Now here is a list of CO2 laser tubes and laser models we do NOT refill or service.
-- We do NOT refill or repair RF (Radio Frequency) excited CO2 laser tubes such as those manufactured by
Coherent, Synrad or Universal Lasers.
Reason: We only work with DC (Direct Current) excited, glass co2 laser tubes
-- We do NOT refill or repair any made in China laser tube.
Reason: Because if we service it then we have to give it our warranty and we can not do that. Why ? Because they have an inherent short life time due to their processing techniques and we can not extend the life by a refill.
-- We do NOT repair any sealed CO2 laser tube that has FLUID in the gas reservoir (fluid touches the mirrors) because the glass has cracked between coolant and gas reservoir from the inside.
Reason: Interior cracks are Beyond Economic Repair.
Other brands we do NOT repair :
-- all Luxar models and Lumenis Encore (RF excited).
RF excited = The co2 gas is Radio Frequency excited.
DC excited = The co2 gas is Direct Current excited.
Chinese tube = Inexpensive co2 laser tubes that are made to be replaced when they die.
