Great piece of kit, exactly what I needed and works like a charm. I needed to modify the supplied copper electrodes as I needed narrow access but this was really easy and resulted in a perfectly set up tool which does a brilliant job. I am welding narrow 0.4mm stainless strips onto a 2mm thick stainless turned component and on the lowest setting the welds are beautiful, neat and totally secure. Other lower power spot welders failed this task due to the thickness of the 2mm base, but not this one. In use the welder is adjusted easily for different tip pressure and makes a slight squeak as it welds and its over in a fraction of a second. Its brilliant value for money and is perfect for me, I couldnt get even a 2nd hand one for this price and the delivery was so quick, just a couple of days after order. So pleased!
