Product Code
- Product group:
- 191
- Product number:
- 503503

UWI-Maximus 503 is a powerful welding inverter for all arc welding (Stick/TIG/MIG/MAG) & gouging processes onboard. The new generation welding inverter is both lightweight and portable, ideal for maintenance and repair work onboard vessels requiring high duty cycle welding. It can perform wire welding with the combination of UWF-513 wire feeder.

Product information
This product supersedes product no: 670398
EU Ecodesign Compliant Welding Machine
The welding machine is supplied complete with accessories i.e. electrode holder and return clamp.
Features
- Stick electrode (MMA) with adjustable hot start and arc force for optimal welding properties
- Lift-Arc TIG welding with remote control option for all welding processes, with total arc control both during welding and for the down-slope finish of the weld. Adjustable gas post-flow prevents faults in the end phase of the weld
- Two machines can be linked in parallel for up to 1000 Amperes for Air Carbon Arc gouging
- Voltage Reduction Device (VRD) function reduces open circuit voltage to only 12 VDC which reduces risks of electric shock and electrocution to the lowest level
- Built-in Total Protection (TP), Line-voltage compensation and Thermal overload protection
- Made of high-grade aluminium casing that reduces weight and corrosion risks
Benefits
- Safe and compliant welding machine for maritime use with higher efficiency and lower power consumption
- 10-500A current range covers the use of any size of welding electrodes and two machines can be connetced parallel to provide 1000A
- Multi-process welding with combination of UWF-513 Wire Feeder for wire welding
- Heavy duty and superior reliability in tough maritime environment
- Spare part kit available easy repair and to minimise downtime when at sea
