A community for all welders and all processes including brazing. If you've never welded before but want to get started, ask questions. If you're an experienced hobbyist, show off your projects. If you're a professional show off your projects, answer questions, and encourage beginners and hobbyists alike.
There is no best process, only the best process for the welder and application in question. Help each other, don't criticize or judge.
If you’ve seen a question 100 times answer it the 101st time or ignore it. Even better, write a complete, detailed answer and suggest that the mod(s) pin it to the community.

I just received this welded for small tasks around the house. First attempts to weld anything and it is not striking an arc to anything no matter how clean or what material. Finally I tried a quick trigger pull right to the copper on the ground clamp and nothing happened.
Where do I start my troubleshooting or do I just send it back?
Once we were happy with the setup Lulu started welding. Here she's welding the cross bars into place.
We've taken a bit of a leap forward at this point. The floor of the fire box is welded in, we've installed the back of the fire box, and the cross bars for the rear baffle are welded into place.
In the next version of this evaporator I plan to bring an air feed in under the baffle at the back so that I can push air in under the first grate. This rear wall of the fire box is solid.
This is going to be a long post. I will likely have to break it up into parts. So this is Part 1.
In the late winter of 2019 my hand, Lulu, and I built a new oil tank evaporator.

This is my original evaporator. My wife bought it from a local guy about four years before. It worked ok but I wanted to make improvements.
Note that the door doesn't fit well and the legs are the original oil tank legs which are intended to sit on a concrete floor and not be moved. The body of the evaporator is completely open so I had to pile concrete blocks and piece of steel in there to deflect the heat toward the bottom of the pan.
In early 2020 at the beginning of the pandemic my team was laid off by a company that had made some bad decisions, found itself overextended, and panicked. Needing to find something to occupy ourselves my hand and I decided to built the pot rack that I had been promising my wife for 20 years.
Here is how we did it.
This is my hand. She first visited us two years before to make maple syrup and stayed for a month. She visited three or four times then came to stay in the spring of 2020, again to make maple syrup, and ended up stuck at our homestead during the initial covid panic and travel restrictions. She was an aircraft maintenance quality manager who had never welded before. This is the project where I taught her and she cut her teeth.
The pot rack is a simple rectangle with two cross bars. It is constructed of 2" x 1//4" cold rolled flat bar. We started with the outside rectangle sitting on the floor of my shipping container workshop.
The MigMaster 253 is an amazing welder. It's designed for use on a factory or shop floor so it comes with small, hard wheels. Those factory wheels were not up to the job of working in my sea can workshop or from the bucket on my tractor. It used to get stuck when I tried to roll it over an electrical cord or even a nail. I took off the factory wheels and replaced them with large, pneumatic wheels. Now I can push it over 2x4s if I need to and it is much easier to roll out over the threshold of the door and into the bucket of my tractor.
