A lightweight inverter electrode welding machine. Suitable for rutile, basic, stainless steel, and cast iron electrodes. TIG welding is possible. Equipped with Arc-Force. The Arc-Force control monitors the welding current and voltage. This monitoring allows for quick resolution of short circuits during droplet transfer and prevents the electrode from sticking while welding. Thus, even coarse-droplet electrodes can be processed without issues. Equipped with a Hot-Start function. Hot-Start is an ignition aid for starting the arc of a stick electrode during electrode welding. The automatic, temporary increase in welding current ensures that the arc ignites stably right away. Equipped with an Anti-Stick function. In the event of accidental electrode sticking, the welding current is automatically reduced. This prevents the electrode from overheating. The stick electrode can easily be detached from the workpiece when the Anti-Stick function is activated. Protected against overvoltage, undervoltage, and overload. Cooling is provided by a fan.
