Process of TIG Welding
The process of Tungsten Inert Gas or Gas Tungsten Arc Welding is a bit different from the process used in MIG welders. It is very precise and demands a great welding acumen. TIG welding is broadly used by experienced welders to accomplish well-finished beads on a variety of metals varying in terms of thickness. While the work is in progress, the arc tends to jump between the specimen and a non-consumable electrode of tungsten to aggravate the temperature and weld the current. Weld oxidation doesn’t take place due to the presence of inert gas shield around the work piece. The shielding gas (Argon or Helium) accumulates around the weld through a ceramic cup called nozzle that turns on the heat. The larger the size of the cup, the more improved gas current is delivered. TIG method has been a great success with thin metals. Smaller cups are mostly used for minor welds, it provides easy access to harder-to-reach portions.
Qualities of a Good TIG Welder
You should always try to look for a TIG device compatible with both Alternating Current and Direct Current welding operations. You never know which option will come handy for the upcoming tasks, while AC welding is typically used on thin aluminum metals, DC is considered suitable for steel sheets.AC feature is particularly necessary for the positive half cleans the oxides on the self-oxidized material and the negative half penetrates the base metal.
Long duty cycle
The technical term duty cycle implies the quantity of load a machine can handle during a time span of 10 minutes. When the duty cycle goes overboard, the unit needs to be cooled down before the restart. By calculating the duty cycle, you get the number of minutes available for welding in that 10 minutes’ cycle. For instance, a welder which has 80% duty cycle is capable of welding for 8 minutes out of 10 before you’ve to break off the work to reduce the heat. Normally, welders delivering 50 to 60% duty cycle are regarded to be of decent quality. High-end machines often extend it to 80 to 90% percent to boost the productivity.
Appropriate heat control is another critical attribute of a quality TIG kit. Heat control is customary, no matter which material of what thickness you’re dealing with. Uncontrolled heat particularly damages thin metals like aluminum, magnesium, causing warp and burn if the heat is too high. Many reputed brands have included a special pulse welding option which helps regulating the heat output and arc steadiness at the same time.
Low arc stability
Arc stability should be ideally less than 10 amps when you’re working on thin metals. Low amperage provides excellent arc control, better crater filling capacity, easy start-up and distortion-free welds. TIG welding technique is extensively applied on thin materials, a high frequency or hot start might burn or warp the material throughout while welding. Look for TIG device which has a background circuit equipment stuffed inside. It ensures a highly steady, low amperage start.
AC balance control
Nowadays, every upscale branded TIG welder has one feature in common and that is AC balance control. This wonderful feature aids the welding action by allowing the user a great command over the length of the positive and negative currents. Thereby, the AC balance control setting option lets you control the level of cleaning against penetration. Some expensive models have gone a step ahead by engineering an automatic setting to help you build precision welds.
A TIG welder you can count on anytime with any metal has to reserve super resilience and sturdiness to tolerate the abuse of extreme temperature. Among the several features used to prolong the life of your welder, a powerful cooling system is of prime importance. If the heat goes past the pre-set limit, all your efforts can be damaged along with the machine itself. Therefore, a cooling fan has to function properly to safeguard the unit against overheating. Automatic Thermal Overload Shut-off is yet another intelligent feature that automatically puts off the system when it turns too hot and restarts only when it’s properly cooled down.
The best TIG welders allow you the liberty to perform multitasking without purchasing additional equipments that cost a fortune. Technologically advanced, feature-packed models from top brands are exclusively designed for accomplishing tasks beyond TIG and stick welding. Although the initial cost of purchasing such products means coughing a couple of extra bucks, it’s definitely going to earn you a good amount of profit in the long run.
Common Mistakes While Selecting a TIG Welder
Choosing a welder loaded with excess features
A very common tendency of many customers is to get lured by the appearance and grandeur of features of a TIG welder. It’s true that most feature-packed models are excellent in terms of quality and performance but why wasting money on the things you don’t need? For example, you can simply avoid a TIG machine offering AC balance control if you don’t intend to weld thin metals like aluminum or magnesium.
A reasonably priced TIG welder must contain a cooling system such as a Fan-on-demand to protect the system from overheating. Though it doesn’t get rid of the need for a capable welding helmet, it’s still better than no protection at all against overheating. An expensive machine that requires you to buy an extra cooling equipment leads to extra cost. If you’re on a tight budget, be smart enough to browse through the several options where the manufacturer offers a cooling system in the delivery package.
Miscalculation of power demand
It’s necessary to be well aware of the power demand and capacity of the machine otherwise you’ll land yourself in trouble when the power output is not in line with the intended welding specifications.
