ESAB LHF 405 Pipemaster is a thyristor controlled welding rectifier designed for welding with coated electrodes and arc air gouging. It can be used with the following remote control devices: AT1, AT1 Coarse Fine. Some of its capabilities include:

• MMA welding: The device can be used for manual metal arc welding, also known as stick welding. This is a versatile welding process that can be used for a wide range of materials, including steel, stainless steel, and cast iron.
• Arc Air Gouging: The device can also be used for arc air gouging, a process that uses a high-temperature plasma arc to remove metal from a workpiece. This process can be used for a variety of purposes, such as preparing weld joints, removing old welds, and cutting metal.
