The advantages of the 120 GE impulse generator are quickly explained: small, compact, robust and equipped with a 3-meter plug cable - so the impulse generator can also be used for large-format packaging.
Provided, of course, that you connect a suitable welding tong. And here there are several options you can choose from.
Form:
D-Tongs (standard): The heating band supports and the pliers handles are arranged in a T-shape. The tong opening is approx. 20 mm. These tongs weld the film material directly at the edge of the bag or max. 25 mm away from it.
SFZ-Tongs: Here too, the heating band carrier and pliers handles are arranged in a T-shape. However, these pliers can be opened a little further (approx. 25 mm) thanks to the extended pliers clamp and can place the weld seam up to approx. 100 mm from the edge of the bag.
DS-Tongs: Here the heating band supports are arranged as a kind of extension of the pliers handles. This arrangement allows the heating band supports to "grip" the foil material like scissors.
Weld length:
The weld seam lengths of the welding tongs can be between 150 and 600 mm, depending on the tong shape.
By the way: the welding tongs also have a 3 meter connection cable to the pulse generator, so that the welding unit can normally move up to 6 meters from the socket in the room. If that is not enough, another 3 meters can be added using an extension cable.
