The following items have been added to your list


The ET 186i AC/DC is a complete, multi-process TIG and Stick welding system. Lightweight and reduced in size for versatility and portability. Fully featured professional performance capability with variable controls for ease of use in a variety applications. HF Arc Start provides non-contact arc starting that eliminates tungsten or material contamination.



  • AC and DC output for aluminum and non-ferrous alloys, stainless, mild steel and chrome molys
  • AC Frequency: adjustable frequency of the AC square wave when welding on aluminum for optimized set up (15 Hz - 150 Hz)
  • Wave Balance: adjustable for optimized penetration or cleaning action when welding on aluminum
  • HF Arc Start: provides non-contact arc starting that eliminates tungsten or material contamination
  • Pulse: changes the weld current from high to low at a specified frequency, reduces heat input on thin material (0.5 Hz - 200 Hz)


  • Automotive
  • Transportation
  • Repair and Maintenance
  • Light Fabrication
