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...
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 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...
This is Part 2 of the “making a belt guard for an air compressor” video. If you missed the first one, click “Video of the Week” in the top bar, and Part 1 should be the second one down. In last week’s video we left off with the sheet metal all tacked up and...
Mig like Tig like ZT fab is what this weekly video is all about. Over at WeldingWeb.com there is a long thread on the topic “Mig like Tig”. There is a guy with username ZTfab who can make some of the prettiest “stacked dime” mig welds you ever saw. Personally, I would really like...
