Review : In this article I am talking about the fuel injection model. The carburetor model is almost the same in operation. This is a great machine for portable welding and even for hobby welding. It is a commercial level thing. It is a multipurpose welder. It can run as a power source for constant current and constant voltage application . Stick, MIG, TIG, Flux cored anything can be used. TIG torch can be attached very easily to the welding lead. It does have a switch right on the front side which gives you TIG, Stick. It also has AC and you can run your 6011 easily on the AC. Both 225 and 250 and EFI all come with the AC mode. It also has a wire positive and negative line. Flux cored or wire both can be used. And all those things can be controlled from one machine. It has a nob for selecting the current range (40 - 130 amp). And then there is the nob to fine tune the current again. Miller has a great job! On the front side there are some flaps. Underneath them you will find connection for your work and electrode. It has 220 output with a 50 amp breaker on it. It has four sockets for regular 120 Volts. Plasma cutters can be added to this. So this is a full functioning completely portable welding machine from this one power source!  It got a little table on the front underneath the door which work as a reference or cheat-sheet for the newbies. On the top Electronic Fuel Injection module cycle. When it is turned on the lights on the top is on which is metering device or fuel gauge. The light will go off if you have any problem. Fuel injection module has start, run/idle and run options. After run option is applied it shows the hours that are remaining for the next fuel change. Once the oil is changed you can reset the module. On the carburetor versions their is a chock nob instead of this EFI module.  On the bottom there is the induction fan for air intake which is actually blown out of the top.  The exhaust line is a short one but it is very quiet. There is a fuel meter on the side. The fuel tank should not full to the brim for some reason. But it actually gives a great run time. The finish is really awesome. The main engine opening door is quiet easy to open. There is a top door for checking the air cleaner, oil filter and oil level indicator. On the back there is the battery. It is cheaper than the Lincoln welders and it has EFI so you will definitely save $500 if you buy this ! It produces 12000 Watts power. When You want to have highest generating power make sure that the fine adjustment nob is set to 10. You will have the ability to weld and run the generator at the exact same time.
Some notes on EFI :    EFI gives the super ease of starting (Really awesome !!). When not welding no fuel is wasted. When welding starts the EFI automatically starts functioning. It saves a lot of power. See the video below it will understand it !
