Fabrication

Welders

Harbor Freight examples spanning dedicated flux-core and multiprocess machines. Compare processes, input power, and duty cycle at the output you need.

Before choosing your setup

  • Match the process to the metal and joint you plan to weld.
  • Check input voltage and circuit requirements in the machine manual.
  • Compare rated duty cycle at a stated amperage, not maximum output alone.
  • Check the included torch, regulator, cables, and any optional spool-gun or TIG accessories.
