By integrating a robust and functional design and safety features arc-tec tr series transformers tr-250, tr-400 and tr-500 are built for high performance welding jobs. The company`s dedicated `customer care cell` fully supports the after sales service of the equipment. Following are some advantageous features of the welding transformer which include:the equipment is ideal for light, medium and heavy-duty structural work, machine building and general fabrication work. It can also be used as a power source for gas tungsten arc welding [tig] for aluminium, magnesium and their alloys. An efficient cooling is ensured by the fan cooled design thereby increasing thermal capacity and life of the equipment. Electrical data includes: it is designed and constructed for connecting to 2 lines of ac 3 phase, 415 v, 50 hz input supply. The output current control is effected by a controlling handle in the front panel of the set.
