Hello All Somewhere online I read and I can''t remember where, that several smaller value multiple capacitors are used in our mig welders as opposed to fewer larger value caps to accomplish better heat dissipation and to distribute this heat over a larger number of caps. This would seem to make sense. For example I have three different migs one is a 300 amp

With only 14 x 10000uF capacitors in the circuit (close to the capacity of the 142500uF capacitor bank in the original project) I am able to weld strong joints with .1mm pure nickel strips at 26V, and .15mm pure nickel strips at 28.5V (3kA). I have 14 square mm of cable to each probe ((doubled up AWG10 (3mm dia.) silicon copper cable)), so resistance is negligible.

Capacitive welders deliver repeatable welds even during line voltage fluctuations. Spot welding relies on the principle of metal resistivity to heat and fuse metal. A large current is passed through the work piece. Energy is dissipated due to the metal resistance in the form of heat which melts and fuses weld materials. There are two phases to
Capacitor Discharge Resistance Welding is a welding process ideal for mass produced products in the automotive, appliance, and electrical sectors*. The controller in this process features an extensive data collection system capable of storing 100,000 records, including graphs and important parameters, and the complete welding program.*
Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material. The heat affected zone, where the properties of the metal have been changed from rapid heating and cooling, is localized to a small area around the weld spot.
Capacitive resistance welders have many advantages. Weld nugget formation takes place during the first few milli-seconds. Capacitive discharge welders allow extremely fast energy release with large peak currents. More of the energy goes into weld formation and less into heating surrounding material.
