应用

Working Principle

The Long Arm Resistance Spot Welding Machine generates heat through electrical resistance between metal workpieces. When welding current passes through the contact area, localized heat is generated and pressure from the electrodes forms a reliable welded joint.

The extended arm structure enables the machine to reach positions that standard spot welding equipment cannot access.

Product Advantages

Extended welding reach for large workpieces

Stable welding current output

Reduced welding deformation

High production efficiency

Strong machine structure

Long service life

Low maintenance requirements
