UNIDRIVE Semi-Automatic Welder

The compact UNIDRIVE 500 semi-automatic welder is the innovative successor to the TRIAC DRIVE. Guided by two handles, welding pressure is evenly applied to ensure quality welding results. Changing direction couldn't be simpler! A simple nozzle rotation and the press of two buttons changes the direction of the drive motor. The UNIDRIVE 500 welds every overlap, even if space is tight, three times faster than manual welding. Overlap welding with the UNIDRIVE 500 – safe and economical – everywhere. 
  • Closed-loop temperature control ensures consistent temperature and reliable weld quality even with voltage fluctuations 
  • Three times faster than manual welding
  • Reversible drive allows for welding in either direction
  • Ergonomic handles apply even pressure 
  • Intuitive user interface with large display 
  • Maintenance-free, brushless motor
  • Compact and lightweight: 4.5 kg (10 lbs), 30 cm (12 in.) tall

Why Buy From Us

The UNIDRIVE is available in Canada only through STANMECH and our distributor network. Tools bought through us are electrically certified for use in Canada. In many cases this entails replacing cords or switches in the tool to meet stringent CSA standards. Each tool is physically inspected by an approved field inspector prior to certification. We offer same-day shipping on in-stock items from our facility in Burlington, Ontario, Canada.
