i was just outside welding, and i go to strike the arc like always, and the tungsten tip just burns......so i thought maybe that tungsten was crap, so i tried another, and same thing happened.....rechecked all my settings (tank open to 18 psi on the regulator, and the welder set to 55)......try it again, and same thing happens, and i just welded 2 nights ago so idk wtf is going on.....so i just got pissed, stopped attemping to weld, and started to grind the tungsten tips back, and i was so ****in pissed that i grabbed a red hot tungsten and burnt the **** outta my finger.....so anyone know wtf is happening??....
