How Does A Spool Gun Work?

It

Improves the Stability of Your Arcs

If you're having trouble steadying your arc, a spool gun could provide you with the stability you need. The gun's short feed distance means you don't have to feed too far before you hit the weld puddle. Such an advantage ensures you have a steady and consistent aluminum feed.

How does a MIG spool gun Work?

A spool gun is, in essence, a MIG gun with

the drive rolls for the wire mounted directly to the gun itself

. … If the wire becomes deformed, it won't feed through the gun anymore and begin tangling itself inside the cable or around the drive rolls.

Why do you need a spool gun for aluminum?

Successful welding with aluminum requires a stable arc. With its short feed distance, a spool gun provides

a steady, reliable feed of the soft aluminum wire

. A smooth feed to the weld is key to getting that smooth arc. … Even if it were, it would probably be harder to feed than solid aluminum.

Is a spool gun needed to weld aluminum?

Aluminum is a very soft metal, with a high melting point that requires high voltages. … The answer is yes and no, depending on the user's preference,

you do not necessarily need a spool gun to weld aluminum

.

When should you use a spool gun?

The Spool Gun is designed to connect to the HIT140/MMIG140 welders only. It is

used to feed wires that are difficult to feed through the standard MIG torch

. Most often this is used for aluminum wires, but any type of wire can be used on 4 inch spools.

What is the best spool gun?

Do you use AC or DC to MIG weld aluminum?

Q: When I gas tungsten arc weld (GTAW) aluminum, I

always use alternating current (AC)

, but when I gas metal arc weld (GMAW) aluminum, I always use direct current electrode positive (DCEP). … That's why you use DCEN to GTAW most materials. Additionally, in GTAW, DECEN maximizes weld penetration.

How thin can a spool gun Weld?

Spool guns can accommodate aluminum wire diameters from

. 023 to 1/16-inch

and allow the operator to use longer cables (15′-50′).

Can you weld aluminum with a MIG gun?

Aluminum is a tricky metal to weld with a MIG welder because it takes more heat than mild steel (Usually in the range of 21 to 24 volts). The minimum aluminum thickness you should attempt is roughly

14 ga. To 18 ga

. Any thinner than that and you'll need a TIG welder.

Can MIG weld aluminum?

Yes

, although aluminum can be tricky to MIG weld, it can be done. The process will require more heat than mild steel, which is the most common metal used in MIG welding jobs. Anything thinner than 18-gauge aluminum would require a TIG welder. Welding aluminum by using MIG techniques will be a unique experience.

Can gasless MIG weld aluminum?

Yes

, aluminum can be welded without gas in a vacuum chamber. However, welding aluminum gasless will expose the metal to the oxygen air circulating around your workspace and will make for a less secure weld.

Do you need a special welder for aluminum?

Metal inert gas (MIG) welding

can be successfully used to weld aluminum. … When choosing a shielding gas, 100 percent argon is best for MIG welding aluminum. The welder must choose a welding wire or rod that has an alloy as similar to that of the work pieces as possible to create a quality weld.

Do you push or pull aluminum spool gun?

Aluminum wire is

commonly fed with a spool gun or with a push-pull system

. … Using a spool gun eliminates the possibility of birdnesting because the wire only feeds a few inches. With a push-pull system, a motor in the gun pulls the wire through the liner, while a motor on the feeder acts as an assist motor.
