Voltage adjusting range of 220-240 (v) rated welding current 0.1 km (a) Use flux-cored wire diameter 0.6-3.0 (mm) HL-B01 no lead iron is a paragraph durable and affordable of iron, power: 40W,60W; using stainless steel tube do fixed took over; using specialist life fever core do fever source, by theory (in normal voltage Xia, continuous power time for 1440 hours) and actual test (in work in the normal voltage Xia, continuous power time for 1440 hours, that work power, and work power time) average using life up 1440 hours above. While configurations durable lead-free soldering iron mouth.
