Micro TIG Welder

Overview and Applications

Sunstone Engineering has designed the most powerful and robust Micro TIG / Pulse Arc Welders on the market. Our biggest to our smallest micro tig welders are ideal for industrial applications like mold and die repair, medical devices, and unique welding solutions. Sunstone Technology is infused into all of our welders to deliver power, repeatability, adjustability, and affordability.

Sunstone & Orion Micro Tig Welders are perfect for laboratories, universities as well as research and development facilities. Designed for maximum versatility and control, they can be adjusted for extremely fine welds to very large welds. Weld spot diameter size ranges from 0.1mm to 4.0mm. A variety of metal alloys and different thicknesses can be welded at the touch of a button.

Pulse-Arc / Micro TIG Welders

Pulse Arc welding uses electrical energy to create a plasma discharge.  The high-temperature plasma, in turn, melts metal in a small spot.  This process takes place in milliseconds.  The process is clean and very controllable – perfect for intricate and minute welding applications on precious and non-precious metals!. Filler metal can also be added to build up joints and create strong and reliable weld “beads”, or weld seams.
