In this episode of TIG Time we are welding on an engine mount that was brought to us for some repair. The mount is made of 4130 Chrome Moly and goes on a small, 2 seat aircraft called a Hummel Bird.

Aircraft engine mounts often develop small cracks that need repaired due to engine vibration. In this case, we show you how to prepare for welding tubular mounts by drilling a pressure hole as well as how to weld the crack. After the crack is welded, we will let the part cool down and re-weld the hole.

Welding with Cheater Lenses

Purchase cheater lenses through the Weld.com store

For aging welders, cheater lenses are one of those things you just need in order to get the best welds possible. Some people like to use reading glasses or other glasses, which is okay in a pinch, but it is always preferred to have a cheater lens installed in your helmet.

One of the major advantages of the cheater lens over normal reading glasses is that they will not slide down your face during welding. Every time you flip your hood, the lens will be in the perfect spot and remain there until you are through with you weld. For a cost of around $10, you can't go wrong investing in a cheater lens to help you see the weld.

Lincoln PowerMIG 210 MP Review (Part 3): Stick Welding

In our final episode on the review of the Lincoln Electric PowerMIG 210 MP, we look at the stick welding functions of the machine. Yes, that's right... Stick Welding! We don't claim to be the experts in the stick welding process on TIG Time, which is why this is such a good test for the machine. If we can easily set and use the machine to perform quality stick welds, they must have done something right in the making of this machine.

So far, the front panel on this machine has been so easy to use, someone who has never welded in their life could probably set the machine; and that is for all processes we have tested. Lets check out the stick functions and see if they are just as easy as TIG and MIG or if there was a disconnect somewhere.

Welder Showdown: Expensive vs. Cheap Inverters

Since the introduction of inverter technology, TIG welders have been becoming more and more affordable to the home hobbyist. We classify TIG welders into two different categories, Utility and Industrial. In this episode, we look at one machine from each category that we like and show some of the differences and how they perform.

First, we look at the time tested (Industrial) Lincoln Electric V205T. This is one of our favorite inverters and is built to last. It has been through side load impact testing, exposure testing, load tests and more and exceeds all expectations for industrial use.

The second machine we tested was the Everlast PowerTIG 125 (Utility). This is a 110V only machine that is built for the weekend warrior. This welder is not as durable as the Industrial Lincoln, however the welds it produces are very similar. The performance we got out of this $900 welder is remarkably similar to the performance we got out of the $4000 Lincoln.

The Lincoln PowerMIG 210 MP is Lincoln Electric's entry level multi process welder. It combines MIG, TIG and Stick welders all in one machine. Last week we looked at the TIG functions of the machine and considered them to be just "Okay". In this week's episode we will test out the MIG welding functions. As this is a TIG welding show, we usually do not get into the MIG process (and don't claim to be experts on it), but this machine's interface is so easy to use, let's see how it makes us look!
