Merlin Control Systems has developed a version of the PWC8 range of weld control units that is suitable for multiple transformer machines, or more complex DC machines. The PWCx3 controller features three independent control circuits in one printed circuit board with the facility to individually control three transformers, which can be on the same phase or on different phases of the mains supply. This offers a more compact, easier to use and less-expensive means of controlling multiple transformer welding machines. Different configuration options are standard for this controller, so the same unit can also control a three-phase or polyphase DC machine at a much lower cost than is usual for this type of machine, according to Merlin. As with all Merlin weld controllers, versions are available for simple manual operation and setup, or for communication with a higher-lever PLC-based control system. Different program sequences are available to suit spot, projection, seam and butt welding mac...

Sola/Hevi-Duty offers a broad range of transformers to meet many applications. These dry-type transformers are offered encapsulated, ventilated or non-ventilated, 600 Volt Class, isolation type, single and three phase, through 500 kVA. Indoor and outdoor models are available. General Purpose Transformers can be located close to the load. No vaults are required for installation and no long, expensive feeder lines are needed. Common applications include inductive and resistive loads such as motors, lighting and heating. Hevi-Duty general purpose transformers are manufactured to meet applicable industry standards, are listed in accordance with UL 506 and UL 1561 specifications and are classified as isolation transformers. The family of transformers includes: Distribution Transformers General Purpose Low Temperature Rise K-Factor Copper Wound Automation Transformers General Purpose Hazardous Location Buck-Boost Drive Isolation Industrial Control
