Abstract

An improved torch providing high visibility of the work zone to the operator, an increased viewing angle, and a reduced obstruction angle. The high visibility torch includes consumables adapted to maintain torch and consumables performance while reducing visual obstruction to the user, by coordinating, balancing, and optimizing design requirements and stack up tolerances. The invention also includes a related low-profile safety switch that promotes workpiece visibility and minimizes view obstruction.
