This week, we weld stainless tubing. After talking about scratch start tig welding a few weeks ago, I thought I’d talk about how to weld stainless tubing…a 6g stanless tube test using the same crude scratch start tig setup. It’s a Lincoln 225 AC buzz box with a diy rectifier hooked up to a...
What is the arc force setting on new inverter welders? What is Dig? What is arc control on an older Miller syncrowave 250? Guess what? These differently named control knobs are the same thing. No matter what the name, it is a setting that allows you to adjust the arc to a soft smooth...
This weekly video is about Tig Welding 4140 Steel to 1045 Steel. The customer supplied a drawing to modify 20 snap ring pliers and weld some jaws on the end that were machined out of 4140. Inconel 82 tig rod was used because I have had a lot of success with inconel 82 in...
This is Part 2 of building a boom arm for a mig welder. A millermatic 250 mig welder to be exact. The aim is to remove the wire feeder components from the welder and install them in a separate wire feeder cabinet that will hang on the end of the boom. This is a...
This weekly video is about a simple scratch start tig setup along with a diy foot switch. The rectifier seems to put out a very wavy DC current. I kinda like it. It’s like high speed pulse. What kind of stuff have you welded with a simple scratch start rig? ( As always, feel...
This weekly video is about how AC frequency settings on a tig inverter can affect the weld. Here is the bottom line: If you need to get all heat you can into the part, a lower frequency like 50hz works. For build up beads and stacked beads on castings where you are replacing metal...
This is Part 2 and it is welding the top half of this heavy duty aluminum fixture. I am not exactly sure what it does or why it was designed out of aluminum, but it obviously holds some large round part that needs to raise up and down and spin. Sometimes it’s good to...
I got a thick aluminum job in the shop and also got a new Lincoln Powermig 350mp with push pull gun. Pretty freaking awesome. I wish I had the time to really tweak the setting before tackling this job with a new setup like this but this part needs to get done asap. Deadlines.....
This video shows several tig welding tips and techniques along with a heavy dose of Tig Fingers. The Tig Finger really helps for every situation I showed it being used in this video. Its a quick way to prop near the weld without going to a lot of trouble. Check out what customers are...
This weekly welding video is about building a boom arm for a mig welding wire feeder. The reason for the boom arm is so that I can have a 35 foot radius where I can mig weld without ever moving the mig welder or the gas cylinder. That means whenever someone pulls a trailer...
