Pulse MIG welding mode, “ PMIG ” PMIG enables getting high quality aluminum products. In this mode, on the main current will be superimposed transient current pulses and providing a rapid melting of the wire. As a result, the metal has no nodules. The MIG pulse also carries out a crushing crystals melt zone and form a tight seam quality. In addition, all the impurities are blown out of the weld pool. Adjustable heat input improves the quality of welding thin-walled metals. This prevents overheating of the aluminum to ensure the metal does not warp. It also decreases spatters and improves geometry and appearance of the weld joint. PMIG is indispensable for welding stainless steel, aluminum and other nonferrous metals which are sensitive to heat input.Double Pulse MIG welding mode, “ DPMIG ” DPMIG is the main feature of the Topwell ALUMIG-250P Double pulse Synergic. During the welding process, there are superimposed with the two levels of the pulse current on the arc current. The high pulse period "drives" welding and "drops" in the melt zone, and the low period makes it possible to cool the metal to avoid distortions and sags. This ensures full control and temperature control in the zone of the arc, which ensures perfect welding "stacked-dime" seam, as same as in a time-consuming TIG welding. In the Double Pulse mode, it is available for setting the pulse duration of the operating cycle with high current in the range of 10% to 90%. This ensures optimal heat input and perfect transfer, which improves the quality of the weld. It’s also available for setting the pulse frequency in the range of 0.1 to 10 Hz. DYNAMIC CONTROL Dynamic Control is to
· Increase or decrease the arc length.
· In Double Pulse Mode, adjust Dynamic Control to increase or decrease the space between the ripples. SYNERGIC MIG
Synergetic control algorithm greatly simplifies the process of setting up the welder. Thus the welder is enough to choose the diameter and material of the wire depending on the thickness and kinds of the base metal. Other parameters will be automatically selected by the welder itself. With Built-in database of different welding conditions, it don’t need to adjust every parameters. You could only set the current, then will pick up the rest of the system itself. If necessary, you can do some fine adjustments for a greater welding experience and result.   Company Information COMPANY     FAQ Q:Are you a factory or a trading company?
