MMA welding is a simple yet universal, inexpensive and portable welding process. Flux coated welding rods are used, eliminating the need for bottled shielding gas like that used in MIG welding or TIG welding. Stick welders are ideal to use when welding outdoors and/or welding objects that are rusty or dirty. Most common metals and alloys can be joined using a stick welder. Choose from a variety of i-WELD stick welders, including some that also offer TIG welding capabilities for more universality. Product comparison is available on product pages.
