Manufacturer: NISSAN TANAKA
Model: ORBIWELD 12

Features 

Equipped with a water cooling mechanism that efficiently cools down to the rotor gear of the electrode rotation part.

Clamp cassette available in two types: ‘Type A’ for thin (small) and ‘Type B’ for thick (wide) materials.

Optimized internal shield gas route structure in the head module for high-quality welding with minimal burn-through.

Operational buttons on the handle of the welding head eliminate the need for a remote control.

Cables and hoses are covered with a flexible hose sheath to prevent strain on the power connection, which includes a hook for ease of handling.
