What is the Pulsed MIG Welding?
In simple terms, pulsed MIG is a non-contact transfer method between the electrode and the weld puddle. This means that at no time does the electrode ever touch the puddle. This is accomplished through high-speed manipulation of the electrical output of the welding machine. It is designed to be a spatterless process that will run at a lower heat input than spray or globular transfer methods.
The pulsed MIG process works by forming one droplet of molten metal at the end of the electrode per pulse. Then, just the right amount of current is added to push that one droplet across the arc and into the puddle. The transfer of these droplets occurs through the arc, one droplet per pulse.
Advantages of Pulsed MIG Machine:
● Wire and gas saving: Pulsed MIG machine offer a wider operation range because they extend the low and
high range of each wire diameter.
● Spatter and fume reduction: Compared to conventional MIG machine, Pulsed MIG offers reduced spatter and
fume Reduction in spatter translates into significant cost saving because more of the melted wire is applied to
the weld joint, not as surface spatter on the product and surrounding fixtures. This also means less clean-up
● Heat reduction: Pulsed MIG offers controlled heat input leading to less distortion and improved overall quality
and appearance which means fewer production problems. This is especially important with stainless, nickel
and other alloys that sensitive to heat input.
● Improved productivity: Pulsed MIG offers high deposition rates. In addition, since the new models are
simplerand adaptive, it is easier to welding with Pulsed MIG than other transfer methods, less time is spent
● Better Quality: Pulsed MIG offers better quality of the finished and a more stable arc. Synergic power sources
allow for these high quality welds to be achieved by those with relative less training.
How to choose Pulsed MIG Machine:
● Choose machine capable of operating over the new expanded
range of welding processes
● Look for advanced synergic controls
● Consider investing in dual procedures guns and spool gun
● Carefully choose welding gun size
● Look for work voltage sensing if welding far from the power source
