Product Details



spiral welded steel pipe Thrust current is often neglected in the welding process, because its change is the least obvious in the welding process parameters, but it plays a very important role in the welding process.Because often will drop transition circuit 鍎 number of different electrode diameter, welding rod, welding wire diameter, wire type, weld 鍎 space position and different operators will have different requirements for force.The smaller the thrust current is, the softer the arc is, but the splash is small, which is suitable for small current underhand welding operation.The larger the thrust current is, the harder the arc is, but the larger the splash is, which is suitable for all-position welding and conducive to the continuous stability of the arc.
