Abstract:
1. A welding torch with a variable power trigger, which comprises: a holdable torch gun having a first connection for hook up to a gas or water supply, and a second connection for hook up to a power supply, said gun having a discharge barrel with an outlet end, and a handle extending downwardly from said discharge barrel, said discharge barrel having a front facing in a same direction as said outlet end of said discharge barrel, and said handle having a variable power trigger located thereon such that said trigger is hingedly connected to said handle with a pivot member and said trigger is spring loaded to be biased away from said handle and may be moved by pressure toward said handle, said trigger having an unsqueezed position and a fully squeezed position and a range of motion area between said unsqueezed position and said fully squeezed position, and said handle having an amperage control mechanism located therein and connected to said second connection; wherein said trigger is moveably connected to said amperage control mechanism such that said unsqueezed position prevents any current to flow to said discharge barrel, said fully squeezed position permits maximum current to flow to said discharge barrel and any squeezed portion therebetween permits a proportionate amount of current to flow to said discharge barrel in proportion to distance between said unsqueezed position and said fully squeezed position.
