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;
further comprising a first rail and a second rail, wherein said first rail is positioned adjacent said first pair of adjustable reference points on the left side, and wherein said second rail is positioned adjacent said second pair of adjustable reference points on the right side, wherein said first pair of adjustable reference points are located on a first side of said first rail, and wherein said first lifting mechanism is located on an opposing side from said first side, and wherein said first lifting mechanism contacts said first rail and applies an upward force against said first rail, and wherein said second lifting mechanism contacts said second rail and applies an upward force against said second rail, and wherein said first pair of adjustable reference points applies an opposing downward force on said first rail, and wherein said second pair of adjustable reference points applies an opposing downward force on said second rail, wherein said opposing downward force opposes said upward force from said first and second lifting mechanism.
