  • Why did Mike decide to test different flux core wires?

    -Mike decided to test different flux core wires after noticing that the Hynade flux wire that came with his new welder produced less spatter and had a shinier appearance compared to other wires he had used before.

  • What焊s the Hynade 140 amp flux core welder that Mike purchased?

    -The Hynade 140 amp flux core welder is notable for its dual voltage capability and auto-setting feature for wire speed based on voltage, which Mike found to weld smoothly and be user-friendly.

  • Which flux core wires did Mike test in the video?

    -Mike tested Lincoln, Vulcan, Forney, Yes Welder, and Hynade flux core wires in the video.

  • What is the significance of the wire's appearance and packaging?

    -The appearance and packaging of the wire can indicate its quality; shinier wires might suggest better manufacturing, and vacuum-sealed pouches prevent moisture from affecting the wire's performance.

  • What is the importance of travel speed when welding with flux core wire?

    -When welding with flux core wire, a slower travel speed is necessary because the wire is hollow. This allows for proper weld puddle observation and ensures adequate wire is added for a strong weld.

  • Why is it important to change the leads on a flux only welder?

    -Changing the leads on a flux only welder is crucial because these welders are internally wired as DC electrode negative, which is different from MIG welders for solid wire that are wired as DC electrode positive. Incorrect lead setup can result in poor welding results.

  • What should the stick out length be when welding with flux core wire?

    -The stick out length, or the amount of wire extending from the contact tip, should be longer than when welding with solid wire, typically ranging from a quarter to three-quarters of an inch, with Mike preferring about a half-inch stick out.

  • What does the saying 'if it's got slag you drag' mean in the context of flux core welding?

    -The saying 'if it's got slag you drag' means that when welding with flux core wire, one should always pull the wire (rather than pushing it) to avoid incorporating flux inside the weld, which can cause porosity.

  • How did Mike evaluate the performance of the different flux core wires?

    -Mike evaluated the performance of the flux core wires by observing the welding process, the amount of spatter produced, the ease of cleaning off slag, and the quality of the final weld after cleaning.

  • What was Mike's final ranking of the flux core wires based on his tests?

    -Mike ranked the wires from worst to best as follows: Vulcan, Lincoln, Forney, Yes Welder, and Hynade, with Forney, Yes Welder, and Hynade being the top three that performed very similarly and were superior to the others.

Keywords

💡Flux Core Wire

Flux core wire is a type of welding wire that contains a flux in the core, which provides its own shielding gas. In the video, different brands of flux core wire are tested to compare their performance in terms of spatter and weld quality.

💡Spatter

Spatter refers to the small droplets of molten material that are ejected during the welding process and do not form part of the weld. The video discusses how different flux core wires produce varying amounts of spatter, impacting the cleanliness of the weld.

💡Hynade 140 Amp Welder

The Hynade 140 Amp Welder is a flux core welding machine tested in the video. It features dual voltage capabilities and an auto-setting function for wire speed and voltage, making it user-friendly and effective for producing smooth welds.

💡Weld Bead

A weld bead is the deposit of filler metal from a single welding pass. The video examines the appearance and quality of weld beads created with different flux core wires, noting differences in spatter, smoothness, and consistency.

💡DC Electrode Negative

DC Electrode Negative (DCEN) refers to the polarity setup where the electrode (mig gun) is negative and the workpiece clamp is positive. This is the configuration used for flux core welding in the video, which affects the weld characteristics and quality.

💡Forney Wire

Forney Wire is one of the flux core wire brands tested in the video. It is highlighted for its smooth performance, clean welds, and minimal spatter, making it one of the preferred choices by the end of the video.

💡Stick Out

Stick out refers to the length of the wire extending from the welding gun's nozzle to the workpiece. The video advises using a longer stick out for flux core welding compared to solid wire welding, as this helps manage the weld pool and spatter.

💡Dual Voltage

Dual voltage capability allows a welding machine to operate on two different voltage inputs, typically 120V and 240V. The Hynade 140 Amp Welder's dual voltage feature is discussed in the video, providing flexibility and power for various welding tasks.

💡Wire Speed

Wire speed is the rate at which welding wire is fed into the weld pool. The video explains how the Hynade welder auto-sets wire speed based on the selected voltage, contributing to the ease of achieving consistent, high-quality welds.

💡Slag

Slag is the byproduct of the flux that forms on the surface of the weld bead, protecting it as it cools. The video emphasizes the importance of removing slag after welding to evaluate the weld quality and discusses the ease of slag removal with different wire brands.
