EP500L Discontinued Professional CO₂/MIG/MAG Welding Machines

OTC DAIHEN EP500L Low-Spatter Pulse Welder (Discontinued)

The EP500L was a high-performance low-spatter pulse welder from OTC DAIHEN, featuring CBT-EX DC low-spatter function that drastically reduces spatter across the entire current range – from low to high – producing smooth, beautiful bead appearance. It also came standard with DC pulse mode for high-quality welding. For stainless steel, OTC's dedicated pulse waveform control ensured stable droplet transfer even with sticky stainless steel wires, delivering excellent results. Built‑in welding management offered 100‑job memory, USB backup, waveform analysis, and error history tracking. Rich internal functions (F‑key, 1‑knob presetting, constant penetration, key lock) met diverse user needs. Although discontinued, its technology lives on in the successor model P500L.
