Been using Turbo torch, Victor's for around 37 years. This torch keeps up with the best of them. To be honest I didn't think it would last. For a third of the cost, it's a good buy
I have literally no idea what I'm doing when it comes to TIG but I watched a few videos and went for it. This box has absolutely no problem working with mild and stainless, and it's got enough flexibility with the settings to work with most setups. I'm currently running it off 110v and have had no issues with thinner mild steel. My only suggestion for improvement would be an increased post-flow time, as it currently maxes out at 6 seconds.
So I really like the machine but I use it in the field and it was just shy of 1 month before it stopped working completely now saying that I reached out to the manufacturer and they have not yet responded back to me so I will say don't by it Incase you have a similar situation.
