Clamp-on weld heads expand orbital GTAW system

The Lincoln Electric Co. has introduced HELIX® C series orbital GTAW clamp-on weld heads. They allow operators to weld large-diameter pipes and tubes with no upper limit, as well as smaller-diameter pipes and tubes. They are designed for use with the manufacturer’s APEX® 2100 orbital welding system and HELIX WF20S and WF20B orbital wire feeders.

The C450 weld head is designed for pipes and tubes with ODs from 1.315 to 4.5 in., while the C663 is suitable for ODs from 1.9 to 6.63 in. They feature a water-cooled motor housing and torch to help ensure extended performance and high cycle ratings in heavy-duty, high-heat applications, the company states.
