1. A nozzle for a welding machine used to heat weld materials together;

  • said nozzle comprising;

    a tubular member having a first end and a second end;

    a connector assembly engaged with the first end and being adapted to be engaged with a hose extending outwardly from a housing of the welding machine;

    a welding head provided at the second end of the tubular member, wherein the welding head is substantially L-shaped when viewed from a first direction and the welding head comprises a first leg that is engaged with the second end of the tubular member and a second leg that extends outwardly from the first leg, wherein when the nozzle is in a non-welding position, the welding head is located a distance outwardly beyond a second side of the housing, and when the nozzle is in the welding position, the welding head is located inwardly of the second side of the housing; and

    wherein the nozzle travels through a vertical plane when moving between the non-welding position and the welding position; and

    wherein the nozzle is adjustably engaged with a mounting bracket by a spring-loaded mechanism; and

    the spring-loaded mechanism permits the nozzle to float up and down relative to the mounting bracket during operation of the welding machine;

    a pair of flanges;

    wherein the pair of flanges are spaced apart from each other and are spaced so as to be positioned adjacent first and second mounting plates, wherein each of the flanges is defined a slot through which a respective fastener is selectively engaged; and

    wherein the nozzle is operative to pivot between a first and second position by engaging a pivot rod from locking engagement with the nozzle mounting bracket;

    wherein the pivot rod is operative to rotate about an axis extending along its length whereby the nozzle is now free to be pivoted between the first and the second position wherein the welding head lies outside the housing in the second position.
