How to Cut Welding
To cut welding, you can use a specific type of rod, such as 6011 or 6013, along with a welder set between 125-135 amps.
Begin by pushing the rod down onto the metal surface and keeping the tip flush.
This allows the arc to stay lit.
Cut a path by moving the stick along the metal, making sure to initiate the arc without creating a weld.
By following these steps, you can effectively cut through the metal using a lit arc.

Did You Know?
1. Welding is often associated with flames and heat, but did you know that lasers can also be used to cut through welding materials? Laser cutting is a precise and efficient method commonly employed in industrial applications.
2. In underwater welding, a process widely used in the construction and maintenance of offshore structures, welders work in highly pressurized environments that can be up to 6 times greater than normal atmospheric pressure.
3. The thickness of the material being welded can greatly influence the type of welding technique used. For instance, thicker materials often require the use of a technique called “submerged arc welding,” where a flux covers the arc to protect the weld from atmospheric contamination.
4. To ensure the integrity and quality of a weld, materials used in welding undergo careful inspection and testing. One such method is called “ultrasonic testing,” where high-frequency sound waves are used to detect any hidden or internal defects within the weld.
5. Welding has played a significant role in the aerospace industry for decades. In fact, during the construction of NASA’s Space Shuttle, over 2.5 million linear feet of welding was performed on the spacecraft’s aluminum alloy frame.
Introduction To Cutting Welding
Cutting welding is essential for every welder. It is important to know how to safely and efficiently cut welding metal. By using a welding rod (such as the 6011 or 6013 type) and a welder set at 125-135 amps, you can achieve accurate and clean cuts.
Some key points to keep in mind while cutting welding metal include:
- Use the correct welding rod type (6011 or 6013).
- Set the welder to the appropriate amperage (125-135 amps).
- Follow the proper cutting technique to ensure accurate cuts.
- Understand the principles of cutting welding to avoid unwanted welds.
In conclusion, mastering the skill of cutting welding is crucial for any welder as it can save both time and money in various welding projects.
Choosing The Right Rod Type
When it comes to cutting welding metal, selecting the right rod type is crucial. The two most common types for cutting are the 6011 and 6013 rods. The 6011 rod is known for its deep penetrating properties, making it an ideal choice for cutting thick metals. On the other hand, the 6013 rod is more versatile and can be used for both welding and cutting applications.
Setting Up The Welder (125-135)
Before you start cutting welding metal, it’s important to set up your welder properly. For cutting purposes, a welder set at 125-135 amps is generally recommended. Make sure you have a stable power source and the appropriate safety equipment, such as welding goggles and protective gloves, before proceeding. Adjust the amperage on your welder to the desired level and ensure that all connections are securely tightened.
- Set up your welder properly before cutting welding metal
- Use a welder set at 125-135 amps for cutting purposes
- Ensure you have a stable power source and safety equipment (welding goggles and protective gloves)
- Adjust the amperage on your welder to the desired level
- Securely tighten all connections
Proper Technique: Pushing The Rod Down And Keeping The Tip Flush
To achieve clean and precise cuts, it is essential to master the proper technique of pushing the rod down and keeping the tip flush. Start by positioning the rod at a 10-15 degree angle, pointing towards the direction you want to cut. Apply firm and steady pressure as you push the rod downward, allowing the tip to stay flush with the metal surface. This technique ensures that the arc stays lit and the cutting action is smooth and efficient.
Initiating The Arc For Cutting (Without Creating A Weld)
When initiating the arc for cutting, it is crucial to understand that you want to create a lit arc without creating a weld. Start by placing the rod near the edge of the metal you wish to cut and strike the metal with a short and quick motion. As the arc is initiated, slightly pull the rod back to maintain the appropriate distance between the rod and the metal surface. It is important not to linger in one spot for too long to prevent accidentally creating a weld.
Cutting The Metal: Creating A Lit Arc And Moving The Stick
Once the arc is established, it’s time to start cutting the metal. Maintain a steady pace as you move the stick along the desired cutting path, following the direction you want the metal to be removed. Remember to keep the tip of the rod flush with the metal surface and allow the lit arc to do the cutting work. Cutting welding metal requires patience and precision, so make sure to guide the stick smoothly and steadily to create a clean cut.
“Cutting welding metal can be a safe and efficient process if you follow the right techniques and use the appropriate equipment.”
By choosing the right rod type, setting up your welder correctly, and mastering the proper cutting technique, you can achieve accurate and clean cuts without creating unwanted welds. Remember to prioritize safety and always wear the required protective gear. With practice and experience, cutting welding metal will become a skill that you can rely on for various projects.
- Choose the right rod type
- Set up the welder correctly
- Master the proper cutting technique
Frequently Asked Questions
How do you cut through welding?
Cutting through welding can be achieved through a variety of methods. Thermally, oxyacetylene cutting or gouging, arc gouging, plasma cutting, and laser cutting can be employed. Oxyacetylene cutting utilizes a mixture of oxygen and acetylene to create a high-temperature flame that cuts through the welded material. Conversely, arc gouging utilizes an electric arc and an air jet to remove welds by melting and blowing away the metal. Plasma and laser cutting techniques use highly focused beams of plasma or laser light to melt and vaporize the weld, respectively.
On the other hand, mechanical means such as grinding, sawing, machining, and drilling can also be utilized to cut through welding. Grinding involves the use of abrasive wheels or discs to remove the weld layer by layer until the desired cutoff is achieved. Sawing utilizes a metal cutting saw blade to gradually cut through the weld, similar to cutting through wood or other materials. Machining employs specialized tools such as milling machines or lathes to remove the weld material, while drilling utilizes a drill bit to bore holes through the weld. With such diverse methods available, cutting through welding can be accomplished efficiently and effectively based on the specific requirements of the project.
How do you cut metal welding?
To cut metal using welding, start by selecting a high-quality cutting rod suitable for the task. Adjust the welder settings to ensure optimal cutting performance, typically around 125-135. Begin by initiating the arc, and unlike welding, the rod won’t create a weld. Instead, gradually push the rod into the steel and keep the tip flush with the other side. By maintaining a lit arc, you can effectively cut a path as you move the stick, resulting in precise metal cutting using welding techniques.
What is the best tool for cutting welds?
When it comes to cutting welds, one tool that stands out is the plasma cutter. This versatile tool uses a focused jet of ionized gas to slice through metal with precision and ease. Its high heat capability enables it to swiftly cut through even the toughest welds, making it a popular choice among professionals. Additionally, plasma cutters offer the advantage of minimal distortion and a smooth finish, making them an ideal tool for those seeking clean and accurate weld cuts.
How do you cut metal?
There are several ways to cut metal depending on the tools available to you. One common method is using a hacksaw, which is a hand tool with a fine-toothed blade that can slice through metal with ease. If you’re a DIYer, you can also try using a bench shear or tin snips from your toolbox to achieve precise cuts. Alternatively, power tools like a nibbler or bolt cutters can make quick work of cutting metal. Ultimately, the choice of tool will depend on the thickness and type of metal you’re working with.
