Hi guys!

I bought a Everlast 185 AC/DC tig welder few days ago. I never welded with tig, i only have a little idea. I read and saw videos about tig welding and differences of adjust in the machine. I have a 47OHM foot pedal. The pedal is the correct for this machine? So, i need buy electrodes and rods. I want weld aluminum and stainless steel, my priority is aluminum. What electrodes i need for aluminum and stainless and what rods. I saw differents sizes, ex. "aluminum rods of 1/16" x 36", 1/8" x 36", etc. I saw differents electrodes by colors, differents sizes and differents descriptions, ex. "2% Lanthanated Tungsten TIG Electrodes 1/8 x 7 Blue", etc. If any can help me about is appreciated!

Thanks!
