Miyachi Unitek manufactures the world’s most complete range of welding equipment, which includes: power supplies, heads, weld monitors and weld checkers, and accessories – including welding electrodes - for fine spot resistance welding and micro welding. We have more than 50 years’ experience solving customers’ manufacturing challenges, enabling us to offer you the fastest path from fledgling application to full production.

“Fine spot” resistance welding or micro welding generally refers to applications joining either conductive materials, such as silver or copper where the parts are .0003”-.040” thick, or resistive materials, such as tungsten or titanium, where parts are .0008”-.050” thick. Typical fine spot resistance welding and micro welding applications include implantable medical devices, medical components and devices, automotive electronics, sensors, and controls, computer and disk drive components, batteries, and more.

Resistance welding equipment technologies offered include High Frequency (HF) Inverter welding equipment, Linear DC welding equipment, Capacitive Discharge (CD) welding equipment and AC welders, and feature both closed-loop and open-loop operation. With 16 primary models offering up to 4000A output, our fine spot resistance welding line is the most complete line of power resistance welding equipment and supplies for fine spot applications in the world.

Based in Monrovia, California, Miyachi Unitek’s fine spot resistance welding and micro welding operations occupy 20,000 square feet in a facility that includes engineering, a welding equipment manufacturing floor, QA workroom, testing facility, and a state-of-the-art applications laboratory.
