Read about MIG and TIG Welding and see pictures of different types of welders, gloves, and diagrams, inside Rod & Custom Magazine.

The 140 lets you work thicker materials, and can also be used for MIG welding. DISLIKES: Not as heavy-duty as the Miller or Vulcan, so better left in the shop than taken to the job site.
