The EP500L is DAIHEN (OTC)'s flagship multi-process pulse welding power source designed for high-precision sheet metal and structural fabrication, combining DC low-spatter and pulse waveform controls.
Using pure CO2 shielding gas, the EP500L cuts short-circuit spatter by over 70%, eliminating post-weld grinding. In pulsed MIG mode, single and dual pulse droplet transfer ensures uniform weld beads on carbon steel, stainless steel, and aluminum.
Equipped with dedicated digital communication interfaces for DAIHEN FD series robots and automated fixtures, it is widely utilized across automotive chassis, EV battery trays, and rail transit fabrication.
