TIG welders come in various portable units. They are designed for welding from industrial machines, thin and heavy metal; these welders can basically manage anything thrown to them. The only challenge is the cost attached to these units. TIG welding is a specialized process, and with a perfect TIG welder, you can achieve incredible welds. Some brands are more praised as opposed to others; besides they provide a simplified and convenient user interface that is easier for anyone to master within a short time.
You need to understand that the more features a machine has, the more buttons it has. This translates to you consuming fairly sometime figuring it out before you start executing your project. Before you purchase a TIG welder, there are features you should take note of.
Pulsing Technology
Note, in TIG welding, one has to regulate the heat rate employed on the metal. The new TIG inverters can achieve a considerable pulses rate per second, providing approximately 5,000 pulses every second. This is more than what you will get from an old TIG machine. Do you know that TIG pulsing is highly applied to complicated joints or in scenarios where burning can occur like thin metals?
With a high pulsing rate, you get a more durable weld, which depends on how better you can control the weld puddle. For better results, you need to pay attention to the pulsing technology. Go for options that will save you time and material.
Movability
The smallest TIG welders weigh 40 -50 pounds and are moderately portable. With the large TIG welders designed with a mass of 100pounds and above. This will demand you have a cart in your shop to be able to move such a heavy welding machine. The smaller version of TIG welders come with a lot of versatility and sufficient power to handle smaller jobs successfully. Portability is one of the most significant aspects that welders should pay attention to besides the power output and duty cycle.
Foot controllable Pedal
The TIG welding machine needs to have a reliable foot pedal. In most cases, the TIG projects are handled in an awkward position. Besides, the process calls for two hands controlling mechanisms. You will need to use two hands to hold the torch while the other controls the filler rod. With the pedals, you will control the heat consumed to keep the weld puddle at a manageable size, making it not too big. Make sure you have the right foot pedal that will keep you on maximum control without foot fatigue. You can buy a TIG welder and add to it a foot pedal customizing it to suit your operations.
Easy Controls
If your welding demands you move around, make sure you choose that will minimize risks involved. Imagine the danger of knocking the controls accidentally when in the midst of your project? Make sure you examine the welder’s controls before purchasing to ensure they are firmly and securely positioned.
