So sorry to hear of your frustrating situation:
The manual for our Denton, high vacuum, coater states that it uses a 1 KVA capacity stepdown transformer to supply 0-24 volts to the carbon rod electrodes. The meter reads 0-60 amps A.C. but the manual warns to never exceed 45 amps
for more than a minute.
Hoping for a safe and effective solution for you,
Gary

Subject: [PROBEUSERS] Emitech K950 Carbon coater issue
Hi all.
We’ve been operating with an Emitech K950 carbon coater which has recently failed. It appears to be the power to the carbon rods that has gone. While a replacement is on order, after a wait of three months it still hasn’t been delivered,
and we are reaching a stage of desparation. If it is just the power to the rods, I’m considering if we might be able to rig up a temporary solution with an external power supply. Does anybody know what voltage and current this type of coater the carbon rods
require to properly outgas and ablate?
Best wishes, Jens
