![]() ![]() We’ll start at the top of the list as these are the simplest and work towards internal welder problems that could be resulting in no spark. ![]() There are a lot of reasons your welder may not be sparking, but fortunately, most of them are easy fixes. Polarity connections need to be examined.Welding drive roll tension needs adjustment.The work lead clamp is not properly connected.Metal connections areas are not clear or clean.These are the 5 most common reasons why your welder won’t spark: If your welder still won’t spark, there may be problems with the welder itself. If your welder is not sparking, you will first want to look at the welding conditions and environment for the easiest fixes. Why Won’t Your Welder Spark and What to Do 5.Look at Polarity Connection and Configuration.Welding Drive Roll Tension Needs Adjustment Why Won’t Your Welder Spark and What to Do.We will help you identify why your welder may not be sparking and the adjustments you can make to return your welder back into working (and sparking) condition. There are multiple reasons that could be responsible for your welder not sparking, both issues with the connection to the workpiece, or with the welder itself. Examine polarity (negative and positive wire configuration).Adjust wiring connection to and in welder.Make sure metal contact areas are clean.This is what to do when your welder won’t spark: Reason Nr. If these sparks don’t occur, you will not be able to produce clean or stable welds. In the process of arc welding, sparks are created when elements are burned at the electrode or weld puddle at very high temperatures to create your joined seam. This will ensure that issues are caught early on, allowing for adjustments to be made and preventing further defective output.Initiating a spark is a key indicator that an electrical arc has formed, and you can successfully join two pieces of metal together. The best way to catch defects is to incorporate quality testing throughout the welding process to confirm your weld meets the needed specifications. QA/QC plays a critical role in ensuring reliable welds are produced with minimal rework. Tackling Quality Assurance / Quality Control Other things to check are part fit up or damaged equipment (cables, clamps, etc.). ![]() Some of the most likely reasons your MIG process is resulting in poor quality welds is one or a combination of the following: It’s also worth noting that just because a weld doesn’t look “good” to the eye, doesn’t mean it’s bad! The following are the most common MIG welding problems:Ĭheck out our article dedicated to enhancing welding quality with more tips here. While many weld defects are usually easily spotted, some won’t show up until your part goes through the quality assurance process. During this process, an electric arc forms between the wire electrode and the metal-the emerging heat causes the metal to join and melt. The process uses a solid wire-or flux core wire vs a long “stick” electrode. GMAW welding, commonly known as MIG welding or wire welding, utilizes a semi-automated welding system. Read on to learn about common wire welding problems and tips for achieving high-quality welds. The team at Bancroft Engineering is here to empower you to take your GMAW / MIG / wire welding operation to the next level. ![]() Whether you have been welding for years or just getting started in your career, addressing and solving GMAW, MIG or wire welding defects can be extremely frustrating. ![]()
