Ajax TOCCO Magnethermic recently delivered two 5- /10-kW induction heating systems to an international heat-treating firm. These systems are designed for portable, on-site preheating prior to welding applications. The company chose these systems over larger 35-kW induction heating systems. At 5 kW continuous output, the systems satisfied the majority of the company’s small to medium applications and were capable of heating 50 kg of steel to 200°C in 30 minutes. The 100% air-cooled design also includes quick setup.
