Welding cameras are not something that every Weekend Warrior is going to have for the garage, but they do play a large part in industry and welding education. There are a lot of welding cameras out on the market and this one is the only that we have come across that has zoom and focus, making it easy to move from application to application.

Welding Project: Cast Aluminum Intake Manifold Repair

Cast Aluminum, like any cast material can be very difficult to weld. It is important to follow specific procedures before attemptimg to weld a cast metal piece to insure you get a good solid weld. Many welders will preheat the entire part to a suitable temperature before they begin welding, and this is often a good idea. However, on this project, our intake manifold has two four barrel carburetors on it and we don't want to risk damaging (or igniting) them with preheating.

You will see in this video how we go about preheating without risking the integrity of the carburetors, as well as learn some other ways of preparing the cracks to be welded and what materials and techniques to use to weld the manifold.

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.

Welding Heavy Wall Aluminum with the Everlast 325EXT

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.

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.
