In this episode we take another look at the Everlast 325EXT TIG welder. In the first episode, "How to Weld Thin Wall Stainless Steel with the Everlast 325EXT" we tested the low end of the machine on DC. In this episode, we put this machine through the ringer and see how it performs at its high end on some super heavy Aluminum bar stock.

To test the machine, we performed 3 welds:
Bead on Plate (3/8" Aluminum) - To see how the machines cleaning action worked.
3/8" Lap Joint - We did this part cold to see how the machine performed on a cold part.
1.5" Bar Stock to 3/8" Plate Fillet - We did this to really test the high end of the machines output.

3/8" Aluminum Bead on Plate:
We performed this weld cold to really test how the machine would do welding a part that had no heat treatment whatsoever. We set the machine at a maximum of 250 amps.

In this video we take a look at the new Everlast 325EXT TIG welder. In part 1, of this 2 part series, we put some of this welders features to the test:

- Low End DC Welding (under 10 amps)
- Pulsing features
- Ease of Setup

Testing the low end amperage performance:
To test the machines low end amperage performance in DC mode, we decided to weld on a real world application. Rather than run some beands on plate and welding some scrap together, we thought we would show you how to weld with and without filler material on some products we make and sell in the store. In the first part of this video you will see how we weld stainless steel trail cups to be used for welding exotic materials that need increased gas coverage, like Titanium.

Choosing a Good Foot Control for TIG Welding

Like many other accessories in TIG welding, it can be confusing when try to choose a good foot pedal for your welder. It is easy to get confused, because you would think that foot pedals are interchangeable from machine to machine, but that is absolutely NOT the case. There are even some cases where you will need a seperate foot control if you buy a new machine from the same manufacturer.

In this video we compared four different models that are commonly paired with the machines we use on the show, both imports and domestic machines. There are many different aspects of a foot pedal that you should look at before deciding to spend the money, espescially because TIG is such a finesse process.

Here are some of the things we compared for you:

Using a Wire Feeder for TIG Welding: Part 2

When most people think "TIG welding", they normally think of a manual, slow process that requires two hands and lots of coordination and practice. One of the major upsides of MIG welding is how easy it is to learn the basics and get started welding, something that is NOT so easy to do with GTAW.

In this video we take a second look at the CK Worldwide WF-5 wire feeder for TIG welding. What this machine does is automates the wire feeding process of TIG welding. This allows the operator to focus on other things like puddle control, travel speed, heat input and a host of other things that need to be monitored while TIG welding.

TIG welding Aluminum is a difficult material to weld (See this video for a beginners video on how to weld Aluminum). There are so many things to worry about that don't come into play with most other materials, such as hot short cracking, increased heat absorption and many other factors. This is one reason why some welders get nervous when it comes to certifying in Aluminum. If this video, we go over one of the more difficult certifications, the cluster.

Here are some things to remember when welding a cluster (with any material):
