Ok i have a Coherent Innova 90 Ion laser

I just want to ask some information according GAS and re-filling
The laser I am sure will not run since its a gas tube laser. The gas ends up being absorbed into the metals in the tube since it did a last run 3 or 4 years ago , this causes a low gas pressure situation and will not allow it to start.

Some pictures

Just so you know. Gas refilling will cost you more than you probably paid for your laser. Not sure but I think a few people have had other Argons (not coherent argons) and it cost them a few 1000$.

You dont seem qualified to handle 3 phase power, but have you actually tried to start the I90?

Considering the autofill system tends to take care of these things?

Its not a write-off until you try to run it.

I work on them all the time and have the manuals, and I repump the tubes.

Well i haven't had the time to open it and check everything , @ home i don't have a 3 fase 25 amp or 32 amp i have 3 fase 16Amp

You actually need 3 phase 45 amp, as shown in picture 2.

It may actually start even after a few years of sitting around. Only one way to find out.

It's probably only using the voltage between two phases (208V), so a single phase 230V may power it up to 16A, that may be enough to reach threshold. That how I hope to get my argons running.

Edit: nope I was wrong here.

In that case with a transformer (which you already have) you can go up to something like 30A, that should definitely work.

The problem with gas lasers is the opposite - when an ion laser sits unused gas is actually released from the walls of the tube, causing the tube to not start from high pressure. You run into low pressure from lots of runtime. As Steve has mentioned there is also the gas fill system and you'd need to try and start it first before you make any assumptions about the state of the tube pressure. The laser may very well start perfectly fine even if it hasn't been used in a while.

You have a furnace in your kitchen? Do you mean the stove/range?
If you do actually have 3 phase (i.e. 3 hot conductors and a ground) then you may be able to get the laser to idle without tripping any breakers. I hope you have experience with at least residential electrical systems before you even think about trying to hook this thing up.

You'll also need a garden hose for cooling.

I doubt he has 400v in his house. Even 208v 3phase is quite rare for residential (at least in the US), but I've had people claim otherwise for other countries so meh

Either our cultures are very different, or something was lost in translation. Here,:

1. Residential furnaces do not require three phase.
2. Furnaces are not kept in the kitchen.

No. It makes no sense to require three phase and then use only one. The three phase is rectified and filtered. Running it on single phase requires drastic modifications as the filtering for three-phase rectification is much less than single phase.

I hope you get it working but do be very careful working on a multi phase circuit, if the a 3 or 4 phase circuit is shorted the flash could kill you, or burn you face off. Good luck and be safe. Got hit by a 3 phase heater circuit in an old Boeing hanger, not fun at all, ah-64 runs a 4 phase circuit that will turn you into a vapor of charged ions.

My Lexel also have a 3 phase 208V plug but can be wired to a single 230V phase. My Spectra Physics supposedly use the same trick but I haven't verified that.

But this Coherent one has a 45A current requirement and can give out 50A of tube current, with a linear power supply that would indeed mean it must use all three phases. I mixed up the numbers so my guess was wrong.

Running this Coherent laser on a single phase is a REALLY bad idea unless it explicitly states somewhere in the manual that you can do it. You risk blowing up a lot of components, including possibly the tube. Don't try this.

Also, 208V 16 amp three phase service, kitchen or otherwise, is not going to cut it (MAYBE it will idle. maybe.) 208 x 16 x 3 = about 10 kW of power. The laser says 16.5 kW right on it. It will be hard on this system for it to undergo an uncontrolled shutdown, and it's already older than I am. I wouldn't risk it.
