I was wondering where and what Tig Welding Tungsten Electrodes to get. My torch came with parts marked 1.6/ 2.0/ 2.4 I would like to be able to weld AC and DC with out changing electrodes, and just about any metal. and what is 1.6? I assume its "mm" and what would be the sizes in sae measurements?
Most of my welding needs I go to AirGas!
