Do I need a TIG welder?

Since TIG welding is more specialized, we are going to assume you already have a basic understanding of MIG and Stick welding. In the event you need to a little more information pertaining to these two, more common types of welding, please read one of my previous posts, “As a beginner, what do I need to start welding,” by clicking here.  Otherwise, let’s try to figure out if you might need a TIG welder!

So, you feel you are ready for a TIG welder due to your experience, research and having answered several pertinent questions. Questions such as, which welding method is best for the type of work I will be doing? If not….

TIG Welding

Why you might need a TIG welder

  • If you find yourself needing to weld paper thin metals on extremely low amperage settings, you might need a TIG welder.
  • If an eye-pleasing weld is desired for highly visible parts, you might need a TIG welder.
  • If extremely high-quality welds are necessary, you might need a TIG welder.
  • If building race car or truck chassis out of chrome-moly tubing, you might need a TIG welder.
  • If you weld a lot of non-ferrous metal like magnesium, copper, and aluminum, you might need a TIG welder.

While not a totally exhaustive list of questions, if you answered positively to any of the above we should be good to move forward and discuss what to look for in a TIG welder.

TIG welders can be expensive, can I get by with a cheap one?

Umm, maybe, if your bank account absolutely will not allow you to purchase a quality, name brand machine. But, please think real hard before you plop down money on a lesser (cheaper) brand. You may find you are not able to afford the cheaper one either, especially if it quits working after a short time. And, many times, cheaper brands have service and warranties that are next to useless. Your experience with the cheaper brand could go well or, be so poor you may give up on TIG welding altogether.

Save your money and buy either a Miller or Lincoln Electric brand TIG welder. Great work is easier to create with great equipment. Both of these companies have been around well over a half-century and are the machines everyone else copies. The old saying about getting what you pay for is certainly true when it comes to welding machines. Having said that, with research, you will find people who occasionally report a part failure even on Miller and Lincoln Electric machines. Failures do happen in every industry. But, you should find troubleshooting advice and replacement parts for Miller and Lincoln Electric equipment much easier than other brands.

So which TIG welder is best for me?

Miller makes dozens of different TIG welders with MSRP’s beginning at just under $1,856. Lincoln Electric also makes dozens of different TIG machines with MSRP’s beginning at $1,339. There is a huge spread in pricing from the low end to high end from both manufacturers. This reflects the various machines abilities to do more things better, for longer periods of time. To check prices on Amazon, click here.

You can purchase welding machines that will do more than just TIG, if necessary. Most, but not all TIG welders also have the capability to stick weld. Both manufacturers also make all in one machines that will MIG, TIG and stick weld.

What is Duty Cycle and why should I care?

If for instance, the duty cycle of the machine is rated at 130A/20V/30%, this equates to the machine being capable of running for 3 continuous minutes at 130 amps. Then, needing to remain idle for 7 minutes to cool down. The duty cycle is based on a 10 minute period. (30% of 10 minutes is 3 minutes) If most of the time the user is welding on a setting well below 130 amps, the machine will not heat up as fast and will weld longer than the duty cycle rating before needing to cool down.

In the event, you will be welding at the machines maximum amperage or close to it, you will need to pay attention to the duty cycle rating when deciding on which machine is best for you.  

Is a multi-purpose welding machine what I need?

It is common for TIG welders to also have the capability of stick welding. But, not all of them are dual purpose capable. So, if you desire a machine that can do both, look for them under multi-process welders. There are a few machines that can MIG, TIG and stick weld. Having one machine that performs all three primary welding processes could be very useful, not to mention space saving.

However, keep in mind that a single duty machine (TIG only) at a given price point will most likely be a higher quality TIG welder than a triple duty machine (TIG, MIG, and stick) at a similar price point.

If you have decided a new TIG welder is for you, remember, always buy the best you can afford!
