Can You Welding The Aluminum With Hobart 140

Welding aluminum with hobart handler 140

Hobart 140 was not a really suitable welder for welding aluminum especially with the one that have more than 1/8″ even you using it with the spool gun, some other experienced welder who does not have the right kits for aluminum will weld it ​​without using spool gun as they said it will give a great results.

I would not recommend it, but if you really have no other option and have 120v power supply, an mvp machine, mig or tig, might be worth looking into, you can watch the video below to learn about Hobart 140 spool gun installation.

The 140 will only have enough power to weld up to 1/8″ if its clean and Argon is what you use with aluminum.But still, it is possible for you to weld aluminum with this unit.You can try to buy a spool and if it doesn’t work you will still have the bottle and the wire for your new welder/spool gun combo.

However, it will take your patients and some practice.Just keep at it till you get all settings fine tuned, even some of the contras with it, the Hobart Handler 140 are still the MIG welder who are not want to go with the 220 unit welder. – You can read the hobart 140 review by clicking the link below…

Working with aluminum was a unique challenges, and it is important for you to clean the aluminum before welding, this will remove the oxide layer and use only a stainless steel wire brush for cleaning the aluminum.

Aluminum Feeding

Compared to welding with other steel materials, the most common problem with the aluminum was the feedability, it’s incomplete fusion at the start of a weld, and crater or termination cracking at the ends of the weld.The best feeding of wire for aluminum is done with a spool gun. If you can’t use a spool gun, use the shortest gun possible and keep the gun as straight as possible.Use Argon only for shielding the gas and only use a push gun technique when welding aluminum.


Feedability is probably the most common problem experienced when moving from MIG welding of steel to MIG welding of aluminum.Feedability is a far more significant issue with aluminum than steel.This is primarily due to the difference between the materials’ mechanical properties.

Aluminum is softer, more susceptible to being deformed or shaved during the feeding operation, and consequently requires far more attention when selecting and setting up the feeding system for your MIG welding.

The Best Way To Welding Aluminum

The best method for welding aluminum is by using the tungsten inert gas welding.TIG welders are fairly expensive and it’s hard to justify buying even the lowest quality units unless you are making money with your welding.

When the tungsten gets touches the weld pool or the filler, the arc becomes unstable and the weld quality goes way down.It maybe will happens to you.And the solution for you to fixing this is to remove the tungsten, lay it on a flat surface with the contaminated part hanging over the edge, hit the contaminated part of the tungsten (it will snap right off), reinstall the tungsten, change the polarity to DCEP (direct current electrode positive), strike an arc on some scrap metal to re-ball the tungsten, switch back to AC high, and you’re ready to weld again. – source: http://artsautomotive.com/

If you want to perform “best-quality” aluminum welding every day you will need a good welder machine.And as i mentioning before, the best way to welding aluminum is using the TIG welding, and below is my recommended for best TIG welder machine.

Square Wave TIG 200 TIG Welder

The Square Wave® TIG 200 is a portable TIG and stick welding machine that lets hobbyists, makers, small fabricators and craftsmen explore their creativity.It is designed to help expand your welding expertise.As your skills and confidence grow, you can take advantage of the Square Wave TIG 200’s additional functionality.No matter your skill level, you won’t be disappointed.In the video below you will see Jim opens the box on a brand new Lincoln Electric Square Wave TIG 200. 

He walks through the machine’s features and setup. Then he connects the gas line, power cord, foot pedal and assembles the TIG torch. Next, Jim runs some beads on both aluminum and stainless steel giving handy welding tips and his overall review on the machine’s performance.

2 MIG Welding Tips

1. MIG Welding Tip – This is probably one of the most important mig welding tips ever!Ever heard someone light up with a mig gun and it sounds like a drive-by shooting?You know what’s wrong? Bad ground!That’s right a bad ground.It is such a simple fix but I hear that sound all the time.

People have trashed machines and bought new ones for this reason alone and all the while, all that was wrong was a bad ground. Why? Have you paid close attention to ground clamps recently? They suck! I mean they really suck! It used to be that ground clamps were made from copper. Now they are plated steel with a tiny piece of copper on the jaws.

Guess what? The old ones are better.

You could say that about a lot of things right? But here’s a secret: you can still buy the old ones. It is no secret that copper is the best conductor.That’s why copper ground clamps are better. Especially ones that have a strong ass spring.

2. MIG Welding Tip – The second most important of Mig welding tips is  the “stickout”.Many of welders misunderstood with this Stickout, what it really means is the distance from the mig welding tip (also called contact tip) to the arc.Not the distance from the nozzle to the arc! too long a stickout will soften the arc and make the weld pile up.

A longer stickout can be a good thing on really thin sheet metal like body panels and for high amperage spray transfer a longer stickout is preffered.But if you want a good crisp arc using short circuit mig on thicker metal, keep the stickout less than 1/2 inch.

    For over 50 years, plasma cutters have been the preferred method of cutting metal. Since the 70's, they have gained industry wide acceptance because they offer several advantages over other cutting methods. Take a look at the reasons why plasma cutters are so popular….
