Re: WTB: Power supply for 2214-40MLA argon

As far as I know you can't buy an off the shelf controller. It is not what the original intent of the manufacturer was, so it needs to be incorporated into the power supply/ driver. There are many sources for how to add one to the supply you are buying. I haven't personally ever needed to do this, so it is out of my area of expertise. If you find yourself with no other options, let me know and I will get with the people i know who have done this before. But, I feel certain that someone around here has the specific information you need to do this.

Re: GUIDE: Which company should I buy from?

Well, it seems that this controller has the same 25-pin connector, shouldn't it work?

Also, what type of fan should I purchase?

You can get off the shelf controllers but it's usually way cheaper just to build one.

Yes - that's the right controller. You can DIY what you need for much less though. Schematics are on the Laser FAQ - I can dig them up for you tomorrow. I'll see if I can find the fan specs then too. Will see if I have a copy of the manual handy ... was on a machine that suffered a drive failure the other day. Fan specs are in there. :)

I stand corrected on the controller. I didn't know that there was enough of a demand for them to have ones ready to buy. Learn something new everyday. :)

Understandable - you don't see them all that often :p.

I imagine it was an optional add-on when purchasing an entire system. Keep in mind many of these argon lasers were intended to be OEM components in a larger machine - so no need for that front mount controller. Likely the manufacturer of the complete machine would design their own controller to interface with the PSU and their machine.

Good option if you don't mind dropping the cash on it - I'll stick with my basic switch/pot/multimeter setup though. :D

FYI Sta - you can run a regular straight through 25 pin parallel cable (Same as the cables used for ILDA on projectors and old printers - just need DB-25 male on one end and female on the other) between the controller and PSU if you want it to be a little more "remote". That's what I always did.

Fan specs as per the manual:



Full manual located here: http://laserpointerforums.com/attachments/f46/42153d1371274975-permanent-thread-ebay-other-internet-finds-interest-read-all-op-please-sub-jdsu-2010-operation-manual.pdf

So you want a nice ~185CFM squirrel cage fan. The fan needs to pull air through the head from front to back and push it out the back. You'll likely need some ducting to get that going. Diameter of the duct adapter on the back of the head is 3.8" according to the drawing - may want to measure it yourself to be sure.

Something like this fan should work OK: 4" Inline 190CFM Hydroponics Duct Tube Exhaust Fan Blower 120V w Leather Sleeve | eBay

A little lower on the CFM rating won't hurt, I've seen several 4" blowers like that with a rating of ~175CFM. Wouldn't go lower than that really though. The tube does have a temperature interlock - but you want to avoid tripping that if you can. ;)

Having a hard time digging up the appropriate squirrel cage blower... Someone here or on PL will have one. This is why I prefer the 2211 and other box shaped heads... Just a beefy 120mm axial fan for those. :D

Hopefully your tube is in good condition - I've seen the 40MLAs do >100mW at ~10A tube current (10A is above rated, so short runs only at that current). Should get at least 6 lines too (again, assuming good tube condition) - like this:



Above picture may actually be 7 lines... A couple pairs of lines are real close to each other and sometimes blend in.



OK ... I'll try and stop updating this post now.

Re: WTB: Power supply for 2214-40MLA argon

These are the only two I see atm as far as ebay goes. There used to be a bunch, but guess most of them sold at some point or didnt come up in my search. BMI surplus might have some too, or Chad and Dennis at Meredith Instruments, who also sell the nice digital controllers, they might have some. I'll keep looking for ya. most of em are big. I've got one of the more modern little ones luckily.

Hi, ultimatekaiser. I was hoping you might chime in here as I know you have many argon lasers and have more knowledge about them than I. Thanks. :)

Thanks Kaiser! Do you know if either of the power supplies I posted earlier will work?

Re: WTB: Power supply for 2214-40MLA argon

Folks, how about this power supply? It appears to be intended for the 40MLA, so I would be more inclined to trust it.
Thoughts?

Last part of the model number won't matter. Just the 2214 part. The other power supplies you linked were the correct model too - whether or not they work is a different story...

However, the interlock for the other power supplies appears to be covered by something... is that of concern? This one includes keys, why would the other ones have the indicator but not key switch?

Just means that interlock has been bypassed. Just covered up the hole where the keyswitch normally is seeing as it isn't needed (perhaps it was hidden inside a larger machine). Probably implemented it elsewhere - both the controller and head have interlock "loops" in them too. Won't fire up without those being closed. You could put a key switch on the controller.

Okay, that's fine. In that case, out of the three, which one do you recommend I go with?

Re: WTB: Power supply for 2214-40MLA argon

yes it probably is missing the key switch due to it being implemented as an OEM supply in another device and was driven from another location by remote. It's not of much concern. the remote also has several interlocks so its not anything to worry about much. If you really want the key switch you'll have to get another supply. I don't recommend digging in these, as its highly dangerous...though it is possible you could add one if you knew where it was supposed to be connected, presuming there were no other necessary changes to the supply. realistically it still wont turn on without a controller attached likely, or some method of input. most all the ones I see have the key switch and they just turn it on inside the machine anyway and use the remote to implement the interlock. but not always. usually the makers of the supplies of any laser usually provide multiple ways to implement them, including all features so they meet CDRH regulations both in and out of a machine. just depends on what the original purchaser wanted.

Thank you kaiser, that is very helpful. Out of the three PSUs I posted, which one would you recommend? (I think 2 of them are on page 2.)

Re: WTB: Power supply for 2214-40MLA argon

honestly, all of the mentioned ones (i remember seeing) should work. its not an exact science for these really. most of the supplies are interchangeable to a pretty high degree. I'd recommend one of the two I listed for safety sake as they're complete with all switches minus the remote, but the gold box OEM ones would likely work fine too. Just a matter of what you want.
