1. A welding assistance system comprising:
a) a piping system component holder to securely hold at least one piping system component; b) said piping system component holder comprising one or more surfaces on which at least one piping system component is held and a shaft extending away from at least one of said one or more surfaces; c) a receiver for receiving said shaft of said piping system component holder; d) said piping system component holder rotatable within said receiver; e) said receiver connected to a pivot assembly that allows a user to pivot said piping system component holder between a horizontal orientation and a vertical orientation; f) said pivot assembly comprising a pivot member in a pivotal connection with a base member, g) said pivot member comprising
i) a first plate engaged with said receiver,ii) a second plate connected with said first plate, said second plate forming an upper sidewall of said pivot member,iii) a third plate connected to said first plate and said second plate forming a left sidewall of said pivot member,iv) a fourth plate connected to said first plate and said second plate forming a right sidewall of said pivot member, andv) a pin connected with said second plate of said pivot member; h) said base member comprising
i) a bottom plate,ii) a rear plate connected with said bottom plate,iii) a left plate connected with said bottom plate and said rear plate,iv) a right plate connected with said bottom plate and said rear plate, andv) a pivot connector that engages said pin connected with said second plate of said pivot member that permits pivoting said pivot assembly relative to said base member, andvi) said left plate of said base member and said right plate of said base member are positioned outside of said third plate of said pivot member and said fourth plate of said pivot member; i) said base member comprising an upper plate connected with said rear plate of said base member, said left plate of said base member, and said right plate of said base member; said upper plate positioned above said second plate of said pivot assembly and said upper plate comprising a knobbed setscrew that passes through said upper plate and contacts said second plate of said pivot assembly when said piping system component holder is in a vertical orientation so that when said knobbed setscrew is tightened, said piping system component holder is angled upward to assist leveling said piping system component holder, and when said knobbed setscrew is loosened, said piping system component holder is angled downward to assist leveling said piping system component holder; j) a mechanism that locks said piping system component holder in a horizontal orientation via structure comprising an aperture on said pivot member that engages a locking pin only when said piping system component holder is moved to a horizontal position and said locking pin must be released before moving said piping system component holder from a horizontal orientation, and, when said locking pin is released, said aperture on said pivot member is not occupied, and said piping system component holder moves freely between a horizontal orientation to a vertical orientation, and said piping system component holder is maintained in a vertical orientation by contact of said knobbed setscrew with said second plate of said pivot assembly, and said piping system component holder is configured to move freely from a vertical orientation to a horizontal orientation by tilting the piping system component holder upward without mechanical interference from said knobbed setscrew even when said knobbed setscrew is tightened. |
