How to Choose the Right TIG Welder
While TIG welding comes with several advantages over other forms of fabricating, it doesn't mean it is the world's best welding process. Users of TIG welding machines should familiarize themselves with various metal arc fabrication and shielded fabrication processes to gain maximum benefit. While this fabricating process comes with a long list of advantages, it isn't the right process for all applications. The following are factors to consider when looking for the right TIG welder.
A Small TIG welding machine is light, and users can move them around. Contrary, the larger units can weigh up to 100 pounds, and users might need to use a cart to move them around their workshop. Small welders are still versatile and come with enough power to complete projects that require a shorter duty cycle. After considering the power output and duty cycle of a welding machine, portability is often the other factor that welders have to consider.
Of course, welders have to control the amount of heat they apply a metal. Advances in the welding landscape have enabled inventors to create thousands of pulses per second, which is an increase from 20 pulses per second on the old TIG welding machines. A welder can use pulsing on thin metals or stiff joints that can rust or burn when subjected to extreme much heat. The higher the pulse rate a welder has, the stronger their weld will be as it will give them control over their weld puddle. A higher pulsing rate also constricts and focuses on the arc, and this can help fabricators limit the heat they apply to the weld. With a higher pulsing rate, welders will have less extra metal to remove and travel faster along the weld, resulting in a clean weld. With the best welding technology, fabricators can create excellent welds and save on material and time.
Water-Cooled Torch vs. Air-Cooled Torch
While metal fabricators can go with a water-cooled torch, there are times they wish they had an air-cooled torch. Of course, the torch will heat up at a higher power output, but most welders are okay with it. In contrast, a water-cooled torch comes with a smaller head that enables TIG welders to make their welds fine even in tight spots. A water-cooled torch also spares welders the extreme heat generated on industrious projects when an air-cooled torch can't handle it.
Foot pedals that are reliable are essential in any TIG welding project. Metal fabricators often do their tasks in awkward positions, and both of their hands are needed to hold the filler rod and the torch. With a reliable foot pedal, a TIG welder can control power usage to ensure their pedal doesn't become too large. Welding machines with unreliable foot pedals often slope at a high angle, causing foot fatigue. Metal fabricators should make sure their foot pedals are responsive as they adjust the level of heat generation.
Operating at higher frequency settings enable a TIG welder to control the arc and maximize their output. As such, fabricators might need to inspect their welding machines to ensure everything snaps into the position, especially when one wants to move around their workshop with the TIG welding machine.
For greater versatility and extra features, metal fabricators should go for a machine that has both plasma cutting and stick welding capabilities. These capabilities will increase the range of potential projects and help TIG welders save on metal fabrication by enabling them to complete any project that comes their way. Metal fabricators might also need to consider the quality of the arc because cheaper models tend to have stability issues.
