Product Questions and Answers

Can the PipeWorx be used to weld plate?

The Welding Processes in the PipeWorx were Developed and Optimized for all-position, Pipe Welding Applications using Filler Metals and Shielding Gases that are commonly used by customers that manufacture welded spool assemblies in a shop environment. During our development and testing, we have found that the PipeWorx Welding processes are very robust. As a result, it is highly likely that users will be able to find settings that produce High Quality Welds on Plate Applications.

Can the PipeWorx be used on 208-volt power input?

The PipeWorx was not designed to operate on 208-volt. We typically (but not always) receive the request when a demo is planned at a distributor location. The power source will operate on a minimum 208-volt input. A degradation of weld performance will occur below 208-volt input and above 500 ipm wire feed speed.

Can the PipeWorx Run on Single Phase Power?

The PipeWorx 400 is designed to run only on 3 phase power. If 3 phase power is not available, it is possible to use a phase converter to power the PipeWorx 400.

Can the PipeWorx be used to weld aluminum?

The PipeWorx System was not designed to weld aluminum because this was a negligible requirement in a pipe shop.

Does the suitcase feeder operate on the PipeWorx System?

There is not a suitcase feeder available for the PipeWorx 400 System. The PipeWorx System was not designed for field applications. Pipe shops require higher amperages for roll welding, less environmental protection and operate on single voltages, while field applications require more portability (less amperage), environmental protection and need to operate on various voltages (auto line). The PipeWorx 350 FieldPro system was designed to bring the benefits of the PipeWorx into the Field.

Can we provide a complete system with ground cables, gas hoses and regulators – like AMS?

The weld package 951381 has been ordered by most customers. This package comes with a dual feeder. We have completed a dual feeder accessory package 300568, which includes a work cable and clamp, two gas hoses and two regulators. This is shown on the spec sheet. If the customer has a bulk gas system, two hoses and regulators are not required.
