Subsequently, armed with this understanding, you can then identify the welder that suits you most effectively.


Comprehensive Overview of Welding Processes

In the realm of welding, various processes exist, with MIG, TIG, and Stick standing out as the most common. However, it’s crucial to recognize that there’s no universal approach suitable for all applications; instead, each method comes with distinct advantages and limitations tailored to specific tasks.

MIG/Gas Metal Arc Welding (GMAW)

MIG welders employ a wire welding electrode, automatically fed at a consistent pre-selected speed from a spool. The resulting arc, formed by the electrical current between the base metal and the wire, melts the wire and fuses it with the base material. This yields a high-strength weld with an appealing finish, often requiring minimal post-weld cleaning. MIG welding is user-friendly, applicable to both thin and thick metals, and excels in producing clean welds on steel, aluminum, and stainless steel.

A variation of MIG, flux-cored arc welding (FCAW), utilizes a wire-feed process but eliminates the need for shielding gas in self-shielded FCAW. Instead, flux-cored wire shields the arc from contamination, proving advantageous in outdoor, windy, or challenging conditions. FCAW is a preferred method in construction due to its speed and portability, showcasing its efficiency in various scenarios.

TIG/Gas Tungsten Arc Welding (GTAW)

TIG welding involves a non-consumable tungsten electrode to create welds. Shielding gas, usually argon, and filler metal (though not always necessary) protect the weld area from atmospheric contamination. A constant-current power supply generates energy conducted across the arc through a plasma column of highly ionized gas and metal vapors.

TIG welding finds its niche in joining thin sections of alloy steel, stainless steel, and nonferrous metals like aluminum, magnesium, and copper alloys. Offering superior control over the arc, TIG delivers strong, high-quality welds. Despite its complexity and slower pace compared to other processes, TIG welding remains an excellent choice for intricate projects requiring meticulous precision.

Stick/Shielded Metal Arc Welding (SMAW)

Stick welding has been a staple in home-shop work for years. This process involves an electric current flowing from the gap between the metal and the arc-welding electrode. While effective for welding most alloys or joints, Stick welding’s versatility extends to indoor and outdoor use, making it suitable for work in drafty conditions. Cost-effective and capable of creating robust bonds on rusty or dirty metals, Stick welding is a practical choice.

However, Stick welding does have its limitations, including the ability to handle metals no thinner than 18 gauge, frequent rod changes, notable spatter emission, and the necessity for post-weld cleaning. It demands a steeper learning curve, particularly in striking and maintaining an arc. Available in AC, DC, or AC/DC, Stick welders are economical and find favor among farmers, hobbyists, and those engaged in home maintenance tasks, particularly when dealing with thicker metals of 1/16 inch or greater.

Frequently Asked Questions

  1. What amperage is required for welding?
    The measure of electricity flow, or amperage, in welding is synonymous with heat. A general rule is that for every 0.001 inch of material thickness, 1 amp of output is needed. For instance, welding a base material that is 0.125-inch thick requires 125 amps, while welding material that is 0.250-inch thick demands 250 amps.
  2. What does duty cycle mean in welding?
    The duty cycle in welding refers to the duration within a 10-minute period that a power source can operate continuously before overheating. For instance, a machine with a 40% duty cycle can operate for four minutes and then must rest for six minutes. Duty cycle ratings are specified in a machine’s product specifications and are typically based on the amps and welding process in use. Lower outputs result in increased duty cycle, and vice versa. For example, the Multimatic 220 AC/DC has a 60% duty cycle at 105 amps for MIG or flux-cored welding and a 20% duty cycle at 200 amps for the same processes.
  3. What duty cycle is suitable for a welder?
    The appropriate duty cycle rating for a power source depends on the type of work performed most frequently. In a shop or garage setting, a machine with a lower duty cycle can usually handle most jobs, as operators often use lower amperages and pause more frequently, allowing the machine to cool down. In a light manufacturing or fabrication production environment where higher amperages are used more frequently, a machine with a 60% duty cycle is typically employed.
  4. Which welder is best for outdoor welding?
    For outdoor welding, processes like stick or self-shielded flux-cored welding are preferred, as they don’t require a shielding gas. Versatile multiprocess equipment, such as the Multimatic 215, is recommended for outdoor jobs, providing the flexibility to tackle various tasks with either stick or flux-cored welding. Stick welding is suitable for quick jobs or repairs on dirty metal, while wire-feed flux-cored welding is more efficient for larger projects. An engine-driven welder like the Bobcat™ 265, with its 9,500-watt output, is suitable for power generation needs.
  5. What is the ideal welder for shop welding?
    When choosing a welder for a shop, consider amperage needs and available power. Multiprocess welders, such as the Multimatic 220 AC/DC, are advantageous for shop work as they allow versatility in using different processes like stick, TIG, MIG, and flux-cored welding without the need for multiple machines. However, if MIG welding is the primary task, the Millermatic 211 is a reliable choice, capable of welding up to 3/16-inch material at 120V and up to 3/8-inch material at 240V.
