PRO-PULS SPEED UI – genuinely fast in steel,<br />

efficient and with approx. 30% less <strong>welding</strong> fumes<br />

The new PRO-PULS SPEED UI pulse arc offers excellent results in terms of deposition rate and the resulting<br />

<strong>welding</strong> speed. The low-energy, but highly concentrated pulse arc gives you freedom of choice every<br />

day:<br />

up to<br />

30%<br />

higher speed<br />
