I just received a 325ext and am pretty disappointed in the HF start. Lanthanated and ceriated tungsten sharpened to a point, pre-flow and post flow settings all over the place, foot pedal and 2T, more gas, less gas, it's just flat out inconsistent. My last welder, a hobart 165 with HF start, never had the issue. Reading some of these posts has me thinking I'm just stuck with it.
