You do not need to buy an Elga mate.Damn this is gonna be another punch to this months wage. Ive got gas lenses to buy, collets, cups, bodies, rods (cos ive only got few 1.6 left), stainless rods, my helmet is potato so need to buy a new one, gas refill, better gloves(current ones are clumsy af), trip to the steel yard for some box section and other bits and bobs (always come back with more than i originally planned on getting. Ideas spring to mind when i stare steel in the face haha) and also a Elga optimizer.
Hopefully that should see me for a while
