I like Miller Electric because of their people and their service. The best thing Miller has going for them is that when one of their welding machines breaks, They have great customer support.
The purpose of this article is to explain how to get the most out of your 115v wire feeder Portable Welding Machine and to make sure you are getting proper penetration in what you are welding.
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!
Generally speaking, smaller is better. A water cooled 250 amp tig torch is smaller than some 100 amp air cooled torches. Bigger torches are ok, just harder to manipulate in tight spots. A #7 tig cup is a good place to start.
Nowadays, welding machines have become affordable. However, the cost of hiring a professional welder to do some basic welding jobs around the home remains expensive. Armed with the knowledge on how to weld, any homeowner can save a good amount of money which would otherwise have been used to pay the welders. All that is needed is a little practice to start the welding.
The world of Lincoln SA200 welders is an interesting one. Lincoln wound some of them in the 1970s with aluminum, but went back to copper with the Pipeliner Classic Series ll. Stay away from aluminum if you’re going to get a Pipeliner.
Spatter, burn backs wire not feeding properly and so. What’s going on, they think to themselves. “Ahh, I know, it must be a worn contact tip”. So off they go and replace the contact tip with a new one. But no, sure enough same problem. “Well, it’s been a while since I change the liner”. So off they go and do that. Yet sure enough the same problem is still there.
At first you need to turn on the welding machine. An electric arc is being generated when the welding rod comes in contact with the juncture of fusion. Generally, Tap Starting and Scratch Starting, are used for the process of electric arc generation. In Tap starting method, an electrode is used to tap on the work that removes excessive flux from electrode tip, which meanwhile creates an electric contact to generate the arc. While in scratch starting method, the rod is made to scratch against the surface of the work slightly and as the spark is generated, the rod can be lifted off. Also, remember not to put extra pressure in the method, because through this the rod might get stuck to the work medium.
