WELDMAX VERSITEC 550 MULTIPROCESS INVERTER
Weldmax Versitec 550 Multiprocess Inverter
The Weldmax Versitec 550 is a high-performance 3-phase multiprocess welding inverter engineered for industrial use. Whether your priority is extended duty cycles, process flexibility, or rugged consistency, this machine delivers. Choose between a standard gas-cooled configuration or an enhanced water-cooled package for even greater thermal stability under heavy use.
Key Features (Common to Both Versions)
-
Multiprocess Capability — Weld in MIG/MAG (manual or synergic), MMA (stick), and Lift-TIG modes
-
High Output & Duty Cycle — Delivers up to 550 A @ 45%, 500 A @ 60%, and 400 A @ 100%
-
Speed Spot Function — Precision MIG spot welding across various materials
-
User-Friendly Controls — Simple panel layout, parameter recall, 2T/4T selection, and adjustable settings (inductance, burnback, etc.)
-
Eco-Design & Efficiency — Built with power-saving, generator-friendly, and line-voltage compensation technology
-
Fan-on-demand & Protection — Intelligent cooling (or water-cooling), overcurrent/undervoltage protection, robust IP23S enclosure, Class H insulation
Package Options — Gas-Cooled vs Water-Cooled
| Feature | Gas-Cooled Version | Water-Cooled Version (Package) |
|---|---|---|
| Thermal Management | Air cooling via internal fan | Includes refrigerated water cooler for superior temperature control |
| Ideal For | Standard duty cycles, general fabrication | Heavy-duty, extended operations, high-current demands |
| Consumable Life | Good, standard under moderate load | Enhanced — cooler torch temperatures mean reduced wear and fewer failures |
| Noise & Environment | Typical fan noise and airflow | Quieter operation since the cooling load is shared with the water cooler |
| Package Includes | Versitec 550 inverter + wire feeder + controls | Versitec 550 inverter + wire feeder + refrigerated water cooler + necessary plumbing |
The internal specs, welding capabilities, controls, and features of both versions are identical. The only difference is the method of cooling and how well the system holds up under sustained high-output duty.
