Solder supply device including a nozzle with a piston and a demarcating member that demarcates an air chamber in which air is supplied to move the piston relative to a solder container

A solder supply device comprising:

• a solder container housing liquid solder that is tubular, is open at an opening provided at a first end of the solder container, and includes a bottom at a second end of the solder container;
• an outer tube inside which the solder container is stored;
• a nozzle, for ejecting solder from the solder container, that is inserted into the solder container;
• a piston that is provided on an outer circumferential section of the nozzle and that is engaged inside of the solder container from the opening of the solder container;
• and
• a demarcating member that demarcates an air chamber with at least one of the following:
• a surface of the second end of the solder container, an adapter attached to the surface of the second end of the solder container, or a surface of the piston facing the opening of the solder container,
• wherein the solder supply device supplies solder from a tip of the nozzle by relatively moving the solder container and the piston by supplying air to the air chamber such that the piston advances inside the solder container between a first position and a second position, the piston being closer to the opening of the solder container in the first position than in the second position, and
• wherein, in the second position of the piston, the solder container and the piston are removable from the outer tube as a single assembly from the outer tube.
