HISEN Enterprises, established in 1967, is a pioneer in transistor generators for pipe welding, as well as heat treatment and high-frequency machines in Taiwan. Our products include High-Frequency Tube Welders and High-Frequency Induction Heating Equipment.

We have constantly improved our technology with SiC Mosfets, resulting in lower impedance, smaller size, and higher efficiency. These improvements have also led to a 5-10% increase in output, efficiency, and speed, with a 5% reduction in electric power consumption. The physical size of the welder is down to 61% and the required ground area is down to 72% of a Si welder.

With 56 years of experience in the pipe welding and heating industries, we are ISO-9000 and ISO-14000 certified. We provide high-quality products, competitive prices, and excellent after-sales service to meet the specific demands of our customers.
