How to use a welding machine

You don’t have to be a craftsman to keep a welding machine next to your house. Sometimes it happens that you need one and the neighbor next door can’t be found to lend it to you. But, using such a device is not the easiest task, you have to be careful and follow a few simple rules.

Inform yourself well before you buy it

The market is overwhelmed by models of welding machines that use old or very new technologies. You need to make sure that you choose a technology that fits well with the materials you are going to work on. If you want to be able to weld a variety of metals, even aluminum, only the latest technology, the plasma one, will help you, but it will empty your pockets.

A professional method, good for various welds, which will not have such high costs is the one with electrode. In this category, you will find traditional appliances with inverter. The ones with inverter are more efficient and consume less electricity, even if they will cost you a little more.

Ask a friend for help

Even if you got your hands on a good device, this does not mean that you will perform perfect welds from the first attempt. In general, you will need a period of accommodation and a few lessons to be able to properly glue two metal parts. Thus, it is recommended to ask a friend who has some experience with using this technology or maybe even an expert.

It will be harder at first, but you will learn easier with the help of someone, even an online tutorial, and you will avoid many of the mistakes of beginners. Since you still don’t know how the materials will behave, it is advisable to start with a lower intensity of the current arc, increasing, gradually.

Use protective equipment

Of course, welding is a complicated job and working with equipment in this sector can endanger your life if you do not protect yourself properly. You need a non-flammable suit and apron, specially made for this, a pair of gloves of the same kind and a protective helmet to cover your whole face and possibly your neck.

If you can afford it, you can also buy a pair of slippers, specifically for this activity, which you will be able to use at other times when you have crafts around the house. It is preferable to weld outdoors due to the toxic substances emitted. In addition, always be careful not to touch the metal during welding and do not look at the welding flame without a mask or goggles, as this can affect your eyes. 

Provide proper maintenance

A welding machine can take you many years, if you take care of it properly. First of all, closely follow the specifications recommended by the user manual and do not overload the device. If one of its cables or accessories has failed, then call an authorized service center and do not perform the repair yourself at home. Make sure the electrodes are dry before use, make sure there are no flammable substances around. Also, check that the power, ground or electrode wire is well insulated before each use.

Popular brands:

The best welding machine will prove to be very useful, whenever you want to glue two objects made of metal / thermoplastic materials or make more complex parts for your household, especially if you do not have enough money to pay a qualified welder or if you like to do things on your own. Either way, you need to know what type of device is suitable for the task you are proposing, so to get the best performance for your project, we recommend one of the manufacturers listed below.

How to choose a good welding machine

Buyer’s guide

Many enthusiasts of crafts and repairs consider it somewhat necessary to know at least the basic utility for the best welding machines currently used.

 Devices in this category can help you make changes in the household, turn welding into a profession or develop your creativity when practicing sculpture by welding.

However, you simply cannot buy the first device that comes your way, when you have something to weld and that is why we suggest you to inform yourself thoroughly about the standardized work kit specific to this job. 

Only after you have built yourself in terms of the technical capabilities of a type of product, you can try to determine where professional users can find welding machines at a good price.

 Here’s what interests you most:

Typology: can use multiple working methods, as we can list: electrode welding (MMA), wire welding, inert gas medium (TIG) welding, oxyacetylene flame welding. 

There are also newly patented methods, such as plasma, photon beam or electron beam, less commonly used conventionally. 

If you want a professional method, choose the MMA option, ie electric arc welding.

In this process, a consumable electrode is heated and melted by closing an electrical circuit so that the two metal parts are glued together. 

As subcategories, you can choose between traditional and inverter devices, with the difference that the first version consumes more energy and offers lower efficiency, while the second is newer, slightly more expensive, but also more efficient.

For very fine welding we recommend devices that melt a metal wire, and not an electrode. 

If you are preparing to practice welding that will only require some basic knowledge for work, it is good to practice with an oxyacetylene flame, also used for cutting or drilling metals. 

Here you need a tank for the substance, which limits the mobility of the device.

The most durable and versatile method is the one with gas protection, in which case the electrode does not melt, because it is not made of filler material, but of tungsten. 

In addition to conventional metals, this method has the ability to weld materials that show affinity for gases (titanium, zirconium), argon being most often used to protect against contact with air.

Welding material: can be steel, stainless steel, cast iron, aluminum, copper, titanium, etc. When you work more on steel or stainless steel, almost any type of device will cope with the challenge. 

Aluminum is one of the most difficult materials to weld, having high conductivity and easily deforming in the presence of high temperatures, as a result, a TIG device or any other version that works on alternating current will be used, avoiding electrode devices. consumable.

You will use them only when the aluminum layer is thick. As already mentioned, for titanium, copper and other less commonly used metals, a non-additive electrode model is essential. 

It is considered that the latest generation products, with plasma, are suitable for welding any type of metal, but the acquisition cost will be considered relatively high.

Supported electrode material: can be additional or permanent. The most common versions of addition electrodes are: rutile, basic or cellulosic. 

For a very fine weld, which can be done in any direction, even vertically, you will choose devices that use rutile electrodes. 

Their advantage is that it handles well at direct and alternating current, and the electric arc obtained has high stability.

However, the quality of the joints will be lower and more vulnerable in terms of resistance to mechanical shock. 

For conventional welding, most basic electrodes are used, even if a lot of additive material is consumed, but the joint will have increased resistance. 

The less advantageous aspect is the fact that only the devices that operate in direct current parameters will use them, and the stability of the electric arc will be a precarious one.

If you plan to weld pipes, make sure that the model you want to buy can use cellulosic electrodes, these being the most suitable in that situation.

Efficiency level: is described based on the ratio between the energy consumed, the quality of the weld and the purchase price of the device.

 If you are more interested in the quality of the device and the performance indicators, choose one with an inverter, even if you will make a bigger investment. 

Welding inverters not only offer the advantage of using direct current and implicitly advanced electrical control possibilities, but also guarantee the opportunity to work with any type of electrode, generate high melting power and have a very low energy consumption.

When you are not ready to invest more funds, you will choose a traditional version of MMA device, ie one that uses only rutile electrodes and offers the method of operation only in alternating current, these examples being large energy consumers. 

Gradually, those versions will be almost completely replaced by inverters.

Manufacturer: can be a good clue, when you try to find out where professional welders can find welding machines at good prices.

 Here are some important names that offer products on the Romanian market: Telwin, Einhell, Proweld, ASN or Ergus. The most popular are from Telwin, because they are available in multiple variants, and the purchase cost is moderate. 

Ergus produces high-performance devices, which are a bit more expensive, but mainly from the latest generation range. 

If you want a cheap and good welding machine, you can choose one belonging to the Einhell brand, because in the case of this supplier the prices can be lower.

By going through all these features on your waiting list and after viewing several opinions about the best welding machines, you will be able to personally select the device suitable for your needs.

 Whether you are only interested in a cheap model or, on the contrary, a professional product, you will find almost any option to order online.

 We suggest you buy something from the internet for two main reasons: the price may be lower than in stores, for the same model, and the policy of the supplier sites allows you to return the offer, if it does not meet your expectations.

 Following is a short list of the most popular current products.
