TIG Welder Inverter Vs Transformer: A Guide that will help you decide

Check out the comparison between TIG Welder Inverter Vs Transformer. In the case of Electric welders, you may hear from many people that the bigger project can use some extra power so which one you need depends on what kind of work you are using a TIG welder for. That is somehow true but if you know the extremes of your project, material, and the welder machines then half of your issue is resolved.

But then we still have a question from amateur welders, TIG Welder Inverter Vs Transformer? Honestly, we think it is a serious debate for many people. You will hear mixed reviews but again it all depends on the product and the material.

Inverter Vs Transformer TIG Welder

Both have their own advantages from garage welding projects to industrial heavy-duty machine welding. Therefore, we have gathered some basic information about both welder machines and how you can utilize their power in your projects. Both have some serious advantages that can help you get the finest work done. So let us dig into what these two choices of machines are!

What is Inverter TIG Welder?

TIG welders Inverter are light in weight and efficient machines that actually calibrate the range of welding power and styles. They are used for simple plate welding and for the joints.
 A single inverter machine can weld a variety of metals from carbon to stainless steel. But there are many varieties of inverters too and most people will recommend DC inverters for carbon and steel but for Aluminum, you can always look for an AC inverter. Another reason for choosing Inverter TIG Welder is that it is available in so many sizes from 130 Ampere to 160 Ampere for 240V.

How does Inverter work?

Inverter basically works on the principles of voltage regulations. Inverter welder converts the AC power supply into the lowest usable voltages as an output. Let say the 240V AC supply will reduce to almost 20V DC output power supply.

The inverters are more beneficial to use because they use a series of components that converts the power into relevant output. It also has amazing control over the electric arc that ensures clean work. The result may seem durable enough but you may find yourself on cold feet when you are working with heavy-duty materials and thick plates.

Another important detail is that the inverter increases the frequency of the primary power resource from almost 50 Hz up to 100000 Hz. You can set your TIG inverter machine by switching ON and OFF your power plug quickly. Do keep in mind a few of the Inverter welder problems too. The most common problem is not understanding the working of the inverter that may lead to damaging the machine. And repair costs will be costly!

Advantages of Inverter welder

  • Inverters are compact and lightweight
  • They consume less power
  • Good control over the electric arc

Disadvantages of Inverter welder

  • Repair and maintenance are a bit costly
  •  Bitless durable

What is a TIG welder Transformer?

The TIG welder transformer is basically a high-powered machine that just perfects for the main power supply. They are used for welding heavy-duty materials like industrial foil plates, discs, and rods.

Since the welding power is amazing for this one, thus you can fearlessly use it with almost any material. Do remember you can even get a MIG welder transformer if you are specific about what kind of technique of welding. Usually, the welding transformers come in sizes from 250 Ampere to 600 Ampere for 415 voltages.

How does it work?

The welding transformer uses AC machines to change the AC from the main power resource into low and relevant voltages with higher amperes. Thus, the heating from the conversion works best with the welding current. This is the reason why it is ideal for working with thick and heavy materials.
The welding transformers also permit the user to adjust the winding distance to the secondary winding. Moreover, a transformer also lets the user select the magnetic shunt near the transformer’s core to approach the secondary output current.

TIG Welder Inverter Vs Transformer

The challenging part for transformer welding machines is the igniting of the electric arc for welding. But once you have ignited the arc, you can easily work with any heavy-duty material. Another thing that most users avoid using the transformer is that once the voltage of the transformers, you may lose the ignition of the arc as well. It is so sensitive that you may find yourself restarting the machine and setting the voltage again and again.

Advantages of TIG welder Transformer

  •  Ideal for heavy-duty repairs
  • Almost maintenance free machine
  • Low on power expenses
  • Durable welding

Disadvantages of Transformer welder

  •  Sensitive to the reduction of voltage
  • Igniting the electric arc can be tricky

Final verdict

Of course, both of the welding machines have their plus points and a little fallback. But by the end of the day, you have to look at the flexibility of the project and your convenience. Just to get an idea of which one you can use; we will say use an inverter for the garage to middle-duty projects. But if you are aiming for hardcore parts and material welding then a transformer welder is just perfect for you. Now the only question that stands is how often you will need them. So choose accordingly!
