Q&A:
Does machine complexity prevent upgrades
to industrial equipment?
Solution: With built-in inverter technology, the Millermatic 350P
maintains ease of operation while handling industrial-grade
applications including MIG pulsing.
Are thin-gauge applications out of reach?
Solution: The Millermatic 350P was built with thin metal
applications in mind. Adaptive pulse technology reduces total
heat into the metal and improves bead appearance. Sharp Arc
further enhances welding of thin-gauge metals by precisely
“We use .040 gauge aluminum for our trailer
roof skins and were amazed that there wasn’t
any burn-through with the Millermatic 350P.”

Would you benefit from having the flexibility of
three-phase power input?
Solution: The Millermatic 350/350P is the only machine in its
class that offers the flexibility of both 1- and 3-phase power
inputs. 3-phase power delivers the added benefits of increased
energy efficiency and lower utility bills.
