The Ranger 8 now comes with a 20.5-hp Onan OHV engine, which provides a 6-percent improvement in fuel efficiency over the previous model. Oil changes and oil filters last twice as long. An automatic engine shutdown protects against low oil pressure, and an automatic engine idler offers greater fuel economy and noise control. The Ranger 8 is ideal for Stick, DC and AC TIG and general-purpose CV wire-feed welding.
