Re: [TCML] Tungsten electrode thickness

Jay, 



Well, if you plan on staying within the "nameplate" 3 kVA 

rating of your PT, you'll probably be ok. However, I know 

that a true grit coiler is hardly going to be able to resist the 

urge to push the real power throughput potential of a PT 

and herein may be a problem. ;^) We all know that 

PTs and pigs are robust beasts and can easily handle 

2 to 3x their nameplate ratings for the relatively low duty 

cycles of even "long" coiling runs. (At least that's been 

"my" experience). Just "how" extended do you intend 

your runs to be and do you plan to keep the power 

throughput of your runs at or less than 3 kVA? 



I personally use 3/8" diameter x 2" long pure tungsten 

rods for the flying electrodes and 1/2" x 3" long pure 

tungsten rods for the stationary electrodes of my ARSG 

for my Green Monster Tesla coil system. Of course, I 

also routinely run >15 kVA through my 10 kVA pig 

powered coil, too. I know several list members have 

used 1/8" tungsten rods for "propeller" style rotary 

gaps and have run power levels in your proposed 

range with success (Terry Blake?).  YMMV

Hello everyone, 
I was curious to know if anyone has produced a table relating tungsten electrode diameter to Power supply KVA ratings. 

A list member generously hooked me up with some 1/8" rods and I am wondering if they will be fine working with my 3Kva potential transformer for extended run durations. 

Thanks, 
John "Jay" Howson IV
