I have had a Rtech 30A plasma cutter for around 7 years I haven't used it a lot but it has never missed a beat. My son took it to make holes through a RSJ to get pipes through and he said it did it without any problems.
I'd rather spend my money in something more capable if in yours .
I have a blowback pilot arc start 35A plasma cutter .
I've used only once, got brand new for a discount price of only 180 euros
Instead of 580 euros because it was the last one of the badge and they were struggling to sell it .
Anyway it really struggles getting a nice cut over 8mm .
It has s trafimet s45 torch, PFC, enclosed regulator.
Very compact overall a nice unit but not what I need.
Although I've cut a cutting edge off a small bucket so it's kinda fine but .
If I have to pay around 600 euros I'd go for a completely different machine .
Like an Ideal profi 55pfc which is capable of 28mm severance cut just like an hyperterm power max 45 xp.
Anyway if I could go back I'd save the 180 euros and use them to buy missing bits to complete my oxy propane rig which I'd find far more useful for my needs
