  • 3 Phase MIG Welder

    Industrial strength and ready for heavy welding applications in the shop.

  • Auto Switching

    To switch welding different base metals, simply pick up the appropriate torch and pull the trigger, the microprocessor and weld programs do the rest.

  • Double Pulse

    Safely and confidently repair aluminum and steel with automatically controlled pulse welding.

  • MIG Welding

    Features three MIG welding torches and wire spools. Also includes preloaded weld programs and synergic curves for all common welding situations in automotive repair.

  • Multiple Welding Processes

    Accessing multiple applications is as simple as pressing a button and making your selection.

Auto SwitchingBack to top

  • Simply pick up the appropriate torch for the base metal you want to weld and pull the trigger — the SP-5.3 will automatically switch the weld program and synergic curve — no need to change wire spools or shielding gas.

  • Aluminum MIG Nozzle
  • Silicon-Bronze MIG Nozzle
  • Steel MIG Nozzle

  • SP-5.3 3 Wire Spools

    Preprogrammed synergic curves maintain optimal arc stability and weld quality.

  • SP-5.3 Open Side

  • With three wire spools dedicated to three separate torches, the SP-5.3 is capable of easily switching between Steel, Aluminum and Silicon Bronze welding materials. This gives the operator seamless transitions from material to material and increased work flow which leads to a faster cycle time.
