SMARTFab 125 Socket Welding Machine

The SmartFab 125 benchtop machine portable design allows it to be positioned on any flat surface for precise prefabrication, providing versatility in the shop as well as the field.

Advanced features of the SmartFab 125 provide more efficiency with innovative inserts that reduce ovality in pipe and fittings. The heater pivots to easily accommodate fittings situated on either side of the machine, which eliminates having to reposition the entire machine. Its four jaws adjust to any desired spacing and each jaw clamps individually to the desired pipe and fitting size.
