact.

I have said it before but I favour SpeakCon (and PowerCON) connectors as they are rugged, high quality and relatively cheap.
I am also keen on Lemo, but bought at a discount from eBay, in general.

Hi Rod, I've been following the spaceship for a while.I'm thinking these would be a far better connector than QC connectors. Used widely in the mining world. Original Equipment for Caterpillar.

Yeh, the Deutsch connectors are becoming quite popular for vehicle wiring. Even the small ones are good for 16 amps. The price of some of the crimping tools is a bit eyewatering.
The QC's are about 1/4 the cost and were really a spur of the moment idea as I was driving past the supplier.

I have also thought of using Amphenol which are another crimpon connector.

There was a thread here that went right through correct wiring and shielding and from that best practice was to run the cable right through to te drive. Cable glands are even cheaper.
 

I second the cable gland Idea not very convenient if you have to disconnect things but if you need IP68 then they are great. Best bang for the buck.
