It's what I mentioned about modern power supplies, an inverter welder is a SMPS (Switched Mode Power Supply).? It converts the mains power to DC.? Then Switches that at a high frequency.? This means the transformer is much much smaller.? You won't find big iron transformers in these, just small ferrite (a magnetic ceramic) transformers.

I remember when these first came out, I worked at a MIL testing lab in the USA.? We were amazed but concerned that the output voltage wasn't quite as clean as our big, boat-anchor sized, linear power supplies. On 10-Feb-25 19:13, davesmith1800 wrote:
