Dewalt and Esab partnered together to produce a new FlexVolt-powered cordless welder.

The Esab Renegade Volt ES200i is powered by (4) Dewalt FlexVolt batteries.

When equipped with 12Ah batteries, the Dewalt-powered Esab cordless wleder can burn up to 33 (E6013) electrodes per single charge.

It can deliver a output of 200A on 230V AC power, or up to 150A when powered by Dewalt FlexVolt batteries.

The welder features an AMP+ hybrid power mode for extra power. In this mode, the Renegade Volt welder supplements AC power with battery power, to “prevent nuisance trips on smaller breaker sizes,” or to “provide more output when welding on 120V input.”

It can be powered by 120V AC, 230V AC, Dewalt batteries, or AC + battery power in the Amp+ hybrid mode.

Esab describes the new welder as having the “first power source with no limitations.”
