How to Set Up Welding Machine for Smaw
To set up a welding machine for SMAW (Shielded Metal Arc Welding), you need to consider the type of electrode you are using and adjust the amperage accordingly.
TechShop Menlo Park offers two types of electrodes, namely 6011 and 6013.
The 6011 electrode is recommended for deep penetration with a thin layer of slag, while the 6013 electrode is recommended for better weld appearance and easily removable thick slag.
For vertical down welding, use the 6013 electrode, and for vertical up welding, use the 6011 electrode.
Beginners should practice with the 6013 electrode on thick steel.
Use the electrode diameter chart provided on the Hobart Welders website to determine the proper diameter, and set the amperage within the recommended range indicated in the article.

Did You Know?
1. In ancient times, welding was performed by using two pieces of metal heated in a forge and then hammered together. The pressure created through the hammering process would forge a bond between the metals, achieving a basic form of welding.
2. The first successful arc welding method was invented by an English chemist named Sir Humphry Davy in the early 19th century. He unknowingly laid the foundation for future welding techniques when he discovered that electric current could produce an arc between two carbon electrodes, thus producing a heat source for welding.
3. The term “Smaw” in “How to Set Up Welding Machine for Smaw” stands for Shielded Metal Arc Welding. This welding process, also known as stick welding, involves using a consumable electrode covered in flux to create the arc which melts the base metal and forms the weld.
4. One of the essential steps in setting up a welding machine for Smaw is choosing the correct electrode diameter. The diameter of the electrode determines the maximum amperage that can be used during the welding process. A general rule of thumb is that for every 1/32 inch of electrode diameter, you should use approximately 1 amp of welding current.
5. It’s important to note that Smaw welding produces slag as a byproduct. Slag is a layer of impurities that forms on the surface of the weld and needs to be cleaned away after the welding process. Removing the slag ensures a clean weld and enhances the integrity of the finished weld joint.
Choosing The Right Electrode: 6011 Vs 6013
When it comes to setting up a welding machine for Shielded Metal Arc Welding (SMAW), also known as stick welding, one of the most crucial decisions is choosing the right electrode.
At TechShop Menlo Park, two types of electrodes are offered:
- 6011 (fast freeze)
- 6013 (fast fill)
The 6011 electrode is recommended for deep penetration with a thin layer of slag. It is suitable for applications where strong and high-quality welds are required.
On the other hand, the 6013 electrode is ideal for better weld appearance and easily removable thick slag. It provides smooth and clean welds, making it suitable for projects where aesthetics matter.
Welding Techniques For Different Electrodes
Once you have chosen the appropriate electrode for your project, it is essential to understand the welding techniques associated with each type.
- For welding out of position, different techniques are employed based on the electrode chosen.
For vertical down welding, where the weld progresses from top to bottom, the 6013 electrode is recommended. It allows for better control and stability while ensuring a strong weld.
On the other hand, for vertical up welding, where the weld progresses from bottom to top, the 6011 electrode is preferred. Its strong penetration capabilities make it suitable for welding in this position.
- 6013 electrode: recommended for vertical down welding
- 6011 electrode: preferred for vertical up welding
Welding Out Of Position: Vertical Down Vs Vertical Up
Welding out of position entails specific techniques to achieve high-quality welds, particularly in vertical down and vertical up positions.
In vertical down welding, gravity plays a key role by assisting in the welding process, resulting in faster and cleaner welds. To prevent issues like undercutting and excessive heat input, it is important to maintain a steady travel speed and control the electrode angle.
On the other hand, vertical up welding requires meticulous attention to detail. The welder must carefully manage the travel speed to ensure proper fusion and heat input. Additionally, controlling the electrode angle and maintaining a consistent arc length is crucial in preventing slag inclusion and ensuring the weld’s integrity.
To summarize, when welding out of position:
- Vertical down welding: Maintain steady travel speed, control electrode angle to prevent undercutting and excessive heat input.
- Vertical up welding: Manage travel speed, control electrode angle, and maintain consistent arc length to prevent slag inclusion and maintain weld integrity.
Beginner’s Tip: Practicing With The 6013 Electrode
For beginners in stick welding, it is recommended to start practicing with the 6013 electrode on thick steel. This electrode is highly versatile and forgiving, making it an excellent choice for beginners to understand the basics of stick welding. Its ease of use and forgiving nature allow beginners to focus on proper technique and maintaining a stable arc.
It is important to note that mastering welding techniques takes time and practice. By starting with the 6013 electrode, beginners can gain confidence and gradually progress to more challenging electrodes and welding positions.
Determining The Proper Electrode Diameter
Choosing the correct electrode diameter is vital for achieving optimal weld results. Welding electrode diameter is determined based on the thickness of the material being welded. A chart provided by Hobart Welders can help in determining the proper electrode diameter for a specific project.
By matching the electrode diameter to the material thickness, welders can ensure proper penetration and weld quality. Using an electrode that is too small may result in incomplete fusion, while using an electrode that is too large can lead to excessive heat input and distortion.
- Using the correct electrode diameter is crucial for achieving optimal weld results.
- Welding electrode diameter depends on the material thickness.
- Hobart Welders provides a chart to determine the appropriate electrode diameter.
- Matching the electrode diameter to the material thickness ensures proper penetration and weld quality.
- Using a smaller electrode may result in incomplete fusion.
- Using a larger electrode can cause excessive heat input and distortion.

Setting The Amperage On The Welding Machine
The amperage on the welding machine needs to be properly set according to the proper amperage range indicated on the chart provided in this article. The amperage setting is crucial for achieving the desired weld quality and avoiding potential weld defects.
Higher amperage settings offer deeper penetration, while lower settings provide better control and finesse. It is important to refer to the chart and the specific requirements of the project to determine the appropriate amperage range. Adjustments can be made based on the weld pool size, joint configuration, and welding position.
Navigating the complexities of setting up a welding machine for SMAW may seem daunting at first, but with the right knowledge and practice, it becomes a manageable task. By choosing the right electrode, employing proper welding techniques, understanding the different welding positions, practicing with beginner-friendly electrodes, determining the proper electrode diameter, and setting the amperage correctly, beginners can embark on their stick welding journey with confidence and produce high-quality welds.
Frequently Asked Questions
What is the first step in setting up the SMAW equipment?
When setting up the SMAW equipment, the first step is to ensure that the power switch on the machine is set to OFF and the safety switch on the wall is also set to OFF. This provides a safe starting point to plug in the machine.
