Despite the fact that I am the world ’s bad solderer , the liquid demarcation and features of this Cold Heat Soldering Tool still call to me . The AA electric battery - power atomic number 26 heat to 800 ° within a 2d , then back down to safe temperature within another one to five . Portable soldering irons are a fine estimation , but the butane - powered one tend to work better for recreational combustion than for actual body of work . At $ 20 , this battery - powered interlingual rendition might be deserving hold a barb . [ Thanks , Scott ! ]
