TOPWELL pulse on pulse MIG/MMA Welding Machine ALUMIG-300P with 300 amp pulse mig welder

Pulse MIG precisely controls heat input through the
1-drop-per-pulsetransfer and offers a stable arc in the
wide transfer area between short and spray arc.
Spray arc transfer “sprays” a stream of tiny molten
droplets across the arc, from the electrode wire to the
base metal.It produces a characteristic humming
or buzzing sound.

Advantages of pulse mig:
• High deposition
• Good fusion and penetration
• Good bead appearance
• Capability of using larger diameter wires
• Presence of very little spatter

Synergic pulsed welding mode offers the simplicity of
single-knob control.The machine will select the correct pulse
power based on the wire feed speed (WFS) set by the operator.

Begin and end welds with ease and confidence.Hot start
eliminates incomplete fusion at the beginning of a weld,
a common issue with aluminum welding.Crater gradually
decreases weld current at the end of a weld to eliminate
crater defects.Adjustable pre- and post-flow rates ensure
that the puddle always has adequate gas coverage.
