How to Stick Weld Farm Equipment: A Comprehensive DIY Guide

Stick welding, also known as Shielded Metal Arc Welding (SMAW), is a versatile and cost-effective welding process that is widely used for on-field, garage, or farm equipment repairs. This comprehensive guide will provide you with advanced, hands-on details and technical specifications on how to stick weld farm equipment as a DIY user.

Understanding Stick Welding

Stick welding is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. The flux coating on the electrode serves multiple purposes:

  1. Arc Stabilization: The flux coating helps to stabilize the arc, making it easier to maintain a consistent welding arc.
  2. Shielding: The flux coating melts and forms a gaseous shield around the weld pool, protecting the molten metal from atmospheric contamination.
  3. Slag Formation: The flux coating also forms a slag layer on top of the weld, which helps to protect the weld from oxidation and provides a smooth, uniform finish.

Stick welding is particularly useful for farm equipment repairs due to its ability to burn through light layers of dirt, rust, or contamination on the metal surface. This makes it an ideal choice for on-site repairs where the equipment may have been exposed to the elements.

Choosing the Right Equipment

To stick weld farm equipment, you will need the following equipment:

  1. Stick Welder: For farm equipment repairs, a 160 Amps dual voltage synergic stick welding machine, such as the ARCCAPTAIN ARC160, is recommended. This welder offers two welding modes, MMA (Manual Metal Arc) and Lift TIG, making it suitable for both professionals and beginners.
  2. Safety Gear: Proper safety gear is essential when stick welding. This includes a welding helmet with a suitable lens shade, welding gloves, a flame-resistant jacket or coveralls, and steel-toed boots.
  3. Electrodes: The electrode diameter for farm equipment repairs typically ranges from 3/32″ to 5/32″. The specific electrode diameter you choose will depend on the thickness of the metal you are welding.

Selecting the Right Electrode Diameter

The diameter of the electrodes used in stick welding can range from 1/16″ and 5/64″ up to 3/16″ and higher. For farm equipment repairs, the following electrode diameters are commonly used:

Electrode Diameter Metal Thickness
3/32″ (2.4 mm) 1/8″ to 3/16″
1/8″ (3.2 mm) 3/16″ to 1/4″
5/32″ (4.0 mm) 1/4″ to 3/8″

As a general rule of thumb, select an electrode diameter that is one size smaller than the thickness of the base metal you are welding. This will help ensure proper penetration and a strong, high-quality weld.

Preparing the Metal

Before you begin welding, it is essential to prepare the metal surface to ensure a strong, high-quality weld. Use a chipping hammer and wire brush to remove any dirt, rust, or contamination from the weld area. This will help the weld penetrate the base metal and create a stronger, more durable bond.

Setting Up the Welder

When setting up the welder, you will need to adjust the amperage and polarity based on the thickness and type of the metal you are welding. For thin metals, use DCEN (Direct Current Electrode Negative or DC-), which offers lower penetration. For medium-thickness metals, you can use DCEP (Direct Current Electrode Positive or DC+), which offers higher penetration.

To set the appropriate amperage, refer to the electrode manufacturer’s recommendations or use the following guidelines:

  • 3/32″ (2.4 mm) electrode: 60-100 Amps
  • 1/8″ (3.2 mm) electrode: 90-130 Amps
  • 5/32″ (4.0 mm) electrode: 120-160 Amps

Striking the Arc

To strike the arc, follow these steps:

  1. Hold the electrode about 1/8″ to 1/4″ away from the base metal.
  2. Touch the electrode to the base metal to create a small spark.
  3. Quickly pull the electrode back, maintaining a consistent arc length.
  4. Maintain a consistent travel speed to prevent overheating and warping of the metal.

Practicing Stick Welding Techniques

Stick welding requires practice to master the techniques and balance travel speed, work angle, travel angle, and electrode manipulation. Be patient and keep practicing until you achieve high-quality welds. Some key techniques to focus on include:

  1. Maintaining a Consistent Arc Length: Keep the arc length between 1/8″ and 1/4″ to ensure proper penetration and a stable arc.
  2. Controlling the Welding Puddle: Observe the size and shape of the welding puddle, and adjust your travel speed and electrode angle accordingly.
  3. Manipulating the Electrode: Experiment with different electrode manipulation techniques, such as the whipping or weaving motion, to achieve the desired weld profile.
  4. Monitoring Weld Appearance: Inspect the weld appearance and adjust your technique if you notice any issues, such as excessive spatter, porosity, or uneven bead formation.

By mastering these techniques, you will be able to produce high-quality, durable welds on a variety of farm equipment components.


Stick welding is a versatile and cost-effective welding process that is well-suited for farm equipment repairs. By understanding the fundamentals of stick welding, choosing the right equipment, and practicing the proper techniques, you can become a skilled DIY stick welder and tackle a wide range of farm equipment maintenance and repair tasks.

Remember to always prioritize safety, follow the manufacturer’s recommendations, and continuously practice to improve your welding skills. With the right approach, you can become a confident and capable stick welder, ready to tackle any farm equipment repair challenge that comes your way.
