1.In most cases, we use chromium-zirconium-copper electrodes, and when chromium-free zirconium-copper materials are available, we tell customers to use red copper instead.
2.welded galvanized sheet/Due to the coating, the iron sheet is always prone to adhesion during high-temperature welding.,A small amount of zinc even adheres to the electrode tip,Over time, it is easy to have poor conductivity and make welding difficult.
firm,It is recommended to use aluminum oxide copper electrode,it has a diffusing effect,Good anti-adhesion performance,Although the price is slightly higher,But good operability and high efficiency.
3.Welding copper,Gold and silver jewelry use tungsten electrodes, Tungsten electrode has stronger wear resistance and is not easy to be lost. IfIf the requirements are high, add a small amount of solder to make the welding stronger and more beautiful.
