A welder for plastics pipes and pipe fittings of the type for socket welding, comprising:
- a compact longitudinal supporting member (11), on which a sliding guide (12) is arranged,
- a carriage (13), which supports a first clamp (14) for locking a pipe fitting or a pipe and is arranged so as to slide on the sliding guide (12),
- a fixed post (16) on the longitudinal supporting member (11), which is arranged substantially at one end of the sliding guide (12) and on which a second locking clamp (17) for a pipe and/or pipe fitting is arranged,
- a movable block (18) for supporting a heating element (19) onto which the sleeve (54) for melting the pipe fittings or pipes is to be fixed. In the block (18) there are means (22) for kinematic connection to the carriage (13) and to the fixed post (16); an actuation handwheel (23) is associated with the kinematic connection means (22). The actuation handwheel (23), the means (20, 40) for closing the first locking clamp (14) and the second locking clamp (17), the means (47) for operating the heating element (19) can be arranged selectively on one of the two sides of the longitudinal supporting member (11), depending on the space available during use on already-installed pipes and/or pipe fittings. |
