Get yourself a gas lens. Our Lincoln Precision TIG 275 came equipped with one, but most TIG machines will not. The one on the right is a traditional collet body; on the left is a gas lens. The gas lens uses a tiny screen to create a more laminar flow of shielding to the working area to create a cleaner (and stronger) weld. The main benefit for the newbie is that they help keep the welding surface more flushed clean and inert, letting you focusing on your technique.
