The Eastwood TIG 200 welder with High-Frequency Inverter Technology is capable of welding thin or heavy gauge steel and aluminium with precision and ease. The Voltage self-sensing circuitry automatically detects a power source range of 110 to 240 Volts and delivers from 10 up to 200 Amps of AC or DC current at super-high frequency with the added advantage of a light weight unit. The specially engineered 200-amp Eastwood TIG Welder offers affordable, professional-quality TIG welding on aluminium, stainless or steel (sheet, tube or bar stock), and precise welding of thinner-gauge materials up to 1/4\" thick. The included foot pedal provides the operator with the precise Amperage control required when welding. A high frequency start feature guarantees an instant arc strike with no tungsten contamination. Premium Welding Power Backed by Experts With its updated versatile design, powerful welding capabilities and guaranteed quality, this may be the last TIG you buy. It comes with a Flex Head WP17 style torch that uses common consumables and allows you to get into tighter spots. The included 240V/120V adapter cord simplifies the process of switching between voltage. The 60% duty cycle keeps you welding until the job is finished.

Duty Cycle The Rated Duty Cycle refers to the amount of welding that can be done within an amount of time. The Eastwood TIG 200 has a duty cycle of 60% at 190 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 190 Amps with a 60% Duty Cycle, within a 10 Minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the welder. To increase the Duty Cycle you can turn down the Amperage Output control. Going above 190 Amps will yield a lower duty cycle.
