Our TIG Buying Guide
Whenever you’re shopping for the best TIG welder, the main factors that should determine your choice are:
- What types of projects will you do the most?
- What specific functions do you need?
- What is your budget?
What Types of Projects Are You Planning to Do?
TIG welding is most suitable where bead appearance is important, like in bicycle frames or on truck bumpers, lawn furniture and the like. It also is the most appropriate way to weld very thin sheet metal, because stick and MIG processes put too much heat into the metal and result in burn-through.
Aluminum and stainless steel are the other main places where using a TIG welder is the best way to get the work done, because of its penetration and lack of contaminants in the weld.
What Kinds of Functions are Required for Your Work?
Although it’s possible to weld aluminum with DC current, you will frequently see the rule that you must use AC output to weld aluminum. One reason for this is that AC welding allows the use of high-frequency pulses that keep the weld puddle clean. Another reason is that a primary advantage of TIG welding is heat control, a highly important factor in welding aluminum.
Options to look for in regard to available functions are AC vs DC capability, plasma cutter, ability to select the AC waveform, for example square wave or true sine wave and an adjustable pulse rate.
Multi-Process Machines Offer More Functions for Your Money
A multi-process welder can give you more versatility for the same money. Sometimes they can offer MIG or plasma cutter ability along with TIG.
How Much Can You Spend on Your Machine?
In the end, there are enough functions and technology choices available when buying a TIG to drive welder costs to the same level as building a house.
It’s important to decide what functions and equipment are most important and staying under your final number to find the best TIG welder for the money. Don’t forget to take the length of the warranty into account.
What to look out for
Some equipment is essentially necessary, such as a foot pedal to control heat or a flow meter-type gas regulator.
Does the TIG welder you’re looking at include these items?
Will you need to buy higher-quality pieces to get the real potential out of the welder?
Check The Duty Cycle Rating
Check the duty cycle rating of the welding machines and the output power they’re rated at for that percentage.
Duty cycle is the percentage of 10 minutes in which the welder can operate continuously before overheating.
A 40 percent duty cycle means you can weld for 4 straight minutes at the rated power. That’s actually quite a long time to weld continuously. You will find that the more expensive American machines seem to have much lower duty cycle ratings than the less-expensive Chinese-built welders even though they cost more.
Remember the old adage about something seeming too good to be true.
This has to do with ratings methodology and the fact that the expensive big-name companies are more cautious because their equipment is used by professionals on long shifts over years in tough environments.
Don’t forget to budget in gas cylinders, the cost to fill them and optional but important parts like water cooling.
This is the Big Leagues
TIG welding is a big step up from basic welding skills, and TIG machines cost a lot more than other welders, offering obscure features not found on other machines. Educate yourself at welding forums and manufacturer’s websites on what terms and functions mean before spending your money on something you don’t even need.
With those factors taken into account, we believe the Miller MaxStar STR is the best TIG welder as it offers the most bang for the buck. Features like memory card storage, wireless remote control, Miller’s legendary customer service and the lengthy warranty are some of the big reasons why we selected the MaxStar as our Pro Choice in this guide. Don’t sleep on the Hobart EZ-TIG 165i though, as it offers excellent value.
