![]() ![]() ![]() A slimmer neck provides a better view of the weld pool and improved access to tight areas, for example. Neck lengths and bends: Gun necks are available in varying lengths and bend angles. When welders need to run at a higher voltage and deposit more filler metal into the weld, using a larger guard helps deflect the higher heat. In applications that require access to a corner joint, choosing a smaller guard increases maneuverability and provides more access. Heat shield: One of the most common features on self-shielded flux-cored welding guns is a hand guard or heat shield, which is available in different sizes. Choosing the right gun can help contractors tailor it to their specific needs and applications. Welding guns for self-shielded flux-cored applications are available in various configurations. Jolson Welding talks about the many benefits of using the Bernard Dura-Flux Self-Shielded Flux-Cored Gun.

Self-shielded flux-cored welding can be prone to slag inclusions if proper technique isn’t followed. The proper contact-tip-to-work distance depends on the application, but at least 1/2 inch is a good rule of thumb. In self-shielded flux-cored welding, the welder stays in the same spot, maintaining a consistent distance between the contact tip and the weld pool. As the rod shortens during welding, the welder gets physically closer to the weld, applying pressure to the stick electrode as it melts into the weld pool. When stick welding, the operator typically begins with the electrode (and therefore his or her body) farther from the weld. The different ergonomics of the self-shielded flux-cored gun compared to the stick electrode holder require approaching the weld from different angles and using different travel angles and pressure. Some training may be required for welders who are used to the stick process. Not using shielding gas also eliminates the need to set up tents or wind shields to protect the weld from the elements and the need to use specialty nozzles to control gas flow as is common with a gas-shielded flux-cored process. In addition to the greater productivity and deposition rates of the process, it also doesn’t require a shielding gas to protect the weld pool, eliminating the hassle and cost of buying and storing gas containers on the jobsite. ![]() Self-shielded flux-cored welding is becoming more common on jobsites for several reasons. Considering self-shielded flux-cored welding Gun options such as heat shields, configurable necks and adjustable cable lengths can help improve weld quality, efficiency and operator comfort in self-shielded flux-cored applications. Self-shielded flux-cored welding offers much greater travel speeds and deposition rates compared to stick welding, while also eliminating the frequent stopping and starting required to change out stick electrodes.įor contractors considering this conversion, there are some key factors to keep in mind to help choose the right self-shielded flux-cored welding gun for the job - and to use and maintain it properly. Self-Shielded Flux-Cored Welding: Choosing Your Gunįor structural applications, some contractors have made the switch from stick welding to self-shielded flux-cored welding to increase productivity and give themselves a competitive edge. Dura-Flux Self-Shielded Flux-Cored Gun with Replaceable Cable Liner.Dura-Flux Self-Shielded Flux-Cored Gun with Fixed Cable Liner.And when you’re ready to buy some tanks, they can also be run as MIG welders. They can be plugged into a normal electrical outlet and run without any gas tanks using a process called flux-cored arc welding (see opposite). We tested eight of the best new entry-level welders. Now welders are accessible to anyone, regardless of skill, and you don’t have to break your back or the bank to use one. While the usefulness of welders hasn’t changed a lot since then, the technology has. In his day welding required a complicated setup of machines and gas tanks that looked like they belonged on the set of a bad sci-fi movie. He started out running a welding shop, and later, during World War II, a school named Wicks Welding in Queens, New York. My great-grandfather was the first welder in my family. And when a neighbor needs a railing fixed, it’s my welder he wants me to use to fix it-usually for free. When I started my blacksmith business out of my grandparents’ garage, I used my welder to build a forge out of scrap metal. When I bought my first truck, a 20-year-old Tacoma with a rusty frame, my welder made it roadworthy. I can divide my life into two distinct segments: the time before I owned a welder, and every day since. ![]()
