WH1125 Series Opposed Weld Heads

The WH1125 series weld heads offer precision and repeatability at an affordable price. The WH1125 weld heads offer opposed, or series, weld electrodes and are ideal for general fine spot opposed resistance welding. Once connected, these weld heads can be adjusted for your particular application. The weld head’s electrodes pressure can be adjusted to ensure a strong weld. Head travel height ranges from 0 to 5.25 inches.

The WH1125A weld heads are pneumatic weld heads that require an air compressor. Any size compressor will work since the weld head comes equipped with a pressure regulator. Once connected, the air pressure and head travel speed can be set to any preference. Welds are quickly and easily made with each compression of the included foot pedal switch.

The WH1125M weld heads are manually operated. These weld heads require manually lowering the weld head’s electrodes by means of an extension lever and pedal. Pressing on the pedal results in smooth vertical head travel for precision and control when welding.
