    Please help A/C trouble

    I am having some issues with a 180 sd. D/C works fine A/C not so well. The arc will spit and sputter about 3 times before it blows a hole through the aluminum, I had both scrs tested they are about 1 ohm apart from each other looking for some suggestions on what might be wrong thanks.

    Matrix... If you ever get to Pittsburgh hit this place

    no kraut coleslaw! And fries and whtever they put on it...

    busy day guys Saturday I will do a better prep, weld and photo... I have a dedicated SS brush, I also hit it with cleaner not looking to open up a can of chemistry and reactions ... I need some burn time but was not getting there due to the bad argon, I have miles to go before I will call it great welding... I am a humble novice but I will follow up and I will follow the welding rules thanks for the replies - I think we pretty much pirated this poor guys thread ... Hope he gets his splatter problem fixed

    Right on Cruizer, I had forgot about HI Freq. Good info
    .....I sometimes like to run 6011 on DC Neg to fill a gap or on thin material, so with Dynasty 200 and Maxstar 140, I swap leads, but other machines I leave alone and switch the knob. Thanks for the fast response,,,,Paul

    OK Matrix, gotta disagree with ya here, Kraut Rules.........looked like you could use a little more clean aluminum, are you wiping down with acetone or xylene or anything after you scotchbright......grease is bad bad bad......and no steel brushes, only stainless brushes........that have only been used on aluminum.......that bead should be shiny and no fly specs.......hope this helps.....oh, the aroma of Kraut.........PRB

I'm going to be able to sleep tonight with the idea that I need zinc blended electrodes and just to take the grounding contamination out of the equation I'm trying to light up with a 1/16 that should just ball up nicely ... No need to put a point on it

    trying to upload a pic because everyone likes to see pictures
    Zinc??????you need to get your readers fixed......someone has probably said something already, but it sure is not Zinc.........Matrix has good info on this....

    Foiled by contaminated argon

    Ok men, first pic should be two light up attempts with new tank... Short one is amps at 70, longer one is 90... Not perfect but good enough with green electrodes and the time I have this morning... Looks like it was the gas not the machine or the man per say just needed to root cause a little deeper!

    Looks like you guys like pics too so... The next one should be my 180sd, the one after that is my welding corner in the shop which my wife thinks is her garage but as cold weather closes in I will have to make room for her car, and the last shot is a yummy primatis samwich from the steel city- I though it was appropriate for the forum and Asa payback to you guys for ready and posting replies!

    Sadly i lost the job but dang it I learned a lot and now I have this forum in my bag of tools and tricks... I'll be ready for the next one!

    looks like the pics are turned around and they don't resize but you guys will get the idea!

    Matrix, no nit picking intent taken on your part it's the auto spell on this silly iPad thing ... But I'll leave that for another forum

    morning brings new information ...Gts manager admits to having some bad argon from about six or seven months ago the one thing I did not do was swap argon tanks. Going to pick up zirc blended electrodes anyway...

    other comments and suggestions are appreciated and all good points and observations... It's Aluminum, it was clean when I started, various cups used, electrodes set up properly and arc length... Well I tried close far you name it... I tried max clean/ penetration balance, low med and high frequency starts all of it great points men! Thanks!! But this may just be bad argon to the shop to try it out
