MULTI-PROCESS WELDERS
Invertec V350-PRO Designed Smart. Built Tough.
® The multi-process Invertec®
• All input voltages and frequencies are both single and three phase rated—no phase derating necessary on single phase.
• 5-425 amp output range for all recommended processes from DC TIG to arc gouging.
• Input voltage from 208-575V—this one machine is capable of running on virtually any input power supply.
• 50 and 60 Hz operation—can be connected anywhere in the world. • Touch Start TIG®
for contamination-free starts.
• 88% efficiency—low power consumption for energy savings. Product

This multi-process welder delivers up to 500 amps of welding power for a variety of applications, including construction and fabrication. It features an IP23 rating for outdoor operation and storage, and the latest inverter technology will save you real dollars on the utility costs associated with your welding operations.
• Flexible Multi-Process Capability – Including stick, Touch Start TIG® flux-cored welding and carbon arc gouging with up to a 3/8 in. (9.5 mm) carbon.
(DC), MIG, • The Future is NowSM – You no longer have to pay a price premium to
gain the advantages of inverter technology over conventional welders. - Faster Arc Response, Low Power Consumption and Enhanced Portability.
• Compact, Durable Case – Tough IP23 enclosure rating for extreme field environments.
• Selectable Hot Start – Turn it off for thin material or flip it on to get the extra starting amperage you need for thick, rusty or dirty material.
• Variable Arc Control – In stick mode, vary the arc force to obtain a “soft” or “crisp” arc. In CV modes, vary the pinch or inductance to control spatter, fluidity and bead appearance.
• Full-Featured Remote Control Capability – Use a foot pedal or hand control to remotely vary output up to 100 ft. (30.5 m) away.
• Desert Duty™ Rated – Welding outputs are rated for extreme
temperature operation up to 55°C (131°F). Product
