• Pulse arc welder uses a pulsed current. It uses a
  cycle where a pulse current is repeated over a
  background current that remains the same

3
High Current Pulses

• Due to the pulse, the metal is transferred at low
  mean current levels by using short duration high
  current pulses.

4
Various Frequencies Bond Various Metals

• Frequencies from a few hertz to a few hundred
  hertz can be used to bond thin or thick metals. A
  wide range of equipment is available to meet any
  need.

5
Smoother Surfaces

• The result of the pulse welding is a smooth
  surface without any blotches. Less heat is used
  to weld the surface.

6
Welding at High Deposition Rates

• Where dip and spray transfers are not applicable
  pulse current allows welding at high deposition
  rates due to rapid cooling.

7
Great for Thicker Sections

• It is ideal for welding thick sections which
  require more heat. The mechanism is equidistant
  between spray transfer and the dip transfer.

8
Lesser Fumes are Produced During Transfer

• While other welding mechanisms produce more fumes
  during transfer, the pulse welding reduces fume
  levels generated by the arc.

9
Arc Heats up for the Transfer

• Pulse is also called spray pulse. The transfer
  is made when the arc reaches an energy level at
  which the molten droplets are transferred.

• Now that you know more about pulse welding you
  can look for a reliable pulse arc welder for your
  shop online.
