Connect the red ballast wire to both of the red wires leading from the lamp sockets. Already signed up? Improve productivity with technologies that enhance efficiency and save you money. Metko took some time out from a recent training effort to offer the following advice. Sign in / Create Account. If you are looking for a selfshielded wire that offers excellent impact properties even at -40C you should definitely take a closer look at our OA S-71-T8, it offers outstanding welding properties and due to the rutile-basic slag system the arc runs smooth with practicaly no spatters ! Greg Metko, a welding engineer with Miller Electric Mfg. A: Yes. It displays voltage while welding and for five seconds after you stop welding. Most Remove any wire connectors from the black and white circuit wires coming from the electrical box to which the fluorescent light is mounted. Fortunately, some inverters popular for construction work, like Miller's XMT 350 VS, can compensate for voltage spikes and dips. A: Because they operate in a very narrow voltage range. When welding products of relatively small thickness, two-dimensional heat dissipation is present. Copyright 2020 Hearst Communications, Inc. Ballast incompatibility can cause premature light failure or damaged equipment. All that may be necessary to remove the housing is to manually squeeze the sides of the housing together to release the housing from the tabs. Easier to use products through auto-settings and better visibility. If you are unsure whether your T8 ballast will work with your fixture, sockets or the supply voltage, consult an electrician. For an all-position fillet weld, its operating range is just 19 to 22 volts. Please meet the best wire that the market has to offer for outside welding without protective gas ! To activate your FREE subscription today, simply select which newsletter(s) you would like to receive and complete the form below. Make sure your weld cables are sized properly and that the cable, clamp and all connections are in good condition. Q: Why are self-shielded T-8 wires so difficult? If you find voltage, check that you have turned off the correct breaker. Use 8-32 screws to mount the new ballast to the fixture. He lives in Oakland, Calif., working as an electrician and carpenter. Replace the ballast housing and any lens, if present. Q: What happens to the weld if the right voltage isn't used? If any of the bulbs are faulty, dispose of them according to your municipal or county regulations on hazardous waste disposal. These screws may have nuts attached or the screws may be threaded into tapped holes. Extremely low voltage causes "gun buck" where the wire dives through the molten weld pool and stubs on the plate. At least one newsletter must be selected. Fluorescent tubes contain toxic chemicals. Optimize your operation through advanced welding processes, training and weld data monitoring. While popular and/or necessary for structural welds, these wires are notoriously difficult to use. A ballast is an electronic device that regulates the current required to illuminate a fluorescent tube. T8 ballasts are designed to work together with T8 bulbs, which are commonly found in 4- or 8-foot lengths. Self-shielded flux cored wires meeting AWS E71T-8 requirements comprise much of the wire used for structural steel in buildings, bridges, civil construction and infrastructure applications. *Please select at least one e-Newsletter. A: There are lots of contributing factors, but the one I see the most during training is improper electrode stick-out. You may need to remove the ballast housing to access the mounting holes. Strip away 1/2 inch from the black and white wires on the ballast, if necessary. Thank you for subscribing to our eNewsletters. The contact tip to work distance (stick-out plus arc length) will be about 1 inch. I am not knocking ESAB Coreshield 8. I will admit I run a lot of Lincoln stick and wire because it what I am used to having around. Regardless of whether you are wiring a new fixture or retrofitting an older, existing fixture, always make sure there is no voltage present and maintain a safe working environment. Sign in / Create Account. Remove the housing of the ballast. Point the wire into the leading edge of weld puddle and angle the gun toward the direction of travel by 5 or 10 degrees. Or if you don't have a Miller account, create one today. Turn off the breaker that supplies power to the circuit you're working on.

He is one of the experts dedicated to "training the trainers." The sockets themselves may need to be replaced. Strip 1/2 inch of insulation from these wires' ends, as needed.
