TUBESHEET WELD HEADS 424, 425, 430
Magnatech Tubesheet Heads are designed to make tube-to-tubesheet welds with precision and repeatability.
All models can be used for fusion welding. The models 424 and 425 provide for filler wire addition. An integral head-mounted feeder is standard.
Three models cover the size range of 10 to 140 mm (0.4 to 5.52”) OD. These weld heads improve productivity by increasing duty cycle, reducing repair rates and producing welds of consistent quality.
– Easy to operate
– Rugged Design
