im looking for some advice on welds please if you would be good enough, i had a few goes at tig with a parweld 162 now and the equipment is slowly starting to feel a bit more comfortable "just found out that the torch head can be bent to suit my grip which i think has helped " i started by using 1.6 red tungstens on 2mm steel with a normal collet and then tried a gas lense ,i found that the red tungsten seemed to grab at the steel on lift/arc start ,today ive tried some 1.6 blue and found a big difference starting the arc and also the welds seem a bit brighter looking deffinately a big difference using a gas cup !
for prep ive just been grinding with a flap disk to remove scale is this enough,ive read on here about wiping down with solvent is this needed on new steel ?
heres a couple of todays pics "comments and advice appreciated

somewhere on here ive read about using some steel wool pushed into the cup using a normal collet instead of a gas lense,any links to pics would be appreciated just to give me an idea how much to use and how tight it needs to be around the gas holes
