I bought this argon off ebay a while ago in as-is condition knowing I could very well have a dead laser on my hands, but after wiring it everything seems functional except that once the discharge ignites it only lases for about 2-3 seconds before it goes out and tries to re-light the discharge. Not sure weather or not it's a problem with the light board inside the head or the power supply itself. The head is an Omnichrome 532-prep-a01 and the supply is a 170B.
