TIG Welders Buyers guide
Inverter technology gives you more control over your welds and makes your job easier. This allows you to adjust the weld’s bead profile enabling you to make the bead wider and narrower. This enables you to get the correct size and eliminates under or over welding. Under welding will require a second pass resulting in a weaker and less tidy weld. Over welding will require more sanding/filing and more cleanup, in general, adding to the time you spent on a task.
In summary, inverter technology allows you specify the size of the bead and therefore the perfect finish to your weld. Getting this correct saves you time and effort and creates a better result.
Auto hot start
TIG welders need to be warm to start welding efficiently. However, it is difficult to warm a welding torch up without welding with it. Therefore without auto hot start, you will often have to weld with scrap metal to warm up the machine. This wastes time and material. However, auto hot start enables you to start the welder with the torch hot. This leads to good welds straight away and reduces wasted time or bad welds from starting with a cold-welding torch. Welding when the torch isn’t sufficiently hot will result in weaker and messier welds that will require more clean up afterwards.
Anti-stick can work to automatically adjust the voltage and or amperage to control the heat and length of the flame or arc of the welder depending on your settings.
For example, if you are using manual or programmed settings designed for specific metals the welder knows this. If it starts to stick or catch in the same spot for too long it could be because the welder is melting the electrode to what you are trying to weld. To avoid this the anti-stick function will reduce the voltage to reduce the heat of the welder. It could also increase the amperage to reduce the length of the arc. This should free the welder from whatever it is stuck to and then the welder will resume its normal welding voltage.
Arc force stabilization
Arc force is the correlation between amperage and voltage. Arc force stabilization allows these two variables to be very consistent by stabilizing them. So, for example, when using a shorter arc length in your setting the voltage will drop. With arc force stabilization, the machine will then turn up the amperage to maintain a consistent weld.
This helps you achieve a consistent weld that is clean and strong. If the voltage and or amperage are changing the heat and length of your flame is going to change with it. Thereby your weld is going to change as you are welding leading to inconsistent welds. Inconsistent arc force will lead to weaker and messier welds.
Thermal overload protection
Thermal overload protection is linked to the % duty cycle of your machine. It is also linked to the fan cooling of your machine.
When the machine gets too hot, the thermal overload protection will kick in turning the machine off to allow it to cool.
In addition, if when you have welding for a certain amount of time and have reached the % duty cycle of your machine, the thermal overload protection will kick in to allow the machine to get the required downtime it needs to cool down and be ready to weld again.
Fan cooling system
Having a fan cooling system is very important in a TIG welder. By cooling the TIG welder it will keep you welding as long as possible before the welder needs a period to cool down.
Without adequate cooling, you won’t be able to weld as efficiently as possible and it will slow all your welding tasks down.
% duty cycle
The % duty cycle of your TIG welder is important as it affects how long you can continue welding before the machine will need a “cooling off period”. The higher the per cent cycle the longer you can remain welding keeping you efficient as you don’t have to wait for the machine to cool down. If your welder has a 60% duty cycle you can weld for 60% of the time and it must be off for 40% of the time so in a 10-minute span, the machine needs to not be welding for 4 minutes.
Compact / lightweight
Some scenarios require you to move the TIG welder. When this happens, having a lightweight and compact TIG welder is a must as it makes your job much easier. If you are working on large projects, you will need to reposition the welder to get to every part of a large project.
If you are new to welding and are yet to have a designated spot for your welder having a compact and light model that can be stored out of the way is handy.
Accessories are an important part of welding in general. If you are buying a welder for the first time you might not have any of the accessories, so buying one that comes with some of the important ones will save you the hassle of finding them and ensure that you can start welding straight away.
The accessories you need will vary depending on what you are welding so it’s advisable to research and source gasses or different rods depending on what you need to weld. However, you will definitely need a torch, welding gloves, earth clamp and a welding mask. If your welder comes with these accessories it can save you time and money.
Having a warranty shows that the manufacturer is confident in the product they have made. Also, if anything goes wrong, they can fix or replace it for you.
It is recommended that you buy a TIG welder with at least a 1-year warranty.
What is a TIG welder?
TIG stand for Tungsten Inert Gas. For TIG welding you don’t have an automatic wire as with MIG welding. Instead, as you are welding you use a metal rod that you manually position into the spot where you would like the filler material to be placed.
While you are using a TIG welder, tungsten gas is being blown out of the torch. Tungsten gas is an inert gas that has two purposes. Firstly, it protects the weld from the atmosphere which stops any reactions taking place and ensures the weld is strong and clean. Secondly, it helps to cool the weld down, so it sets properly and creates a strong bond.
What is a TIG welder used for?
TIG welders are good for most metal welding providing you use the correct rod. They are particularly good for welding two different metals together whereas some welders can only work with the same metal. You can weld most metals with a TIG welder, but it is worth double checking your metal before you start.
TIG welders shine when you have a difficult or awkward weld such as a curved weld or welds at an awkward angle. The TIG welder allows you to be very precise but also quite free-flowing allowing you to complete difficult welds more easily.
How to use a TIG welder?
Firstly, you will want to choose the right rod for the material you are working with. If you are new to welding it’s advisable you start with some scrap material and just practice joining it together. A good starter material is aluminium. To weld aluminium, you will want to use a pure tungsten rod. This rod will need to be sanded/ground to a point.
The rod will need to be placed inside the collet which is the tool you hold in the other hand to the torch. You will want about ¼ inch of the rod to be sticking out from the end of the collet.
Your TIG welder should have preset options of AC, DCEP and DCEN. You will want to use the AC setting if you are practising on aluminium. You then choose the settings for cleaning/penetrating, air and amps. You can find tables online which help you select the right settings for each of these.
Prepare your pieces on a welding table. Clamp your pieces so they stay securely in place while you weld.
Don your protective equipment including a boiler suit, face and eye protection and thick welding gloves.
Your first job is to tack the two pieces of metal together so you can get the clamps out of the way. To do this create a few points between the clamps. Start at one edge and when a pool has formed, touch the rod in. Once this is completed you can remove the clamps.
You are then ready to start welding. Hold the torch in one hand and use it to melt the metal rod fitted into the collet in the other hand. When welding work slowly and carefully. Your aim is to melt the tungsten rod to bridge the gap between your two pieces of metal.
How does a TIG welder work?
TIG welders work by melting a metal bar or rod into the gap between two pieces of metal. This metal then cools and hardens joining the two pieces of metal together.
TIG welders have tungsten tips and blow out gas from the torch. This gas has two purposes. Firstly, it protects the weld from the atmosphere which stops any reactions taking place and ensures the weld is strong and clean. Secondly, it helps to cool the weld down, so it sets properly and creates a strong bond.
How to convert an arc welder to a TIG?
Converting an arc welder to a TIG welder is possible. You will need to buy a TIG Welding Torch Kit for Arc Inverters. These normally work by using a different torch. By attaching a TIG welding torch to the negative socket on your arc welder and using argon gas you will turn your arc welder into a TIG welder.
