Which Plasma Cutter to buy?

[Web Goblin]

Using an H.F. start plasma unit should not be a problem if you get your grounding correctly installed. As you say shielded cables will be a requirement. You will need to get your grounding cables back to a star point and connected to an earthing rod would be a good idea but just make sure your earthrod is installed in a position where the soil does not dry out too much.
Try to avoid any parallel paths for your grounding cables.

I bought the 236 pound model from these people.

Not got it working under CNC yet as it wasn't bought for that but I did test it cutting on a piece of plate tight at the side of the CNC mill when it was air cutting a part to see if it affected it, It was fine which is far better than the old Cebora plasma which crashes everything electronic in the workshop when it runs.

Thanks for the info chaps! It has helped a lot and is just what I was looking for.

I have seen the cut40 plasma demonstrated on youtube and it looks quite good for a Chinese made machine. It's like a lot of far eastern tools thats badged under a large number of brands.

Cheers for now,

Andy.
