It is an unquestionable fact that welding aluminum items calls for professional expertise and special skills of MIG welder. Welding enthusiasts who have past experience in productively welding steel will find aluminum welding demanding. The reason is simple - it is complex to supply aluminum wire which is soft. Additionally, wire diameters and machine settings usually used for steel may not be suitable for aluminum.
MIG welder for aluminum is different from welding steel and this also applies to shielding gas requirements. For aluminum, 100 percent argon is the favored alternative, whereas steel welding calls for a mixed gas. Of course, for this reason no particular equipment is needed - your obtainable regulators and gas hoses can be used for both pure blends and mixed gases.
MIG welding on aluminum materials necessitates electrode positive polarity. If you are switching your wire feed welder between processes, do not forget to switch your polarity. It is best to use a new wire brush that hasn't been used on steel, and to brush in a single direction.
