PATON™ PRO-350-400V Inverter Welder
The PATON PRO-350 400V MMA/TIG Lift welder inverter is designed for manual MMA arc welding, argon shielded TIG arc welding with direct current, and semi-automatic MIG/MAG welding with shielded gases and protective mixtures.
This model achieves a duty cycle of 70% at its full nominal current of 350A, which is sufficient for working with any electrodes from ⌀ 1.6mm up to fusible ⌀ 6mm, as well as semi-automatic welding with solid wire from ⌀ 0.6mm to ⌀ 1.4mm (MIG/MAG welding is possible after purchasing a wire feeder). The device is set to optimal values for most use cases. Demanding users can select each parameter individually.
The PRO series offers full electronic control, which allows greater control of the welding process for each selected method, as well as enabling the maximum potential of the equipment. PRO series welding inverters are dedicated for industrial use, as well as for the most demanding home users.
The main advantages of the PATON™ PRO-350- 400V MMA Inverter Welder
- European production of welding machines
- Electronic thermal protection system that protects all heat-generating components from overheating
- Possibility to connect an external wire feeder
- Possibility to work with long extension cables as well as with a generator
- Availability of pulse current welding mode in all methods
- Improved arc glow stability
- Hot-Start , Arc-Force and Anti-Stick functions
- The devices, in addition to protection against line voltage spikes and dips, have a system for stabilizing operation during prolonged changes in phase-to-phase line voltage and enable proper operation for the voltage range from 320V to 440V
- Twice lower power requirements compared to traditional sources
- Optimal fusion and correct stitch shape regardless of welding position
3-year manufacturer’s warranty for consumers as well as companies
