Topics Covered:

• Ohm’s Law in MFDC Systems – How voltage, current, and resistance interact in modern welding equipment
• Common Secondary Circuit Types – Overview of typical circuit layouts and when they are used
• Core Secondary Components – High-level look at bus bars, cables, shunts, and other key elements
• Transformer Sizing Worksheet – A simple approach to understanding how transformer size relates to load and performance
• Resistance in Materials and Grades – General review of materials used in secondary components and their effect on resistance
• Bus Bars, Cables, and Shunts – Their role in carrying current and maintaining circuit performance
• The Load Curve – How secondary resistance impacts the current output of a system at a fixed voltage
