Mig Welders

Those little 115v wire welders that you see at Lowes and Home Depot are selling like hotcakes. Home Depot seems to always stock the Lincoln Electric Weld Pak HD. And Lowes seems to always have the Lincoln Electric Pro Core 125 MIG/Flux-Corded Welder. Every time I visit Lowes or Home Depot, I cant help but notice that the welding supply shelves have grown like crazy in between my frequent visits.

My theory is that cable TV shows like Orange County Choppers and Monster Garage and helped to bring welding and fabrication more into mainstream Americana and have even created quite a buzz around welding and fabrication. It seems like every red blooded American male with an ounce of testosterone in his gonads wants to make something out of metal and the only real way to do that is with a welding machine. Having a welder in your garage also gives some serious bragging rights and makes you think you have a lot more friends than you really do, (kind of like having a Bass boat).

But the thing that scares me a little and should scare a lot of folks is that there is no welding police. No one to blow the whistle and stop people from welding stuff they shouldnt oughta weld. Its kind of like a sixteen year old being free to stroll into a motorcycle shop and ride off on a crotch rocket that will do 180 mph. I guess that is part of living in Free America.

What a country!

These little wire welders do have some limitations. Lets be clear about that. There are just some jobs you should not tackle with a 115v mig welder.

But take heart. There are many jobs that you can do, and do well with one of these 115v welding machines.

The purpose of this article is to explain how to get the most out of your 115v wire feeder welding machine and to make sure you are getting proper penetration in what you are welding.

First off, if you are going to weld a thin sheet metal quarter panel patch for a Nissan Altima, no worries. Penetration will be the least of your concerns. But if you are thinking about welding something heavier like a home-built Hummer Kit using 3 inch square tubing with 3/16 inch wall thickness, that is something else entirely. This is a situation where you will really be pushing the limits of any 115v wire feed welder.

I think anytime something is welded that that would probably injure someone if the welds fail, a 220-230v MIG welding machine should be used. That said there are still going to be occasions where people will need to push the limits of their 115v MIG welding wire feed welders.

Wire Feed Welder

Here are 7 things you can do that will help to increase your chances of penetration when you really need it.

1. Use flux core wire like Hobart Fabshield 21b and set the machine to max voltage, then adjust wire feed accordingly. Flux core just plain penetrates better that bare wire on 115v wire feeders. Make sure you follow the recommendations on the wire for polarity. A lot of disappointment has come from not changing the polarity when required.

2. Plug into a dedicated 20 amp circuit. Most household circuits are 15 amp. You might have a 20 amp in your garage. If not, consider getting one.

3. Do not, I repeat, do not use an extension cord. If you must use one you better use the shortest and thickest one you can find to avoid a power drop. Even then your machine will probably weld like it has been castrated. Get it? No balls. Ok moving on to #4.

4. Preheat the joint even if it is with a little propane torch, warming a joint up to even 150 degrees is like having another 10% extra amperage.

5. Do not weld downhill. Instead, weld uphill. Vertical uphill welds get more penetration than any other position joint because gravity keeps the puddle behind the arc.

6. Clean the metal with a grinder. Not having to penetrate through hot rolled mill scale, rust, or paint will greatly increase your penetration.

7. Get some small pieces of metal of the same thickness as the welding task at hand and weld a T joint. Then break it with a vise and a hammer. If it breaks easily you have problems and need to adjust the machine and/or technique until you can weld several joints that either do not break, or if they do break, show good penetration in the corner of the joint.

If you follow these 7 welding tips for getting better penetration with your 115 volt wire feed welder, you will be getting the most out of your mig welder.

Know More about Welders

The welding process is done by the welding machine and even by the welders too. It is a very well known fact that the concept of having different type of welding process and each of the process has its own welding machine.

Moreover we will see now the various types of welding machine and its types in brief. Firstly, we will discuss about plasma cutters. This process is also known as child of modern invention, this process also uses science in there process.

It also uses the plasma gas and perform multi task of cutting and welding. Totally in market there are nine plasma cutters and five of them are listed as super cut fifty super cut sixty, super cut forty, super cut fifty P, power plasma 50 power plasma sixty and power plasma 70 and also power plasma 100, power plasma 80, plasma machines is also available for processing.

These machines are classified under the category of inverter types of welding machine. These machine falls on the category of different types of tables like the first three falls under MOSFET and remaining comes under the category of IGBT.

These machines can be used typically by all industrial process by the welders, and it is also designed keeping in mind of having torch track operation and adjustable post flow cooling yet it is portable.

These machines are very user friendly and makes the user very comfortable .the next new invented machine on the row is TIG welders and it is the most widely used machine and it is in demand and well appreciated for its portability and economy.

The repair of the machine on the field is a very easy process and can weld any type of stainless material or steel. It could be any setting the machine will not have any problem in its usage and also serves us with the unique combination of both amperage and features affordably.

All About Types of TIG Welders

TIG welders are of five types which is easily available. They are power I TIG -200 power TIG 200 DX, power TIG 250 EX, power TIG EX, power TIG 225 LX, power TIG 315 DX.

The starting minimum voltage required to start the unit is 220/240v it can also afford consistence and stable parameters with the standard feature being with foot pedal control.

There are machines which comes with the advantage and special features like arc force control , spool gun capability, digital display, consumer low power and many more which is specially designed so that these machine can be used in all industrial purposes and serve all industrial process, such machines are easily available and are called MIG machines.

They are namely I MIG 205, I MIG 160, I MIG 250, and I MIG 200. They are different types of MIG machines available for various uses. The power arc welder is also known or commonly known as stick welders.

They are two types of stick welding machines available they are power arc 200 and power arc 160. These machines gives good competition and leads the industry with there performance and the price too. It also gives the benefit of excellent arc characteristic.

So when talking about welding process, the welders have various options in different type of welding machine and the welder or the user can weld ant type of metal easily and can be satisfied with a smooth welding characteristic with a high duty cycles. Enjoying the benefits of the machine can be fullest only if u select a machine which is best suits your work.
