Should you use a medium frequency controller with direct current welding?
Using a medium frequency controller with DC welding provides numerous benefits over alternating current (AC) welding. For instance, one of the biggest costs associated with using automated welding machines is their power demands. Aside from proper maintenance, this is a significant expense.
Why is MF based welding better than AC-based welding?
MF-based welding is less demanding on your power supply than AC-based welding because an MF inverter draws balanced line current during all phases of a weld. According to "Why Medium Frequency Welding", an MFDC welder provides "power saving of up to 35%" compared to AC-based welding techniques.
Do energy efficient MFDC systems have wider welding lobes?
Weld lobe have been generated with the experimental data and it was ensured that energy efficient MFDC systems has wider welding lobes at lower weld current levels as compared to AC systems.
Why is MFDC welding better than AC welding?
MFDC welding is superior to AC welding in several ways. It completes welds quicker, preventing much of the heat deformation and spatter typically associated with AC welding. The fact that the peak voltage of an MFDC weld is almost the same as RMS voltage further contributes to a reduction in sparks and spatter that are a given with AC welding.
What are the advantages of weld current?
The weld current has no zero cross overs so it heats the part quickly. It is DC so there are no inductive power losses or problems with magnetic material in the machine throat. Generally the plant power requirement is reduced substantially. Transformers can be reduced in size allowing better payloads for robot applications.
