The worklead connects from the power supply (internal connection on the main power board), the other end should have a welding clamp that connects to the workpiece (the metal that you are cutting). If you need help with the internal connection you can refer to the 1100 operators manual, if you do not have the manual you can download it from the documents library on the Plasma, waterjet and laser cutting systems from Hypertherm website or contact technical service at Hypertherm. technical.service@hypertherm.com or 1 800 643 9878 ..
