This is where it all started. Thirty years ago, we made history by developing the first Hermetic Sealing Systems. We are still making history today by offering the best projection welders at the most competitive prices in the industry.

For three decades, this 8-station rotary cap welder has proven its reliability, accuracy and speed. The high-yields, dependability and lower initial investment make the 7100 the top choice for demanding production schedules.
