Abstract:
A welding appliance for cross-welding liquid-filled plastic tubing has a tube receptacle (15), a tube squeezing arrangement with a movable pressure clamp (3) and a welding arrangement with an electrode (2). In order to prevent leakage of radio-frequency perturbing radiation in the area of the tube receptacle (15), a shielding device (21) is movably arranged in the area of the tube receptacle (15). In addition, a covering device (23) for the electrode (2) is arranged in the area of the tube receptacle (15) of the welding appliance. The welding appliance may also be designed as a table-type appliance, with several welding appliances movably arranged next to each other in the direction of the tubing.
