High Frequency

admin

Hi there,I have a Miller 330 A/BP Ser# L228915. When the machine is turned on and the pedal is engaged the high frequency comes on for about 2 seconds and then goes out.Can anyone offer any suggestions on how to fix this?Any help would be appreciated.Thanks
Reply:Sounds about right. The HF is to establish the arc.Unless you are welding with AC: Find the HF Continuous setting.Be wary of The Numbers: Figures don't lie,. but liars can figure.Welders:2008 Lincoln 140 GMAW&FCAW2012 HF 165 'toy' GTAW&SMAW1970's Cobbled together O/A
Reply:Question is does your arc go out as well.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.
