Buying Guide to Select the Best Inverter Welders
Before purchasing tools, it is very important to understand what they are, how they work, and what types of variants exist. This will help you identify the product that best suits your needs. For this reason, in our article, we will try to clarify the most frequent doubts and questions regarding this type of tool.
What Are Inverter Welding Machines?
Inverter welders are relatively new and innovative welding tools that have numerous advantages, still unknown to many people, compared to conventional models. Among the main advantages of inverter welding machines, we find their compact dimensions, which make them easily transportable, even inside a light carrying case.
They use much smaller transformers and consequently weigh less. This is one of the main differences with conventional welders, notoriously robust, and not suitable for confined spaces.
What Are the Most Used Welding Processes Nowadays?
Throughout history, various welding processes have been used and refined. As always, some are more popular and appreciated and are therefore more used than others. The four most well-known welding processes are MMA, MIG, TIG, and FCAW welding.
- MMA or Electrode Welding: (also known as SMAW welding for its abbreviation in English) uses a metal electrode coated with a filler metal to be able to weld the original material.
- Mig Welding : (also known as GMAW welding for its abbreviation in English) it uses a wire welding electrode on a coil that automatically feeds at a pre-set constant speed.
- Tig Welding: (also known as GTAW welding for its abbreviation in English) is an arc welding process that uses a non-fusible tungsten electrode.
- Flaw Welding with Cored Wire: Similar to MIG welding in that it uses a wire feeding process. This type of welding, however, unlike the MIG case, does not require an external protection gas.
What Dangers Are Related to Welding?
The welding activity can present various dangers, both for those who are performing the welding and for those who are nearby. Therefore, it is important to know not only the risks and dangers related to this activity but also the safety measures to be adopted (which we talk about in the next paragraph). Let’s see the dangers together:
- Electrical Discharge: This is the most serious danger due to welding, it can cause serious and even fatal injuries, both by direct discharge and in the event of a fall from above after receiving a discharge. Touching part of the welding circuit or electrode while touching the metal being welded, there is also a risk of a secondary electric shock.
- Risks Related to Noise Pollution: When we perform welding, we expose ourselves to loud and prolonged noises. Noises with more than 85 dB (decibel) are considered loud, and welding activities such as flame cutting and arcing can produce noises with more than 100 dB. Exposing yourself regularly to loud noises can cause permanent hearing loss.
- Uv and Ir Exposure: Exposing yourself without personal protective equipment (PPE) or other types of protection to the intense UV light that is produced during welding activities can cause corneal burns. The severity of the injury depends on the distance, the duration of exposure, and the angle of penetration. Long-term exposure to arc flashes can also contribute to cataracts and vision loss.
- Exposure to Fumes and Gases: Welding exposes the welder to invisible gases that can easily penetrate the lungs, including ozone, nitrogen oxides, chromium and nickel oxides, and carbon monoxide. Depending on the gas or smoke, concentration, and duration of exposure, the damage caused can be more or less serious.
- Burns: The combination of high-temperature welding arcs, UV rays, and molten metal can cause severe burns during welding. These burns can affect the skin or eyes and can be very serious.
What Safety Measures Are Needed to Use an Inverter Welder?
We know that when using this type of equipment inadequately or without using the necessary precautions, problems can occur that put our lives at risk.
It will be really important to use personal protective equipment (PPE). If we have a superior who assigns us jobs involving welding, he will be obliged to provide us with:
- Welding helmet or mask with side shields: to protect us from UV radiation, particles, debris, hot slag, and chemical burns.
- Flame retardant hood: to be worn under the helmet to protect the back of the head.
- Respirators: protect us from the fumes and oxides that the welding releases. The respirator must be suitable for the type of work we are carrying out.
- Flame retardant clothing: to protect us from heat, fire, and radiation from the welding process and to prevent burns.
- Fire-resistant ear protection and earmuffs
- Fire-resistant ankle boots and gloves: safety ankle boots with a rubber sole and steel toe protect us from electric shock, heat, fire, burns, and falling objects.
- Remember to forbid children from approaching the welding area.
In addition to these individual measures, it is important to have received adequate training and make sure that there are no flammable materials in our workspace. All operations (device preparation, welding, maintenance, repair) must be carried out by qualified personnel.
What Are the Pros and Cons of An Inverter Welder?
Although some people still have doubts about the veracity of the advantages attributed to inverter welding machines compared to traditional ones, these innovative models have become very popular among users thanks to their characteristics. In this table we see the main ones:
Advantages
- Small, compact and portable
- Sophisticated and lightweight silicon transformer
- It uses an IGBT transistor for insulating gate capable of performing high volume soldering
- They consume less energy
- They use normal household connectors
- They operate with lower voltage
- Electronically adjustable output power
- They allow you to adjust the power in a wide range
Disadvantages
- Maintenance is more expensive
- They have a more complex structure
- They are equipped with multiple electronic components
Type of Process (technology)
The first criterion to consider is the type of welding we want to perform. That is, first of all, we must define what type of process we will use, on what materials we will work, and under what conditions.
These factors will depend on the choice of technology and, consequently, of the welder to buy. Consider the characteristics of each welding process to make your choice. The cheaper inverter welders are generally designed to use MMA or electrode welding technology.
However, depending on the range, the manufacturer, and the quality of the device in question, there are models that can work with more than one technology. Logically, these are more expensive machines.
Adjustable Amperage and Power Levels
The amperage with which the welder works will determine the power with which the machine works. Generally, the higher the power and the better the performance, even if this is not always the case. The inverter welding machines have an amperage of between 100 A and 250 A.
The amperage affects the adjustable power levels. The inverter welding machines are normally equipped with a minimum amperage with which they can work, which can oscillate from 10 A up to the maximum amperage supported by the machine.
If you have to work at different intensities and levels, it is better to look for a machine with a wide range, say from 20 A to 200 A, for example.
Working Cycle
The work cycle is a very important technical feature: it defines the number of minutes, within a period of 10 minutes, during which a welding machine can produce welding current safely. So a 140 A welder with a 60% duty cycle must “rest” for at least 4 minutes after 6 minutes of continuous welding.
Look carefully at the specifications of the welder you are thinking of purchasing. Many manufacturers of welding machines identify the different models based on their maximum ability to generate energy but are careful because often the machine in question can only produce that level of energy for a short period of time. For this, always try to check the work cycle.
Diameter and Type of Electrode
The electrode establishes the arc, protects the molten material, and, by wearing out, joins the molten material of the base metal, making the weld. On the market there are electrodes with standardized diameters, the most common is 1.6 mm, 2.0 mm, 2.5 mm, 3.25 mm, 4.0 mm, and 5 mm.
A welding machine that allows you to use a wide range of these diameters will guarantee greater versatility. As regards the different types of electrodes, there are for example rutile, basic, cellulose, antioxidant, and bronze electrodes.
Some welders work only with certain types of electrodes, obviously, a machine that supports different types will be more convenient and more versatile. The electrodes can be further classified according to the materials to be welded.
