TIG SLIDE RULE
TIG welding can be confusing. What amperage and polarity to select, what size and type tungsten do I use, what gas flow rate, size filler rod, shielding cup size, and gas mixture do I use? What changes should I make when I weld on aluminum, stainless, nickel, magnesium, copper, or titanium? All of these answers and more are quick and easy with the TIG Slide Rule. Size is 7" x 9-1/4"
