Equipment Details

Whether in a shop or in the field, the Flextec 350X welder is built to perform.
Equipped with CrossLinc® technology, the Flextec 350X and 350XP welder can be controlled from hundreds of feet away without expensive and inconvenient control cables. Desert Duty® and IP23 rated, it can withstand harsh outdoor conditions and outperform other welders in its class.

In the field, the Flextec 350X Construction is a welder's most effective weapon. As a rugged multi-process power source, this model stays reliable and offers much more than other inverter-based welders in its class.

In the shop, the Flextec 350XP model is built to work with all 42V feeders for your factory applications. It is also compatible with Arclink® digital feeders to provide synergic modes, memories, and basic pulsed MIG for seamless connectivity and improved weld performance.

The Flextec 350X PowerConnect model adds the ability to weld with any input voltage between 200 and 600 volts.
