I have thought for years that the very large premium for inverter welders was not justified by cost differences. Note that some companies are offering inverter welders for price parity with transformer machines.

I am happy with my Syncrowave 200, but I can see the advantage of less current draw, and smaller size and weight, without doing a more detailed feature comparison.

But the introduction of the Syncrowave 210 may lower resale values of the Syncrowave 200 and 180, supporting my frequently expressed opinion that the best value for a basic TIG welder is a used Syncrowave 180 or 200.
