Default dc tig mild steel

i'm having a little trouble with my tig, it welds as though there is no gas, the electrode burns up like it would as if the gas was off. i do have gas flow, pre - during - post welding. doesn't matter which type of electrode i use lanthanated, ceriated, zirconated. i have a gas lens fitted, i recently fitted a gas dryer in the feed line in case of moisture. i'm using and have always used argon/co2 mix, i only weld mild steel. machine is a uni mig 200 a/c

anyone have any ideas? i'm about to change to pure argon just to try it
