Has anyone been having issues with China sourced tungstens for their TIG? I bought some stuff off Amazon supposed to be 2% Lanthenated but it's fracturing and splitting on AC......my Thoriated stuff (DC) is old Linde stock works like a champ! I'm using a dedicated diamond wheel to sharpen the stuff. Gas system is fine, water cooler is fine. Please tell me brands your using with good quality.
