My $.02....take it for what it's worth. The heat control on these things is not very precise. It has multiple settings, but does not have any type of finger or pedal-controlled rheostat, hence you cannot fine tune the amperage, only use a choice of settings. (click, click, click-type control knob) As a rule of thumb, you'll need 1 amp for every .001 of thickness, so .049 tubing would need 49 amps. Go over that and you'll burn holes, under that and it won't melt. With a pedal control or thumbwheel, you can roll on the amps until you see molten metal, then weld. With this machine, I don't see you being able to do that.
Second, there is no gas regulator included, or a bottle. I would question wether it has an electric gas solenoid, also. Also, it is only 35% duty cycle. That works fine if welding a very small area, but try running a bead of any significant length and this machine will shut down. It ceratinly does not look like you can reverse polarity on this machine, either. That's a big consideration if you decide to weld other materials. Frequency, ie:Stainless? Doesn't say anything about that, either. Bottom line: If it looks to good to be true, it probably is. For $198, you'd be better off wiring two car batteries paralell and striking an arc with a coathanger. :-) That's my opinion, it's free, so consider it's value.
