The a.c. brushless generators-welders series denominated HM1 guarantees unlimited operation without extraordinay mantenance. In fact, its particular circuitation allows to have full maximum power both as a single-phase generator and as a welder. The distribution along the sides of the unit of the output sockets makes its use quite manageable and guarantees the most usual versions of the generator panel. The a.c. welder is governed by a selector switch which controls the two functions (generator or welder) and by a commutator which regulates the welding current with seven positions on two scales (one scale for 130 amp version). All this inside a robust alluminum structure with reduced dimensions and contained weight.
The HM1 series has been engineered to satisfy the most common and simple end-user needs where the use of a single-phase generator with good performances is complemented by an excellent a.c. welder which permits the melting of the most common diameters for rutile-type electrodes.
