Excellent product, performance above expectations, the possibility of adjusting the impedance helps a lot in welding thin sheets.

Very high quality product. I recommend!

This is a very good device and powerful, at the same time many settings, welds evenly and stably down to 0.9 millimeter thick plate no problem, the only thing that makes the experience bad is that there is no good user manual for use and how to set parameters on the device there is not a word about what the different settings should be set to for ex with gasless welding without gas with o.9 mm wire, then it says that you don't need to adjust anything just set it to manual mig gasless and wire diam , so there is a lot missing in terms of use and I, who know a good deal about me etc, feel that it is frustrating to have to spend hours on adjustment and a huge amount of waste of wire, so it is not just to set these parameters and then weld for when I started with manual mig gasless and 0.9 mm wire then I tried to weld but the wire didn't stop welding until 5 seconds after I released the switch and it was so annoying to have to search through all 16 different settings to eliminate this welding error, furthermore, I also had problems when I tried again to mig in manual mig without gas because after I tried to set this type of mig welding then now when I stopped welding the wire inside the nozzle stopped and burned inside, so again was it just a guess as to where I should adjust, so actually there was a lot I had to adjust for use in manual gasless welding, and the output for manual for me says that there is no adjustment in this mode, you just have to set it to manual and gasless and wire thickness then it was just a matter of welding but it doesn't match so in any case the user manual is very poor, and full of many, no concrete table in the various settings so you spend far too much time looking for a perfect welding seam, and you have to jaggu sit down to create a common user manual because otherwise you will lose customers quickly in order to be able to provide the right service you should be able to create a correct manual for all devices and all the different types of welding and values at all the different levels, it shouldn't be difficult to show all buyers that there are settings for all types of welding and what the numbers should show for the different ones, so I hope they find a better solution

A very good welder at a reasonable price. The downside is that there is no detailed information about Synergy in the manual and relatively little detailed information can be found online. No video etc. However, the device's interface is really simple, so after a few tries you know what to do and how to do it. The device is semi-automatic and handles all basic connections really well. Two rollers guide the wire smoothly. it is completely sufficient for smaller spools. They have quite good pushing power, because even if the cable is bent etc. I didn't encounter any problems with smooth driving. The housing is solid and looks well-made. Express shipping, product delivered the next day, well protected. 160A seems to be very realistic, I previously had another welding machine bought at auction with a higher A, but this one is much more efficient. So I bet that these are real data. To sum up, I am very satisfied, I recommend it.
