Although in Russian here's a good video about testing cheap inverter based MMA power sources for Russian market. On low end(price) segment results should be generally similar, as there's no way around the laws of physics and cost of labor/components even in low cost countries.
In short conclusion all tested welders missed declared Hotstart and Arc Force features. The more expensive devices in the test had duty cycles and current max output currents corresponding to declared values. Lower priced 160 Amp model had actual duty cycle 10% instead of declared 40% at 40 deg C tested.
