The new professional torch with double water-cooling circuit.
New torch BZ551with double water-cooling system guarantees an additional cooling of the consumables, drastically reducing their wear. The double cooling system guarantees a higher flow of the liquid, less spurt adhesion and a higher durability of the consumables. The ergonomic and lightweight handgrip allows excellent weight balancing and easy manoeuvrability without straining too much the user’s hand. A special protective edge on the button prevents accidental ignition.
Available with 3 different cables measurements: 3 – 4 – 5 metres.
RECOMMENDED USE
BZ 551 torches excel in the MIG pulsate applications. Ideal for medium heavy carpentry, for steel wires up to 1.6 mm and for aluminium and stainless-steel wires up to 1.0 mm in diameter.

The MIG/MAG welding process is a continuous process in which the weld pool protection is guaranteed by a cover gas flowing from the torch onto the part to be welded. Being a continuous process ensures high productivity of the process itself, and at the same time the presence of gas allows for operation without scorching (both these features increase the affordability of the electrode welding process).
MIG/MAG WELDING APPLICATIONS
MIG/MAG welding is used when high productivity and a high degree of flexibility are required. With this technology, it is possible to weld both austenitic and ferritic steels, light metal alloys (Al and Mg), copper alloys, nickel alloys and titanium alloys. Since the weld pool protection is guaranteed by a gas flow, this procedure is only recommended in workshops, as even moderate wind can cause dispersion of the gas flow with a resulting reduction in the quality of the welded joint. It is possible in some cases to work outside, making protective domes around the area to be welded.
