Tig welder service?

I've long trolled all the tig welder posts trying to gather wisdom. I'm looking to pickup a used dc tig and am mainly looking at the miller maxstar 200's as they seem to come up somewhat steadily around me on the buy and sell.

My question is since I'm going used, and for units that are a few years old now, is there any value in sending it to a service shop for a tune up/health check? Is that wasted money and should I just put it to work and repair if I ever need it?

I've had and really enjoyed a millermatic 135 for 5 years of hobby use and never had any issues at all but I knew that one came from a garage warrior like me. All these maxstar units seem like they're coming out of worksite use.

FWIW the two I'm looking at are the same maxstar 200sd, one has no accessories at all, 35hrs, $1200cad, light industrial use I'm told, clean, appears cared for. The other is asking $700cad, includes ground and stick stinger, no report on hrs, seems like it had a functional on-site life, and shows a fair bit of wear and tear, and dirt. Likely just a simple clean mostly. Big ask price savings and means I can probably have a complete setup for around $1k which is appealing. I'm more of the buy once cry once mindset for this though, and am trying to stay under $1500 all in for all the bits. I've no need for stick.

Obviously both require more bits to tig. The welding work I'm doing is all automotive and fun hobby, the tig want is to do a custom exhaust for my project mk2 vw gti.

Thanks guys for any inputs and wisdom.

Maybe I'm wrong, but there's not a lot of moving parts to wear out on a DC TIG, so if it works, I'd just use it until it doesn't. They might be able to do some testing, though, to confirm that everything works as it's supposed to.

This is probably a fine way to proceed. Nothing I am doing requires perfection from this device. Working or not will be pretty obvious. I'm mostly thinking if $100 gets me some qualified eyes on it, it's a nice way to move forward too. Thanks

The usual service is an occasional blow out with compressed air to remove any dust that might hinder cooling.

If they are dirty. One of the guys on the Miller site was service, said they often git them in plugged and has worked wash them. My air isn't pristine but they don't get dirty here. Took the cover off one a while back, I had it 35 yrs, should have poked a mirror in first and looked, wouldn't have bothered.
Anything can take a dump from age but my Max prolly has bout that on it but 35 is nothing, units that get worked have 2/3000 trouble free hours, some lots more.
Got a bud said they had one in the maint shop and used it so regular they quit shutting it off. Ran like 10 years.
