    Default maxstar 85s

    I currently own one of these machines. I purchased it approximately 10 months ago. I have used it for a couple of big projects and countless small ones, it has worked flawlessly. It will burn tiny rod at about 10 amps. It burns 3/32 hot. No need to be wide open. You will need a 20 amp 120volt breaker, make sure you have this option before buying. (sometimes if you have an older breaker box, these 20amp breakers are unavaliable). It will not run a tig torch, as I have tried, (H80N suggested). The arc starts then quits, there is a process switch on the 140 and also 150. At the shop where I work we have a 140, i took it apart to figure out why it failed. The answer? A small sensor for the fan failed, yup burndown. A $2 part and the entire unit is a doorstop. Mine is bypassed to run the fan all the time. I would recomend this if you happen to find a used unit either the 85s or 140.(Fronius built units). If you have any questions on this don't hesitate. cheers.

    sorry to bring this old old post back up again..but I was curious if anyone has played with a maxstar 91? reason I ask is that someone at ebay is selling it and im interested in purchasing it. I will be using it as a TIG machine (Eventhought I have never tigged before). Someone pointed out to me that the duty cycle is only 20% which only gives me 2 mintues of welding time and I need to rest. My question is that with 20% duty cycle, is that sufficent enough? I understand that I cant weld thick stuff with this, but does anybody know how thick can I weld?

    Thank you in advance...

    best regards,

    cleaver,

    An 85-90 amp machine will weld roughly 3/32" material. If you want to bevel and multipass, then 1/8" is achievable. Either way you are at the top end and have the short duty cycle. Why don't you take a look at the Maxstar 150 or even 200 if you need DC only? The Dynasty 200 series offers AC and DC. The AC is typically used for aluminum and magnesium.

    The 91 was intended for much thinner material and was not designed ot weld the thicker stuff. Most of the ones I have seen are 1 phase 120 volt machines. I have also this or a very similar machine in a 3 phase 460 volt power input. Check before you buy.

    Hi Hawk!

    Price is a BIG factor! hahaha...dont have much money to spend on a welding machine. I was thinking of something small first to learn TIG and if I really want it..then maybe I can upgrade. I will be buying a MIG aswell so my plan was to use TIG for thin stuff (like 16ga tubing and such and for thicker materials I use a MIG (looking into getting the HH180/175/MM175). I do dream of getting the Dynasty...but I dont have the $$ sorry!

    I was looking at the Maxstar 140 aswell, I heard good things about those from MAC. He had it before and he said it peformed well. How much are the TIG torches, like for example if I were to buy either the Maxstar91 or 140, they dont come with a tig torch and whatever is needed...it only comes with the electrode holder and the ground clamp. What do I need and how much will it cost for me to setup to a TIG? Sorry about this, I dont know much about tig.

    regards Hawk

    Default torches $$$

    if you are bying a used power sorce like the maxstar 91 you will spend more on your tig setup than you did on the box.you are looking at spending around $600.00 to get set up for tig.you might look into a package deal on a maxstar 150 with contractor kit (tig setup)on the net some realy nice prices out there on the hole package.around $1000.00 new in the box with warenty.i have used this company for my mig and my plasma cutter had it at my dore in 3 days.

    i have also herd good things abou this comp.

    if you need to save $$$ you will most likely need to buy on line you will still be able to get youre local dealer to do warenty work 4 you. my local dealer is going to teach me to tig after store houres if i get my machine from him and that is well werth spending a little more to get better local service .it is all about what you afford .if you can buy local if not you will still need youre local store for consumables and im shoure youre local dealer will be happy to help you even if you buy off the net eather way you will soon be needing him.
    good luck i hope this helped!
    happy welding

    Default 150 STL

    Cleaver, I would be hesitant about buying ANY used peice of eletronic equipment on ebay. You have to realize that any welding unit not built in North America will not be servicable here. The reason is that you have to buy the ENTIRE board if repairs are nessesary. We have a 140 at work and its dead because of a sensor failure. I'm somewhat of a "do anything" kind of person, and I tell you that when trying to find the main ic on this particular board, it's hopeless. Board cost: 800cnd. Manufactured: Austria. English: the darn thing ain't worth fixing! PS: I sold my 85s to a co-worker for $250cnd and ordered the 150stl. Buy the 150stl new, you get three years warranty, good deal!!(made in usa) We are a dealer and I'm familiar with the pricing. Shop around, at $1000US you should be able to get this welder cheaper in Canada. (factor in:exchange, any duty, gst, pst). cheers.

    hi fun4now and 1fasbu,

    So basically dont buy huh? Ok then..hahaha, I dont know much about the machines thats why so I will listen to the pros!

    I was looking at the Maxstar150, but if I spend that much already, why dont I get a Squarewave 180SD? so I can also do aluminum? Because here locally (at KMS tools), they retail the 180SD for around $2000cnd, and the Maxstar for around $1500cnd. It sucks that price is my main concern here, and of course I wanna learn how to TIG. Someone told me to get a small inverter machine (like 80amps max) and just buy a tig torch with the gas line and the gas tank and regulators and start tigging. I can set one up like that for around $200usd, which is in my range. I know im limited on what I can do because of the max amprage on these cheaper alternative, but how I see it is that if I can start learning how to TIG..why now right? then ill upgrade later!

    oh...1fasbu, what part is needed for the Maxstar 140? If you dont mind telling me can you give me the IC part number? what kind of an IC is it? I work for an electronic repair shop, and maybe I can locate it for you...

    well, thats all I can say..I am actually inbetween deciding which one to get a MIG or a TIG??!?!

    For a mig, I am looking to spend on a HH180 (I have purchased a cheap one before already and sold it) so now im ready to spend a little more...so if I can find around the same range of a TIG machine, ill consider it or am I hopeless?!?

    Thanks again everybody for all the help, much appriciated!

    regards,
    cleaver
