I had a chance to do a review on a Hobart Trek 180 mig machine and I really put it through the ringer. Most welding machine reviews I have read only go so far as running a bead or two. I did that too, but I took it a step further…
This can be a portable process with the help of a portable stud MIG Welding Machine. This is a very flexible type of welding and can be used in automobiles to work on the bodies, it can be used to weld electrical panels and in construction of ships or buildings.
Joint preparation is the part of welding most people never think about. We concentrate on welding techniques and anything else that seems to be the answer to a better weld! The fact is no matter what welding process is chosen the joint set-up is the first part of producing a sound quality weld. What you put in is what you get out! A dirty joint or improper fit-up will make the best welders fail at their job. If you spend some time properly fitting up and preparing you weld joint; the welding part will become much easier. The last thing you want in a weld joint is moisture, paint, rust, mill scale, or anything else that does not belong there! If you work with clean metal, and a clean weld joint, the only thing left is a clean weld. Don’t expect the weld to clean itself because that is your job!
Even after being informed about the latest processes used for coating quality steel fence panels, many people don’t know how they would benefit from having steel rather than aluminum. The biggest advantage steel has over aluminum is strength. Aluminum fences are nowhere near as strong as steel fences of the same size. If an aluminum fence is exposed to much abuse, it’s going to bend and maybe even break. This is something that needs to be taken in to careful consideration before installing one in a location such as a park that’s going to have a lot of people around it. Things such as kids trying to climb it are inevitable.
Because what happens behind the scenes is the company you bought the wire from has a big argument with their supplier in China or where ever. And they say stuff ya….well go next door and buy from them. Hey with over 300 manufacturers in China alone they can pick and choose who they like.
The test metal was 3/8″ thick and was welded in the vertical position. The root pass was welded downhill and the rest of the welding passes were done uphill.
It is never a bad Idea to preheat, in fact, almost every welding job I perform professionally demands a preheat temp of 400 degrees and up. You will be amazed at how easily the arc strikes and how well the welding rod burns, improving welding quality significantly. Bear in mind, once the steel has reached preheat temp, this temp must be maintained through out the procedure till all welding is finished.
Welding equipment for sale are available all over the Internet. What you need to be thinking about is how much you are willing to pay for your welding machine. If you want to pay the most money than you can get a new welding machine, but you will be paying a lot more than if you get a usable machine. Use welding equipment can be just as good as new ones, but they dont come with a shiny new packaging and sometimes they will carry less of a guarantee than new welding equipment. This is completely up to you.
