Abstract

A portable welding unit comprising a housing. The housing contains a first battery and a second battery connected in series. Each of the batteries is a sealed, non-spillable battery. Each battery has a positive terminal and a negative terminal. The welding unit has a first clamp electrically connected to the positive terminal of the first sealed, non-spillable battery. The first clamp extends outside the housing and is adapted to be connected to a ground of an object to be welded. A welding gun is electrically connected to the negative terminal of the second sealed, non-spillable battery. The welding gun extends outside the housing. A wire feed mechanism is located in the housing and is connected to the battery for extending wire through the welding gun. A spool of consumable electrode wire is rotatably connected to the housing. This wire is supplied to the welding gun via the wire feed mechanism. In operation, the user connects the first clamp to ground. Next, the user enables the unit so that power is supplied from the batteries contained in the housing. Once the unit is powered up and the gun trigger is activated, the wire electrode is supplied through the welding gun by the wir…
