Performance
This product adapts advanced copper electroplating
technology. The surface of welding wire is smooth and
level and the copper layer is uniform and firm. Being
adapted cisarrangement technique. it has excellent weld
technology property and many advantages such as stable
arc. small splashing, smooth and beautiful weld line,
convenient to send welding wire and high work efficiency,etc.
It is suitable for auto and semi-auto omniberaing weld.
