    Default Miller Maxstar 150 tig/stick

    Hey guys what do you think of running root passes with a Maxstar 150 in stick mode ? Im running roots with 6011 on this machine and all it wants to do is try to snuff out. I have to fight to keep the rod lit and keep it from sticking even with higher amperages.

    This is the machine our shop purchased to weld a high pressure steam line contract we have.

    I think its a joke and they should have purchased a CST 280

    Well....I have a 150STL, and have done 6010 roots, its not the easiest thing to do..but its doable. Ive had to use 3/32 5P keep a very tight arc, and really couldnt whip it like you can on a bigger machine. I dont think the machine has enough potential to sustain the arc through a big whip. Cant speak for the CST280, as Ive never ran one, but about 6 months ago got a Maxstar 200...and it runs amazing. Plus its super portable. Ive ran it on everything that it can handle from 120-480v three phase and it hasnt let me down!

    If there is a welding machine out there that is not given the credit it truly deserves, it is the Miller CST 280. Truly a beautiful welder with more than enough power. I thought my Dynasty 200DX was a great stick welder and it is but oh boy the CST is smooth on all rods I have put through it.

    What diameter rod are you using? I can run 1/8" and get 50% penetration on 1/2" with my 150 without having to max out the amps.

    Mine is good with 1/8 6011, if your procedure allows this the machine should do it. I can do big whips with 11. Maybe something is wrong with the unit,,, call Miller on this one, we on the right polarity?

    I ranked it good in the start dept compared to a tranny like a Dialarc. Not great but side by side with a couple other machines I will say it requires a bit more fussy discipline to get great starts. I thought the other 99% I wouldnt know which machine I was running.

    Built a handrail out of used galv well pipe the other day, it was outside in the breeze, I cleaned the plsma cuts some, had some gaps, I scuff some galv off, nothing reallly well or clean, welded right up and around.

    If your running 6011 try switching polarity to straight and it will run beautiful. In fact i usually run straight polarity with 6011 no matter what machine. May not be "proper" but im not always proper.... jus looking for good results.

    I have a Maxstar 150 STL Great welder for going into confined space with. It has a place I would not want to do a bunch of 6011 root pass with it. Mine runs 6011 great but it's still like comparing a bluestar to a trailblazer it's not apples to apples. It's not perfect scenario but ill tell you at work a lot we make work with what we have. I don't know how much pipe your welding so I can't comment if your company was out of line.

    We use the 150 mostly for tig. Light work ok. Ok, for stick small pipe.
    Real stick welding we go to the CST 280. BIG DIFFERENCE .

    I can have the bloody thing on 90 with a 1/8 6011 running a root, keeping a tight arc gap and she will snuff out and stick. I think it is a ground issue, im even having trouble starting 7018s.... The ground clamp on the machine is a joke. Think I will change the ground clamp tomorrow...
