Balling issue

admin

So here it goes..... I took the plunge on a new miller dynasty350  The downside is whatever i set the machine to on AC it is balling the tungsten. I am using 2% ceria (orange band)EN setting: 200EP setting: 100Balance 75%Frequency 100HStarting amperage set at 120 Amps. Machine set to start on EN. Flow Meter set to 25 CFH 100% ArgonMachine amperage set to 125AmpsWaveform soft squarewave3/32 tungsten -- 3/32 4043 filler #6 cupGas lensWeldcraft ws310 torchI am just practicing on 1/8" plate laying beads which are acceptable in appearance but have a bit more etching than i would like, maybe 3/16" all the way around. I am not dunking or using contaminated tungsten. The tungsten appears to look just like pure tungsten when welding aluminum gets a nice little ball on the end in a matter of seconds. Stays nice and shiny. I have searched through the forum about this topic and have found several good posts and answers and have tried several fixes that are suggested and still no luck. I dont think this is an issue but hey they only dumb question is the one you dont ask...Would the machine running on single phase make any difference with this? As you can see i'm reaching for straws here but if i wanted balled tungsten i would have kept my syncrowave 250.I would like to think i have tried every combination possible in the settings but obviously with the result i am having i haven't. Thanks for any help i will post pics of tungsten and beads later when im home. i dont have computer cord for my iphone here.
Reply:* UPDATE* I have fixed the problem What i did is actually sit down and look at the hookups on the machine and saw i made the classic error of hooking the ground and torch up in opposite ports DUHOnce I put them where they were supposed to be i was in business!!!!!What an idiot!!!

Reply:Easy thing to get wrong. Glad you go it fixed. Why are you running EP at 50% of EN?Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
