I am looking at getting a Thermal Arc Arc Master 185 for frame welding and want to see if anyone had any time with this machine or an overall opinion about it. I have considered the miller dynasty 200 but have troubles with it costing the extra $$. I want to buy US but have problems with holding out till I can afford the miller, is it that much better? I should also point out that I want an inverter type welder but would be interested if anyone who has had time on both talk about their experience.
