Quality Assurance (QA) is a set of defined processes for systematic monitoring and evaluation to assure product quality.
Quality Control (QC) is the process of confirming that the product meets the specifications. It includes the checking and testing of manufacturing procedures as well as the final products. The results from these tests are compared with a set of defined acceptance criteria. By carrying out QC testing during manufacturing, defects can be identified in a timely manner, allowing for the product flaw to be rectified and if required, adjustments to be made in the manufacturing process to prevent further defective output.
In welding, QA/QC plays a vital role in ensuring sound and reliable welds are produced and in minimizing rework. (more…)

ArcReach® technology is an investment that results in a lot of time saved during welding operations. With most welding equipment the operator needs to walk back and forth to adjust output voltage – sometimes over hundreds of feet – multiple times during a job. This results in hundreds of wasted hours and thousands of lost dollars over the course of a large project.
ArcReach technology enables welders to adjust the voltage settings right at the point of welding
ArcReach technology enables welders to adjust the voltage settings right at the point of welding instead of walking all the way to the power source and back. Even worse, if the voltage settings are “just good enough”, the operator might not bother making the trip, resulting in lower quality welds. (more…)
