1. A system for a welding apparatus, said system comprising:
a mobile welding apparatus comprising a left side and a right side;
a first pair of adjustable reference points on said left side;
a first lifting mechanism positioned between said first pair of adjustable reference points;
a second pair of adjustable reference points on said right side;
a second lifting mechanism positioned between said second pair of adjustable reference points;
a welding line positioned between said first pair and said second pair of adjustable reference points;
wherein each adjustable reference point is independently adjustable;
wherein said second lifting mechanism is hydraulic and moves in a vertical direction toward and away from a first workpiece, wherein said second lifting mechanism is capable of applying an upward force on said first workpiece, and wherein said second pair of adjustable reference points applies an opposing downward force on said first workpiece;
wherein said first lifting mechanism is hydraulic and moves in a vertical direction toward and away from a second workpiece, and wherein said first lifting mechanism is capable of applying an upward force on said second workpiece, and wherein said first pair of adjustable reference points applies an opposing downward force on said second workpiece;
and wherein said first pair of adjustable reference points are independently adjustable relative to said second lifting mechanism.
