New Pulsed MIG technology provides superior arc starts by automatically providing more energy at the start of the weld, which helps ensure good fusion and then reduces energy to normal parameters for optimal welding characteristics.

Greenheck Fan discusses the advantages of Pulsed MIG welding on aluminum 

The greatest challenge with welding aluminum is that it is easy to burn through and/or cause distortion. The key benefit of Pulsed MIG welding in this application is the balance between providing sufficient energy to ensure good fusion yet controlling heat input to prevent warping or burn-through.

Working with Pulsed MIG equipment has allowed Greenheck to eliminate its reliance on .035 inch wire in certain applications and transition to 3/64-inch (.047 inch) aluminum wire.  The larger wire diameter allows for faster travel speeds, increases fill rate (deposition) and is a lower cost per pound.

The Invision 352 MPa features built-in Pulsed MIG programs for common 4000 and 5000 series aluminum wires ranging in diameter from .035 to 1/16 inch, as well as many of the other alloys found in Greenheck’s products (steel, stainless steel, silicon bronze, copper, nickel).

Greenheck air movement and control equipment is used in commercial, institutional, and industrial facilities, ranging from comfort ventilation to manufacturing processes.
