Welding copper using micro-TIG welding
Copper dissipates heat faster than almost any other structural metal and oxidizes easily. This traditionally makes it difficult to weld. How pulsed micro-TIG welding with the Lampert Micro Arc Welder delivers the concentrated heat input that is essential for Cu-OF, Cu-ETP, and CuCrZr—and where the limitations lie.
