Hi all.
I have lurked here for months and have read a lot with interest, but now find myself with a problem and hope someone can help.
If you own one of the Chinese made, German manufacturers' Berlan Plasma cutters, may I ask a favour? Berlan BPS-40
Could you take the top of the plug off and id the wire for live, and the wire for neutral?
This should be easy, but it is not. I had a friend take a look 9 40 years + in the service engineer game and he is stumped. I will tell you why;
Basically, there are 3 wires as you'd expect; we have id'd the earth by showing almost no resistance to ground - this wire is blue and yellow 50% striped.
This leaves us with a solid Brown, and a pink with black stripes.
We almost wired this brown as live, but took the case off just to check. The pink & black wire hits the PCB board and a red wire comes from that...this is where the doubts come in as red is usually live. We looked at the boards trying to id a capacitor or diode or some other easily polarised component and we are more stumped than ever!
We traced the path of both pink striped and the brown and they both hit the board on solder rails that seem +ve. Which can't be the case, unless we are missing something.
I said I'd email the manufacturer, but they don't reply. This problem came about as I put a regular UK plug on the machine, replacing a blue euro one. Back when I took the old plug off, it was easy to note which pin did what.. I could see which was L and N when I took the old plug off, but didn't make a note and can't remember now I just have 3 wires looking back at me ( I am 40 years old after all ) lol
So, can anyone help me out please? I need to put the plug on as a friend wants to buy it and I hardly ever use it.. so would prefer the beer tokens and don't want to see 150 of them go up in a puff iof smoke lol.
Thanks for reading, thought I'd let you have a laugh at these bl00dy machines and their bl00dy silly wires lol.
