TIG Welder - Compare and Buy

Find and buy TIG (Tungsten Inert Gas) welding machines from verified suppliers on IndustrySearch. A TIG welds metals by forming an electric arc between a non-consumable tungsten electrode and the workpiece metals, shielding the weld with an inert shielding gas while the operator manually feeds the weld with a consumable metal filler rod.

Things to consider when buying a TIG welding machine:

Know your application - Important factors to know before getting started, are the types of materials you need to weld, material gauge (thickness), welding speed & productivity requirements, cost constraints, portability needs and environment conditions.

• Choose AC, DC or combined output - To weld aluminium or magnesium an AC output TIG welding machine is required, while for steel and stainless steel a DC only output TIG is sufficient. TIG welding machines that offer both AC and DC output are available, for welding a variety of metals.
• Consider the pulses per second for AC TIG welding machines - AC TIG is the method of choice for welding applications requiring accurate heat control, and the greater the settings range of pulses per second a TIG offers, the more accurate the heat control is for welding aluminium, magnesium or thin sectioned delicate parts.
• Choose for appropriate duty cycle - Duty cycle indicates how many minutes out of 10, a TIG welding machine will continuously operate at full power. TIG welding machines for welding small joints that each requires some setup time, can have a duty cycle as low as 20%. But for heavier continuous welding operations a high enough duty cycle is required, to avoid overheating issues and welding downtimes.
• Consider a multi-use TIG - TIG welding machines offering multiple capabilities along with welding are available, such as arc welding and plasma cutting, significantly expanding the machine’s field of application.
