As a welding expert with years of experience in the field, I can provide you with a comprehensive understanding of the relationship between an arc welder and a stick welder.

Arc welding is a broad term that encompasses various welding processes that use an electric arc to produce heat for melting metals at the welding point. This category includes several types of welding techniques, such as Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), and Submerged Arc Welding (SAW), among others.

Shielded Metal Arc Welding (SMAW), also referred to as Manual Metal Arc Welding (MMA or MMAW), is one of the most common types of arc welding. This process is known for its versatility and is often used in various industries due to its ease of use and the ability to weld in different positions. The term "stick welding" is a colloquial term for SMAW, and it is derived from the fact that the electrode used in this process is a consumable rod that resembles a stick.

In SMAW, the electrode is coated with a special type of flux that serves multiple purposes. The flux acts as a shield to protect the molten weld pool from atmospheric contamination, such as oxygen and nitrogen, which can cause defects in the weld. It also provides a source of slag, which is a non-metallic material that forms on the surface of the weld and protects it from impurities. Additionally, the flux coating on the electrode contains compounds that release gases when heated, which helps to stabilize the arc and improve the overall welding process.

The process of SMAW involves striking an arc between the consumable electrode and the base metal, which generates the necessary heat to melt both the electrode and the base metal, forming a weld pool. As the electrode is consumed, it is continuously fed into the weld pool, and the welder manipulates the electrode to control the size and shape of the weld bead.

It is important to distinguish between an arc welder as a general term and a stick welder as a specific type of arc welding process. While all stick welders are arc welders, not all arc welders are stick welders. For instance, Gas Metal Arc Welding (GMAW), also known as Metal Inert Gas (MIG) welding, uses a continuous wire feed instead of a consumable stick electrode and relies on an externally supplied shielding gas to protect the weld pool.

Gas Tungsten Arc Welding (GTAW), commonly known as Tungsten Inert Gas (TIG) welding, is another type of arc welding that uses a non-consumable tungsten electrode to produce the arc. GTAW is known for producing high-quality welds with greater control over the weld pool, but it is generally slower and more labor-intensive than SMAW.

In summary, while the terms "arc welder" and "stick welder" are often used interchangeably in casual conversation, they refer to different concepts within the welding industry. An arc welder is a general term for any welding process that uses an electric arc, while a stick welder specifically refers to the SMAW process, which uses a consumable electrode covered with flux.
