I have the IFL 200 phf. Very good mma welder but I don't know much about the tig side. I tried tig with it and the HF start went wonky, good thing its got a 24 month guarantee its only around 8 months old.
I've got one and I'm very happy with it (as it replaced an old 150A buzz box I would be ) If I hadn't bought it I reckon I would've given up trying to stick weld ages ago so it does exactly what it says on the tin really.
Got the 160 MA, very good machine, very pleased with it. Another chap at the railway club also has one, again he is pleased with it. Sneaked a look inside mine good build standard and very tidy.
