What Is Arc Welding, and How Does a 120 Volts Stick Welder Function?
Arc welding is a welding process that uses an electric arc to melt and join metals. It typically involves a filler material and requires a welding machine to create an electric current between the welding rod and the workpieces.
According to the American Welding Society, arc welding is defined as “a group of welding processes that generate heat through an electric arc between a bare or covered electrode and the workpiece.” This definition comes from a reputable organization recognized for standards in welding.
Arc welding operates on the principle that an electric arc generates intense heat, which melts both the filler metal and the base material, allowing them to fuse. The welder controls the arc length, heat input, and travel speed to ensure a strong joint. Various techniques, such as shielded metal arc welding (SMAW) and gas metal arc welding (GMAW), exist within this category.
The National Center for Construction Education and Research states that the average operating voltage for stick welders is typically around 220 to 240 volts. However, a 120 volts stick welder operates at a lower voltage, making it suitable for light-duty applications such as home repairs or automotive work.
Stick welding accounts for a significant portion of the welding industry, with millions of units used worldwide. Market reports predict steady growth in the welding equipment sector due to increased construction activities.
The impacts of arc welding include safety hazards such as exposure to high heat and fumes, affecting worker health. Proper ventilation, protective gear, and training can mitigate these risks. Additionally, welding can produce waste and emissions, prompting environmental concerns.
In practice, welding safety programs, equipment maintenance, and environmental regulations can improve outcomes. Organizations like the Occupational Safety and Health Administration (OSHA) recommend adherence to safety standards and regular training to reduce accidents.
In conclusion, employing safety measures and proper equipment can ensure successful and responsible use of arc welding technologies.

Implementing these safety measures creates a safer welding environment. Each measure addresses specific risks associated with welding.
-
Personal Protective Equipment (PPE):
Using personal protective equipment is critical for the welder’s safety. PPE includes gloves, helmets, goggles, and flame-resistant clothing. The American National Standards Institute (ANSI) recommends using appropriate PPE to reduce exposure to welding fumes, sparks, and UV radiation. For example, a welding helmet equipped with a filter lens can protect the eyes from harmful light and flying debris, preventing conditions like arc eye. Studies show that 60% of welding injuries result from inadequate protective gear. -
Fire Safety:
Fire safety is crucial when welding. Sparks generated during welding can ignite nearby flammable materials. To mitigate this risk, keep a fire extinguisher nearby and clear the workspace of combustibles. The National Fire Protection Association (NFPA) states that improper storage of flammable materials contributes to nearly 76% of welding-related fires. Establishing a ‘fire watch’ during operations in elevated risk environments is recommended, particularly in closed or confined spaces. -
Ventilation:
Proper ventilation is vital to minimize exposure to harmful welding fumes and gases. Fumes can cause respiratory issues, and poor ventilation increases inhalation risks. The Occupational Safety and Health Administration (OSHA) recommends using local exhaust ventilation systems to remove contaminants effectively. Inadequate ventilation increases the likelihood of health problems, making this a priority in welding areas. -
Electrical Safety:
Working with electricity always carries risks. Stick welders require proper grounding to prevent electric shock. It is essential to check cables for damage and ensure all connections are secure before use. The National Electrical Code (NEC) emphasizes the importance of using Ground Fault Circuit Interrupters (GFCIs) in wet environments to mitigate shock hazards. Ensuring electrical safety can significantly reduce accidents during welding tasks. -
Workspace Organization:
Maintaining an organized workspace enhances safety during welding. Clutter can lead to accidents. Ensuring tools, materials, and equipment are stored properly decreases the chances of tripping hazards and allows for greater focus on the task. The American Welding Society (AWS) highlights that 25% of welding accidents stem from poor workspace management. -
Protective Barriers:
Using protective barriers can prevent unwanted exposure to radiant heat and sparks. Barriers shield nearby workers and equipment from welding processes. The AWS recommends implementing protective shields in high-traffic areas during welding operations. Utilizing screens or curtains can enhance safety, especially in shared workspaces. -
Equipment Inspection:
Regular equipment inspection is essential for maintaining safety standards. Faulty welding machines can pose dangers such as electric shock or equipment failure. The AWS suggests conducting routine checks on cables, connectors, and protective casings before each use. Proper maintenance not only prolongs equipment life but also ensures safe operation. -
Emergency Procedures:
Establishing clear emergency procedures is crucial for effective response during incidents. Providing accessible first-aid kits and conducting training sessions prepares workers for potential accidents.

- Clean the workpiece surface
- Control travel speed
- Optimize arc length
- Monitor heat input
- Use proper safety gear
Understanding these techniques will enhance results and ensure safety.
-
Maintain Proper Electrode Angle: Maintaining a proper angle when holding the electrode is essential. A 15 to 30-degree angle from vertical promotes a stable arc and reduces the risk of defects. An incorrect angle can lead to insufficient penetration or poor bead formation.
-
Select the Right Electrode Type: Choosing the appropriate electrode is critical for achieving quality welds. Common types include E6011 and E6013. E6011 is suitable for dirty or rusty materials, while E6013 is ideal for clean metals and provides a smooth finish.
-
Adjust Welding Current Settings: Adjusting the amperage settings on your welder is vital. An amperage that is too high can cause excessive spatter, while too low an amperage may prevent proper fusion. Aim for the manufacturer’s recommendations based on the electrode size.
-
Clean the Workpiece Surface: A clean surface ensures better adhesion and quality of the weld. Remove rust, paint, and grease from the material before welding. This prevents contamination, which can lead to defects in the weld.
-
Control Travel Speed: Travel speed influences the heat input and fusion of the weld. A consistent and moderate travel speed will allow the weld to penetrate sufficiently without burning through the material. Practicing on scrap metal can help you find the ideal speed.
-
Optimize Arc Length: The arc length can greatly affect the quality of the weld. A shorter arc length yields a tighter arc with better penetration, while a longer arc may lead to undercuts and inconsistent weld beads. Maintain an arc length of about 1/16 to 1/8 inch.
-
Monitor Heat Input: Excessive heat can cause warping or burn-through. Conversely, insufficient heat results in weak welds. Understanding the relationship between welding speed, current, and heat is essential. Adjust these variables as necessary during the process.
-
Use Proper Safety Gear: Using safety gear protects against hazards associated with welding. A welding helmet, gloves, and flame-resistant clothing minimize injury risk. Always prioritize safety to maintain focus on technique and quality.
By applying these techniques systematically, you can achieve high-quality welds with your 120 Volts stick welder while ensuring a safe working environment.
