Using these Lincoln 2% Lanthanated Tungsten Electrodes is straightforward. First, make sure your equipment's amperage is within the 330 - 480 A range if you're using the 5/32' diameter electrode. Then, install the electrode in your welding machine according to the machine's instructions. These electrodes work with both DC and AC currents, so choose the right one for your application. When it comes to maintenance, since they reduce oxide build - up, you don't have to grind the tip as often. But if you do notice some oxide, use a proper grinding tool. Always store them in a dry place to keep them in good condition. Also, make sure to wear appropriate safety gear when using these electrodes.
