Welding apparatus
First Claim
1. A rotatable gas metal arc welding system comprising:
- a) a rotatable base capable of unlimited rotation in either direction;
b) a rotation brake coupled to the rotatable base for alternatively (i) allowing rotation of the rotatable base and (ii) halting the rotation of the rotatable base;
c) a column post attached to the rotatable base for unlimited rotation in either direction with the rotatable base;
d) a primary welding boom arm attached to the column post for unlimited rotation in either direction with the base;
e) a first secondary welding boom arm rotatably attached to the primary welding boom arm, the first secondary welding boom arm being rotatable about a swivel joint so as to be rotatable in a generally horizontal plane;
f) a MIG welder station mounted on the column post above the rotatable base for unlimited rotation in either direction with the rotatable base;
g) a first manually operated welding gun connector, the first welding gun connector being suspended from the first secondary welding boom arm;
h) a process controller suspended from the first secondary welding boom arm, for controlling a welding gun and the rotation brake;
i) a rotatable electrical input connection comprising a rotary slip ring coupled to the rotatable base for connecting electrical power from an external electrical power source to the rotatable base;
j) an electrical ground connection coupled to the rotatable base, the ground connection being unhindered by the unlimited rotation in either direction of the rotatable base;
k) a welding wire supply station mounted on the column post above the rotatable base for unlimited rotation in either direction with the rotatable base; and
l) a rotary union located in the rotatable base for connecting (i) pneumatic power to the rotatable base, or (ii) inert gas to the rotatable base or (iii) both pneumatic power and inert gas to the rotatable base.
