Not being a welder in the family, I asked my husband to "burn a stick" and explain the details of how these tungsten electrodes are preformed. He said the following about 1/16 electrodes. I have found these tungsten rods to be excellent for beading thin material like 1/8" steel. I ran the machine (inverter based) with a 33 Hz, 33/33 DC pulse at 130 A to test a 1/8 inch diameter silicon bronze rod on a 1 inch diameter steel angle. It took me a while to dial in during runs (as I'm learning how to control silicon rods without buckling the base metal) and once I got the hang of it (along with rod dipping, which required me to stop and the tip) - the bullets ran smoothly with good convergence. I've run it up to 180 amps and they've held up very well and given off enough heat to bend the angle steel and attach really good beads. I then switched to standard DC @ 130 amps, which worked very well. This has allowed me to reduce the current required to work the needle for very fine work, which is very handy when working with 3/32" stock. Overall, I recommend these 1/16" tungsten electrodes as a good tool for inverter machines.
