EXPERT ARC 500 CELLULOSIC inverter welding machine 500A

EXPERT ARC 500 CELLULOSIC is a high power professional inverter welding machine designed for direct current MMA welding and direct current TIG welding with touch ignition. The unit is built for heavy industrial applications, ensuring a stable arc and precise current control even at maximum load. It supports rutile, basic and cellulose electrodes and is suitable for structural steel, stainless steel and cast iron welding. Electronically controlled stepless current adjustment from 20 to 500 amperes allows accurate configuration for demanding tasks. A clear digital display guarantees precise parameter control and stable welding performance.

The integrated VRD function reduces the no load voltage to a safe level, ensuring enhanced operator safety especially in humid environments. HOT START and ARC FORCE are manually adjustable, allowing fine tuning of arc dynamics.

Features
ARC FORCE regulates short circuit current and improves molten metal transfer while preventing arc extinction.
HOT START provides increased ignition current for easier electrode striking.
ANTI STICK automatically switches off welding voltage if the electrode sticks.
VRD ensures additional electrical safety.
Efficient fan cooling system improves performance and durability.
Built in overload protection increases reliability.
