If you experience wire stubbing, start the arc about 1/4 inch closer, then move it back once it is established. The exact combination of wires will depend on the type of ballast that was present in the fixture. A: Poor weld cables are a common culprit of excess voltage drop. Miller's Trailblazer® Series and PipePro™ engine drives are specifically designed to overcome this problem. Restore power to the circuit and check the operation of the new ballast by switching on the light. Perhaps more than any other tubular electrode, these wires demand special considerations—in both technique and equipment—for obtaining good results.
These screws may have nuts attached or the screws may be threaded into tapped holes. Note that analog meters aren't very accurate compared to a digital display, and any readout back at the power source won't be accurate because long cable lengths common in field welding cause voltage drop. T8 ballasts are designed to work together with T8 bulbs, which are commonly found in 4- or 8-foot lengths. A: Yes. If the holes differ, drill and tap new holes that coincide with the position of the holes on the new ballast. The contact tip to work distance (stick-out plus arc length) will be about 1 inch. Or if you don't have a Miller account, create one today. Lighting Retrofit and Relighting: A Guide to Energy Efficient Lighting; James R. Benya, Donna J. Leban , Willard L. Warren. Remove any bulbs within the fixture. Greg Metko, a welding engineer with Miller Electric Mfg. Examine the new light fixture: A new T8 fluorescent lamp should already have the sockets and ballasts wired in the proper configuration. Clip or jog the wire so that you start with the proper stick-out of 3/4 inch. Easier to use products through auto-settings and better visibility. Remove the lens, if present. Mount the new fixture to the ceiling or wall. A: Because they operate in a very narrow voltage range.
Q: Do welders need to do anything special during arc starts? Or if you don't have a Miller account, create one today. Do not discard the housing. The entered e-mail addresses do not match. Extremely low voltage causes "gun buck" where the wire dives through the molten weld pool and stubs on the plate. Miller respects your privacy concerns. Advice for Welding With Self-Shielded Flux Cored Wires 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.

With an electric welder, primary power fluctuations can affect weld voltage. Check the type of the original ballast. Take care not to break the bulbs. Sign in / Create Account. While popular and/or necessary for structural welds, these wires are notoriously difficult to use. Make sure the fixture is safely mounted, either to the ceiling joists, wall studs or with a code-approved electrical box designed to support a fluorescent light. A helper may be necessary to flip breakers for you while you test for voltage.
Also remove any wire connectors that may be present between the old ballast's wires and the wires leading to the light sockets. Other styles of housing may require the removal of one or more small machine screws or hex screws.
For good results when welding with AWS E71T-8 flux cored wires, maintain a proper stick-out (3/4 inch) and use the proper gun angle (5 to 10 degrees toward the direction of travel). Fluorescent tubes contain toxic chemicals. Greg Metko, welding engineer with Miller Electric Mfg.
Floyd Elliff of Local 263 (on right) tests the weld coupon of April Finkbonner from Local 86. Some T-8 wires simply won't run well if you don't use a drag technique. Fortunately, some inverters popular for construction work, like Miller's XMT® 350 VS, can compensate for voltage spikes and dips. Sign in / Create Account. *Please select at least one e-Newsletter. If you make a weld outside of that range, the odds of the weld failing inspection are pretty good. A: Yes.
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. He is one of the experts dedicated to "training the trainers." Co., discusses best practices for welding self-shielded flux cored wires.
In this video you’ll see, amongst other things, our order picking system and badge registration using a very clever registration model, Certilas ® guarantees faultless delivery and full traceability of your ordered goods. Turn off the breaker that supplies power to the circuit you're working on. How to Wire a T8 Ballast. We’d like to take you on a tour through our company. © Copyright 2020 Hearst Communications, Inc. Ballast incompatibility can cause premature light failure or damaged equipment. Even if procedures don't demand it, Miller always recommends a CV welder for wire welding. There should also be a red and blue set of wires on the ballast. A ballast is an electronic device that regulates the current required to illuminate a fluorescent tube. The cooling time t8/5 is calculated according to the following … St. Clair holds a bachelor's degree in public policy from Emory & Henry College and a master's degree in city planning from University of North Carolina-Chapel Hill, where he specialized in food system planning. Most … It displays voltage while welding and for five seconds after you stop welding. Use the appropriate size driver bit and a cordless driver, or use the appropriate hand tool, to remove any screws holding the housing in place. Check the position of the mounting screw holes of the new ballast against the position of the holes on the old ballast.
Often, the ballast housing is a piece of metal held in place with small tabs. Q: How do welders know if they're using the right voltage? Too much stick-out will cause the amperage to drop outside of the proper range and the weld may have insufficient penetration. Replace the ballast housing.
A: Yes.
With some engine drives, drawing on generator power while welding (such as using a grinder) may also affect arc voltage. Although gas metal arc welding (GMAW) with a solid mild steel wire is popular, easy-to-use, and effective for many applications, it does have limitations and drawbacks. Strip 1/2 inch of insulation from these wires' ends, as needed. Connect the black and white wires from the house circuit cable to the black and white wires leading from the ballast, using wire connectors. Point the wire into the leading edge of weld puddle and angle the gun toward the direction of travel by 5 or 10 degrees. If any of the bulbs are faulty, dispose of them according to your municipal or county regulations on hazardous waste disposal. If you are unsure about the compatibility of the fixture and your T8 ballast, consult a lighting technician. Take a 5/64-in.
The sockets themselves may need to be replaced. This type of machine lets the operator set voltage and wire feed speed/amperage, which makes it easy to "dial-in" optimum welding parameters. Optimize your operation through advanced welding processes, training and weld data monitoring. A: The weld will have little to no spatter, no porosity and a slightly convex appearance. It is also critical to keep the wire directed in the molten slag pool, otherwise wire will dive into the plate, stub and create a cold spot. When using a flux cored welding gun, this is the distance from the end of the contact tip to the arc. Q: What happens to the weld if the right voltage isn't used?

When starting, hold the contact tip about the same distance away from the work as when you're welding (which is 3/4 of an inch), pull the gun trigger, wait a second or two for the arc to establish and the weld puddle to form, and then drag the gun forward.
Q: What is the most common cause of voltage variations? Co., discusses best practices for welding self-shielded flux cored wires. 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. Read our privacy policy for more information. If you are looking for a selfshielded wire that offers excellent impact properties even at -40°C 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 !
Also, long stick-outs may pre-heat the wire too long, which may change the composition of the wire. I am not knocking ESAB Coreshield 8.
Wiring a direct replacement T8 ballast can be relatively straightforward, although retrofitting another type of fixture, such as T12, may be more challenging. 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. Co., has spent thousands of hours training Ironworkers how to successfully weld with self-shielded flux cored wires. Restore power to the circuit and check that the light is operating properly at the switch. You may need to remove the ballast housing to access the mounting holes. With a self-shielded T-8 wire, the operator needs to maintain a stick-out of 3/4 inch. Already signed up? I think wire brands are like anything else in the welding world. If your wire feeder has a "soft start" or "run-in control," you can use those features to improve arc starts.<-->. Q: Should you use a specific type of power source for good voltage control? Use 8-32 screws to mount the new ballast to the fixture. A: Excess arc voltage causes porosity, while lack of voltage causes a convex, "humped" or "ropey" bead and potentially insufficient penetration. Strip away 1/2 inch from the black and white wires on the ballast, if necessary. Remove the housing of the ballast. Take care to not obscure the entrance hole for the 120-V supply wires with the ballast. A good way to ensure proper voltage is to use a portable wire feeder with a digital voltage display, such as the SuitCase® X-TREME™ 12VS.
