Claims

[Scope of utility model registration request]

A mounting stay fixed to a welding torch, a clamping member slidably supported by the mounting stay and having a bifurcated tip divided into two pieces, and biasing the clamping member in a direction protruding from the mounting stay. a spatter shielding member whose upper part is slidably fitted between the two pieces at the tip of the clamping member and whose lower end is cut out in a shape similar to the outer shape of the workpiece; and the clamping member. The spatter shielding member is partially protruded from one of the two pieces at the tip thereof, and engages with a locking hole drilled in the upper wall surface of the spatter shielding member to rotatably support the spatter shielding member. A spatter adhesion prevention device for an arc welding apparatus, comprising a ball and a locking spring that biases the ball toward the recessed portion of the spatter shielding member.
