035 Dual Shield Flux Core Wire Settings: A Comprehensive Guide
Introduction
The 035 dual shield flux core wire is a popular choice among welders due to its versatility and excellent welding performance. However, to get the most out of this wire, it's essential to understand the optimal settings for different welding applications. In this article, we'll delve into the recommended settings for 035 dual shield flux core wire to help you achieve high-quality welds.
Machine Settings
Voltage
The ideal voltage range for 035 dual shield flux core wire is between 24-30 volts. This range provides a stable arc and prevents the wire from burning back too quickly. For thicker materials, you may need to increase the voltage to achieve a deeper penetration. However, be careful not to exceed 30 volts, as this can lead to porosity and lack of fusion.
Wire Feed Speed (WFS)
The wire feed speed (WFS) plays a crucial role in achieving the perfect weld. For 035 dual shield flux core wire, the recommended WFS is between 100-150 inches per minute (ipm). This range allows for a consistent arc and prevents the wire from overheating.
Shielding Gas
The shielding gas used with 035 dual shield flux core wire is typically a mixture of 75% Argon and 25% CO2. This gas mixture provides excellent shielding properties and helps to reduce porosity and oxidation.
Technique and Travel Speed
Travel Speed
The travel speed at which you move the welding gun affects the weld's quality and appearance. For 035 dual shield flux core wire, a travel speed of 6-8 inches per minute (ipm) is recommended. This speed allows for a smooth, consistent weld and prevents the wire from overheating.
Technique
To achieve a high-quality weld with 035 dual shield flux core wire, use a push angle of 10-15 degrees and a slight oscillation (about 1-2 inches) as you move along the joint. This technique helps to distribute the heat evenly and prevents lack of fusion.
Tips and Tricks
Wire Stickout
Maintain a wire stickout of 1/4 to 1/2 inch to ensure consistent arc ignition and prevent overheating.
Gun Angle
Keep the welding gun at a 10-15 degree angle to the workpiece to prevent wire burnback and achieve a smooth weld.
Interpass Temperature
Keep the interpass temperature below 500°F (260°C) to prevent overheating and reduce the risk of porosity.
Conclusion
By following the recommended settings and techniques outlined in this article, you'll be able to achieve high-quality welds with 035 dual shield flux core wire. Remember to adjust the settings according to your specific welding application and material thickness to ensure optimal results. Happy welding!
