The biggest issue you are up against with transformer technology is poor duty cycle compared to that of inverter technology.......
Haaaa inverters go wrong>>>>com'on nothing knew with inverters my first was in 1990, rock solid industry working machines now.. the only thing inverters dont offer is a free hernia and gold club membership to the grid...
Well here's this months list of repairs Snowy:-
Murex Sabre Arc 35i Plasma...HF Board
Kemppi PS3500...Mother Board
IFL 200HF...Mother Board
Cebora Bi-Welder 1365..Right off
Selco Genesis 140...Right off
Pretty broad range of makes there, all regarded as decent kit, all Inverters, and all kaput!
So yes, they do indeed go wrong. Mind you so do transformer based sets, it's just that they are easier & usually cheaper to repair.

All the stuff listed are reputable manufacturers, so I guess it makes the purchase of an inverter based TIG a bit of a lottery …………also the suggested spares holding from ESAB does suggest that inverter technology in welding may not be quite ‘there’ yet.
And I would like the phone number too
Also do any of the transformer machines have "Pulse" ??

My Airco has no circuit boards; the only electronic part is the diodes. Many Dialarcs are the same (Miller made the Airco and copied the design for the Dialarcs.)Ohhh and I had a PCB fault on the H/F head a few years back 300 big ones to get it fixed, Its a myth that transformer machines are cheep and easy to repair.
Probably because the market is flooded with cheap inverters that fail.I still feel im missing the point, 18 years of useing inverters and no more problems than something with a transformer, I fail to understand why there thought of as unreliable??
Freinds have had the same experiance....also
