Rocker Arm Spot Welder

W.P.I. pneumatic Rock Arm Spot Welder is an upgraded version of the traditional rocker arm welder. It retains the advantages of the traditional model while incorporating dual-stroke cylinders and two-foot pedal switches for effortless throat opening and spot welding. Its top rocking arm operates in a sizeable arc-shaped curve, and the upper arm holder can be freely adjusted according to the height of the metal box, making it suitable for welding various metal sheets. To enhance the performance of the rocker arm welder, we have upgraded the transformer power and integrated a self-cooling circulating water tank, eliminating external pipelines and water impurity issues for simplified maintenance.
