Key Parameters and Recommendations

The welding guns are designed for integrated transformer applications with specific power ratings and force capabilities. Cooling water consumption and air pressure limits are critical for optimal operation. Multiple throat depths and arm configurations allow customization based on welding requirements. Both pneumatic and electric drives are available to suit different operational preferences.
