Wel-Handy Multi II TACK

product picture


  • Ultra-compact & lightweight -The 6.8 kg light weight unit gives improved handling and set-up.
  • Strong drawbar pull -16 kg magnetic force assures a stable motion.
  • Solid structure -Maintenance free aluminum die cast body makes it lighter and durable.
  • High speed operation -Maximum speed of 1500 mm/min can achieve high-speed welding
  • Low center of gravity design - Low center of gravity gives constant motion.
  • High clearance - It can run over weld beads easily.
  •  Easy data input - Tack information is digitally input and stored to ensure repeatability. Data is input by distance not time to ensure same welding length at different speed. It can include arc stable timer, crater time and crater fill distance in the parameters.
  • Digital display - Digital display shows actual parameters or welding speed.
