Using these pure tungsten electrodes is simple. First, make sure you're using a transformer-based constant current power source as they're designed for that. Set your amperage to low or medium as these are best for aluminum and magnesium alloys. When you heat the electrode, it'll form a nice balled end, which helps with a stable arc. But be careful, at higher amps, it might spit a bit. After use, keep the electrodes in a dry place to prevent any damage. And always follow basic safety rules like wearing proper protective gear.
