-
Advanced IGBT Inverter Technology: Engineered with solid-state IGBT modules and high-frequency switching to deliver maximum power efficiency, low heat loss, and compact portability.
-
Hot Start & Arc Force Regulation: Built-in intelligent circuitry prevents electrode sticking during striking and automatically stabilizes arc current under varying load conditions.
-
Wide Amperage Range (200A to 450A): Available across 200A, 300A, and 400/450A variants with duty cycles up to 100% for light maintenance through heavy structural joining.
-
Broad Electrode Handling (1.6 mm to 6.0+ mm): Supports light rods up to extra-thick gauge industrial electrodes for high-penetration structural steel and pipeline fabrication.
-
Generator-Friendly & Complete Safety: Operates smoothly on generator power with integrated thermal overload, over/under-voltage protection, and optional VRD across Nepal.
