摘要:
A portable device for welding a heat weldable tube has a main body case, a first electrode supported on an end part of the main body case, a movable member arranged opposite to the end part of the main body case, a second electrode arranged on the movable member substantially opposite to the first electrode, a manipulation member for displacing the movable member forwardly and rearwardly with respect to the end part of the main body case, a first elastic member returning the manipulation member to a predetermined position when the manipulation member has been opened, and a second elastic member providing elasticity in a direction of movement of the movable member when the movable member moves toward the end part of the main body case by the manipulation member.
