سؤال: I wanted to calibrate the display to show actual current and turned vr1 potentiometer on main PCB. It is wrong potentiometer. What is the original setting value? I am afraid that welder will brake since bad setting on vr1, please share correct setting. Thank you.

hitman247 Scesc, I have bought this welder, but unfortunately turned the vr1 potentiometer on main board upside, can you please tell me the original value so I can set it back? unfortunately my welder does not have the trimmer for calibrating display, only fixed resistor or maybe entire small PCB from under display is missing, not visible good enough. thank you

Very good welder for the money. It strikes the electric arc nicely, stably maintains the set parameters and, above all, welds nicely and is very small. The only drawback that bothers me personally is the highly inflated parameters. At the maximum intensity that the manufacturer specifies at 250 amps, the welder gives 132. I took measurements and at the maximum settings it is 130 amps, and at the lowest 56. The welder is perfectly welded with 2.5 and 3.2mm electrodes. With a little experience of the welder, it is possible to weld with a 4mm electrode. In my device, I changed the welding current display range to real 132 amperes. This can be done with the potentiometer marked in my photo. If the manufacturer did not overestimate the parameters, surely more people involved in welding would be interested in this device. After minor modifications, this welding machine is an ideal device for DIY enthusiasts and people who weld on a mobile basis. Sorry for the translation, but I did it in translator.

10 gün gibi kısa bir sürede Aras kargo ile evime teslim edildi, vergi dahil kargo ile aldığım için ekstra başka bir para ödemedim, cihaz güzel açıp söküp içine baktım kaliteli parçalar kullanılmış, ne kadar dayanır bilemem, evimde kendi işlerimi görmek için hobi amaçlı aldım, içinden kaynak maşası ve şase maşa ve kabloları çıkmıyor bilginiz olsun, bu fiyata uygun bir alet kaynak testini de yaptım başarılı bir ürün..
