Why PFS Makes Modifications To The ARC 656 Stud Welder

While the ARC-656 three phase stud welding power supply has numerous advantages, among them a compact size that makes them more portable and a minutely adjustable front panel digital display, a number of complications still exist with the factory model. Never content to merely make do, Production Fastening Systems collaborated with engineers and on-site welders to produce a modified version that resolved the problems in question.

Factory:

The factory model ARC-656 is equipped with a single handle, which makes relocating the power supply cumbersome.

PFS Modified Advantage:

The ARC-656M, PFS’s refined model, provides dual handles that make moving the equipment more manageable for two people or even a single welder.

Factory:

A continuous duty fan means that the internal workings of the factory model ARC-656 are vulnerable to the copious quantities of dirt and debris on jobsites. Furthermore, energy efficiency is compromised by a continuous duty fan.

PFS Modified Advantage:

The ARC-656M innovatively relies on an on-demand cooling fan. Activated only when the equipment needs to be cooled, the highly efficient modification also reduces the amount of debris infiltrating the unit.

Factory:

The factory model power supply is equipped with a 25 Ft. extension weld and control cable, which means that the equipment must be moved frequently to reach weld studs that cover a larger area.

PFS Modified Advantage:

PFS’s model is furnished with a 50 Ft. extension weld and control cable, allowing welders to cover a greater distance without the continuous interruption of moving the unit.

Additional features:

    • The modified ARC-656M comes with a hard wired power cable secured by Kellum grips that can be quickly disconnected and moved via male and female twist lock power connectors.

 

  • The ARC-656M improves upon the factory model’s arc gun with a dampener that ensures a smooth weld fillet and reduced splatter and a bi-pod foot that ensures perpendicularity for each stud
