Airon is the supplier of the most important spot welding gun manufacturers since the beginning of Its adventure. Particular attention has been carried on for the automotive  field with the manufacturing of special spot welding guns for cars and industrial trucks where lightness and force are basic requirements.
Due to the heavy duty in this field robusteness and reliability are necessary to minimize the operation of maintenence.
The following pictures show some examples of cylinders especially developed for spot welding guns ; it is clear how much care has been used to design strong piston rods that have to work under heavy bending moments due to the distance between electrode axis and piston rod axis.
