I have no experience of either, but I would go for an Rtech mig due to there after sales service & 5 year guarantee. It’s a little bit more, but sometimes have offers & shop soiled machines & there are a lot of satisfied users on here. Just wish I had one!
No idea what their modern inverter ones are like, but based on mine I'd have to say don't. There are much better machines about for the money, Rtech has already been mentioned.
