Features and Advantages

The most reliable & most portable welding machine offering best welding performance in its class.

250A Welding Current at 30% (40°C) - You will be able to perform un-interrupted welding also in intense welding applications with 5.0 mm diameter electrodes and 250A welding current offered at 30% duty cycle.

Overload and Thermal Protection Indicator Lamp - Thermal protection lamp will warn you in case of the machine enters protection mode due to overload.

Compability with Generator - Welding capability in environments without electricity due to its compatibility with generators.

Digital Ampermeter - It is possible to start welding operation with a more accurate setting after reading the adjusted current value from the indicator.

Hot Start Setting - You will never encounter arc ignition problems especially when welding on dirty or rusty parts and when using electrodes with moistured coating.

Arc Force Setting - Electrode will not stick to the workpiece any more or you will benefit from uninterrupted arc. Due to this feature, welding current will increase for a very short time and after the arc becomes stable it will automatically return to the adjusted value.

Lightweight, Small and Compact Design - Due to its new generation electronic circuit design, it is much more smaller than the welding machines designed with old technology and you will be able to carry your 250A welding machine without any need for a cart or wheeled carrier system especially in rough, narrow and crowded environments.

 

Arc-Force and Hot-Start

Arc-Force gives a power source variable additional amperage during low voltage (short-arc-length) conditions while welding. Helps avoid "sticking" stick electrodes when a short arc length is used.
Hot-Start used on Inverter 405-Ultra makes it easier to start difficult-to-start electrodes and used for arc starting only.
