Delivery within 48 hours after the order, parcel arrived one day in advance, what a surprise. As for the apparatus, the power son has white spots is infact the packaging polystyrene which stuck on the wire. Why? humidity, heat in the containers? This will explain the blue smoke coming out of the iron when I have connected and set the thermostat to 50%. It works but it emmet a transformer burning smell, smoke through the vents holes iron and changed color in 3 minutes, it went from chrome brown / black. Some say it's normal, it would be oil that has served to raise the burning. After a few minutes of heating and welding smoke disappears gradually. The rest of iron appears solid, although the base is hard plastic and is very massive. It seems robust in general. Good buy, recommend
