No outside source of power is required ® ® when using ThermOweld . ThermOweld connections use the high temperature of reaction of powdered copper oxide and aluminum. The reaction takes place in a semi-perma- nent graphite mold (THERMOMOLD) that last for fifty or ® more welds if properly cared for. The ThermOweld reac- tion takes place in a very few seconds, therefore the total amount of heat (calories or BTUs) applied to the conductors or surfaces is considerably less than that em- ployed in brazing or soldering. This is an important consid- eration when welding to insulated cable or thin wall pipe. ThermOweld® is ideal for field use, since it is light and portable and requires no outside power source. It requires very little time or skill to obtain an efficient, maintenance free ® e
