The function is to hold the welding rod and conduct the welding
current during welding. It is used in conjunction with the arc
welding machine. During manual arc welding, it is used to hold
and manipulate the welding rod and ensure the electrical
connection with the welding rod. Welding tongs have main
technical indicators such as shell protection, electric shock
protection, temperature rise, welding spatter resistance, and
drop resistance. Use cast copper as a clamp, and ceramic and
plastic handles as insulators. It should have good electrical
conductivity, not easy to generate heat, light weight, firm
holding of the welding rod and convenient for replacing the
welding rod.
