Killer Tools and Equipment has been building collision equipment in California for 15 years. The Aluminum Discharge Welder has a unique design, built with the collision shop atmosphere in mind. Many users want to move their welders to the vehicles that need work, rather than move the vehicle to the welder. With that in mind, it was built with large, 8-inch rubber wheels and a push handle for mobility. Very powerful discharge capacitors allow it to work on both aluminum and steel.
