Taking a step up from the 3938 in the Pro 86/88 pin-point range , the 3939 has the same 17mm diameter, but packs in a whopping 3.6 times more output. Its the perfect choice for all sorts of jewellery, gold and silver work, as well as soft soldering pipes up to 12mm in size. Silver soldering is possible up to a nice hot 615°C. This burner is 0.9kW, and the gas consumption at 2 bar is a very reasonable 70g/h. You can connect it up to your Pro 86/88 with the M20 x 1 threaded connection.
