Why welding shops use ATI

Get the machine back on the line

Older welders, still earning

The welder runs fine for years, then a power module fails and the maker has moved on.

At ATI: discontinued power semiconductors are most of what we sell, from 30+ manufacturers.

Tested before it reaches us

A bad part means another teardown and more downtime.

At ATI: parts are tested by our supplier before they ship to us.

Crosses and equivalents

The exact module is gone, and the job is waiting.

At ATI: ask us for a compatible equivalent and we will check it across manufacturers.

Stand behind it

You need a supplier who answers when something goes wrong.

At ATI: every part carries a 1-year warranty.
