That reminds me actually Eddie is there any evidence of this ? I did try a search and found nothing......
It's just illogical that there would be such a high minimum current on an inverter power supply. It is really silly that the suppliers quote these numbers, since people who know what they are buying and want to weld thin metal will be put off, thinking the minimum is too high for their needs.
As an example, the Blackline 200A inverter MIG quotes "50A", but when 8ob reviewed it the lower limit was about zero:
https://www.mig-welding.co.uk/forum/threads/blackline-200-amp-mig-mag-mma-arc-welder.94372/
"Lots of Chinese MIGs have these type of numbers in their specifications, or printed on the data plate. I think that this is a mistake.
It is an inverter, controlled by a potentiometer labelled 0 to 10. I'm sure that if you start welding with the power control set at 0, the current will be less than 20 Amps."
"Spot on Eddie, tried it tonight and 0 is virtually no amps/volts."
Similarly, my Uptime MIG 160 has a dataplate that states "50A to 180A" , but with the control set at zero, the built-in digital ammeter reads 0 Amps. Turning it up one division on the 0-to-10 scale, the meter indicates 5 Amps.

Well to be perfectly honest, in my opinion neither of those posts or any of the links off them show any thin metal been welded.
The 0 - 10 scale on the dial just indicates that when it's turned unto 10 it's a higher setting than when it's set to 0.
I'd like to see some pic's of say 20 gauge steel butt welded together with one of these machines, a video would be even better.
With the added bonus I could stop saving up for a Porta Mig and buy something for about a quarter of the price.

Something like this would be good. https://www.weldequip.com/ifl-170-mig.htm

Hey everyone,
So, some time has gone by and I ended up buying said machine.
I tried it for the first time today, with 6mm wire and 100% CO2 at about 14 (cant remember the unit's name).
Have in mind I've never welded before, and have never been around a welder so, this is totally new for me.
Welder seems to work great, no issues at all during the 15m or so I used it.
So far, great investment
Feel free to comment on my attempt at welding.

Not too bad.... I can see 4 good beads on there!
I am not sure what the metal is, looks like a piece of flattened pipe?
Best to practice with a sheet of clean bright shiny new steel, of the same thickness that you will be using later - e.g. 1mm for car body repairs. Cut some handy-sized squares and rectangles ( "coupons" ). Start with straight beads on the surface, from 1 to 5 cm long, if the welder will do that without burning through. If burn-through becomes an issue, then go for 2mm sheet initially.
Then progress to lap and butt joints and plug welds ( which simulate spot welds, with an 8mm hole in the top sheet ).

Canpoo I'm from Porto too. I'm also in the process of buying a MIG welder. I was looking further into Sherman, Telwig and Stahlwerk welders in the 180A-200A range, but now reading this topic I came across Rohr which I didn't know anything about. How has been your experience with this welder so far? Any downsides I should know of?
