We have recently bought four new Lorch Handy TIG 180 welding machines. There are smaller, mobile welding machines, which are air cooled. The advantage is their low weight in relation to the welding power and easy operation. They are supplied with torches with the ability to control welding power and easy operation. They are supplied with the ability to control welding parameters and have flexible necks. The regulation of the torch improves operator convenience and parameters do not need to be manually adjusted on the welding machine plus the flexible neck provides better accessibility to less accessible places.
