AC/DC Stick Welder: Reviewing the Top 8 Units

Do you need that AC/DC stick welder? Well, yes, of course. More tools equal better, right? We must have ALL the tools.

However, a few things might allow you to live without the latest and greatest in the stick welding world.

For instance, if you are a woodworker that never touches metal? Yeah, you can skip this purchase.

But then, your workbench has metal legs and shelf supports. If they break, you can’t work with wood. Maybe you should stick (ha – see what I did there?) around anyway.

Stick Welding is Shielded Metal Arc Welding (SMAW). Widely used, it employs an electrode (the “stick”) and current to create welded joints in metals. It is simple, easy to learn, versatile, and useful.

The most common use is in the maintenance trades and construction to weld iron and steel. Many home mechanics also use it for repairs around the house, fixing that old trailer frame, and making steampunk regalia.

AC/DC – Whosee- Whatsee

Even people that have worked with SMAW for years don’t understand how it works — they know that an AC/DC stick welder gets the job done.

We’ll be introducing some standard terms in this section that will appear in bold type. You will see these terms used, and no one ever seems to define them, so we will do that first.

Stick welders work either with alternating current (AC) or direct current (DC). Current creates an electric arc (this is where the name comes from) between the stick (electrode) and the metals you are fusing. The area where the arc is formed is called the weld pool.

The electrode provides filler metal for the joint and bead. The joint is the seam where the two metals join. The bead is the material left behind by the electrode that forms the bond.

While MIG, TIG, and Arc welding are in the “stick welding” basket, there are differences.

The four basic types of welding

MIG Welding is Gas Metal Arc Welding (GMAW). They use a continuously feeding electrode through the handle or “gun.”

MIG welding fuses metal using the melting electrode, rather than melting the metal you are fusing. A gas bubble protects the weld from the air and other contaminants. Both the gas and the electrode wire are consumable.

TIG Welding, Gas Tungsten Arc Welding (GTAW), uses a tungsten electrode, which is non-consumable.

TIG Welding melts and fuses the metals. Separate rods can create filler or fuse two different metals. The gas also protects from contaminants and requires tank refills.

Stick Welding, as mentioned earlier, is Shielded Metal Arc Welding (SMAW). The single electrode (stick) is heated and melts. The process creates intense heat that also melts the workpiece, making the seam.

This process uses flux-coated electrodes to produce a shield around the joint to keep contaminants out. The rods melt, so you’ll want to keep a steady supply of them on-hand.

Arc Welding, also known as Flux Core Welding, uses a continuous-feed wire (like MIG welding). The wire has a flux core that generates the protective gas shield around the weld.

In dual-shielded welding, a secondary gas is externally added for more protection against contaminants.

DC Stick Welding Explained

In DC welding, the electrons flow in one direction, delivering constant polarity, which may be positive or negative.

Although most electric welding machines allow the user to switch from AC to DC manually, knowing a bit about each will help you decide which is better for your garage.

Many welders use DC polarity for most welding jobs. There are always advantages and disadvantages. One of the benefits is that DC polarity can weld delicate items such as remote controls and cell phone batteries.

With the stable arc and smoother output come greater versatility.

Advantages of DC Stick Welding

We’ve already discussed a couple of advantages of DC stick welding. There are many more:

  • More stable and easier to learn
  • Easier starts (better-looking beads)
  • Works well even during inclement weather (wind and rain)
  • Produces less splatter/slag
  • Equipment is relatively inexpensive and cost-effective
  • Rod changes are quick and easy to shift to different metals
  • The ground clamp can attach farther from the welding area
  • Better on thinner metals than TIG

The most significant advantage of DC stick welding is the ease of learning. With a small amount of practice, a novice welder can learn to lay a sweet bead. That opens the door to doing new projects or fixing that old cast iron patio set.

Disadvantages of DC Stick Welding

There is always the obligatory list of disadvantages with anything, and that includes DC stick welding.

  • An internal transformer is required, making a DC welder more costly
  • Don’t produce enough high-intensity heat to weld aluminum
  • No fix for arc blow

Although a considerably shorter list, if you plan to make an aluminum table, they may be a deal-killer.

AC Stick Welding Explained

With AC welding, the electron flow constantly switches directions, which results in polarity changes at a rate of 120 times per second.

When the polarity shifts, this results in a period of zero amperage output. With an inexperienced welder, this can cause an uneven bead.

There are special electrodes for AC stick welding that keep them from extinguishing during the zero-output phase. Welders will still have more flutter and fluctuation than they experience using DC polarity.

Advantages of AC Stick Welding

There are some applications where AC stick welding offers extreme advantages over DC. Some of them include:

  • Can use in higher voltage applications
  • Fixes arc blow problems experienced with DC
  • Works better when welding magnetized parts
  • Supports welding at a higher temperature
  • Offers deep penetration of plate metals

Even though AC is often a secondary choice for welding, it does offer some unique advantages over DC welding. It may be the only power supply available, so learning a bit about it may save your project.

Disadvantages of AC Stick Welding

This list is pretty small.

  • Creates more splatter
  • Bead is not as smooth due to changing polarity and zero-output phases
  • More challenging to learn and master
  • Not as reliable as DC welding

Short and sweet. If you are buying a welder and finance are short, don’t be afraid to opt for the AC-only machine.

It will serve you well for most home-use applications. You will have a more significant learning curve due to the difficulty of using AC over DC.
