<P>PROBLEM TO BE SOLVED: To provide a portable gun that improves workability of a worker. <P>SOLUTION: In the portable gun 10 used for spot welding, a power feeding device 60 includes: a transformer 65 for generating a high electrical current; a primary cable 21 connected to the transformer 65; a secondary cable 22 connected to a portable gun body 20; and a connection unit 30 for connecting the primary cable 21 with the secondary cable 22. The connection unit 30 includes: a primary side bracket 31 connected to the primary cable 21; and a secondary side bracket 32 connected to the secondary cable 22. A controller 50 applies surface pressure to surfaces of the primary side bracket 31 and the secondary side bracket 32 when the power feeding device 60 energizes the portable gun body 20, and all the time other than the energization of the portable gun body 20 by the power feeding device 60, the surface pressure applied to surfaces of the primary side bracket 31 and the secondary side bracket 32 is released. <P>COPYRIGHT: (C)2012,JPO&INPIT |
