X 350

Light-weight high-performance champion.

Starting at a weight of 18.6 kg with 350 A, the X 350 leads the power-to-weight ranking. One could also say that it offers greater output at lower weight.

Rugged build.

The X 350 is extremely stable in spite of its low weight. Falls from heights of up to 60 cm are no problem thanks to its crash protection. The special construction of the base of the unit offers excellent shielding also protect from dust, water, and dirt ingress.

The high-voltage hero.

Extension cables of up to 200 m and generator operation are often required. The X 350 keeps on welding even if the voltage drops. The welding unit only turns off when the maximum negative tolerance of 40% is reached.

The smart energy saver.

Temperature sensors that steplessly adjust fan speed, the highly efficient MicorBoost technology and a standby function for welding breaks render the X 350 extremely energy efficient.

Country-specific product variants.
