The Eastwood 200 Amp Digital TIG welder has all the features of a professional machine but at a fraction of the price. Manual Arc (Stick) – DC Positive/Negative with Hot Start and Arc Force control to prevent rod stick and superior arc control. DC TIG – Weld Steel and Stainless Steel DC TIG/Pulse – Minimize warpage and prevent blow through on thin Steel and Stainless Steel AC TIG – Weld Aluminum with ease AC TIG/Pulse - Minimize warpage and prevent blow through on thin Aluminum AC TIG/MIX – Achieve greater penetration on thick material, while having a more stable arc profile for thinner metals. TIG/Spot – Precisely time welds for repeatable production 2T/4T – 2 touch and 4 touch finger control used for amperage control without a foot pedal AC Frequency Control – Fine tune the arc cone width for precise aluminum welding. Programmable settings – 5 Factory Presets and 15 customizable preset to quickly change between your favorite settings. Flex Head 17 Torch – Adjust your torch head to the perfect torch angle in hard to reach places. Gas Flow Meter – Precise gas flow adjustment Rocker Style Foot Pedal – Infinite amperage adjustment without leg fatigue Square Wave IGBT Inverter – Power source enables welding of materials from Aluminum to Steel This machine features AC and DC TIG welding, Pulse, 2T/4T, AC Frequency Control, Spot Timer, and ARC (Stick) welding. The welder comes with a Flex Head 17 torch, Gas Flow Meter, Rocker Style Foot Pedal, Gas Hose and all consumables needed to get started.

The Eastwood TIG 200 Digital has a duty cycle of 25% at 200 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 200 Amps with a 25% Duty Cycle, within a 10 Minute block of time you can weld for 2 Minutes, 30 Seconds with 7 Minutes, 30 seconds of cooling for the Welder. If the Duty Cycle is exceeded, the Welder will automatically shut off, however the fan will continue running to cool the internal components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the duty cycle you can turn down the Amperage Output control. Safety Always wear an approved welding helmet and welding gloves. Do not use around flammable materials. Do not open machine there are no user serviceable parts inside.
