Resistance welding involves the generation of heat by passing current through the resistance caused by the contact between two or more metal surfaces. Small pools of molten metal are formed at the weld area as high current (1000–100,000 A) is passed through the metal. In general, resistance welding methods are efficient and cause little pollution, but their applications are somewhat limited and the equipment cost can be high.

Miller recommends considering power needs before purchasing a welding generator. Critical appliances to run during an emergency include well pumps (750 watts), sump pumps (800 watts), refrigerator (700 watts), air conditioners (2,500 watts) and radios (50 to 200). Note that many appliances take much more energy to start than to run. For information on running home appliances and tools, plus a power calculation worksheet and safety instructions, visit MillerWelds.com/products/generators.
