Introduction 

The R-Tech TIG200DV is a member of our field acclaimed family of welding products. 

Premium features include:

1. Inverter power source – more efficient to operate, provides smoother weld characteristics.

2. Use either 110V or 240V input, machine automatically sense voltage input.

3. Full Featured Pulse welding in DC Tig welding mode

4. HF Arc start – Easy arc striking and prolonged tungsten life

5. Slope up / slope down

6. Remote foot pedal option

7. Digital amp meter

8.

Industrial 60% Duty cycle at maximum amps @ 40C

Recommended Processes 

The R-Tech TIG200DV is recommended for the Tig welding processes within its output capacity of 

200 Amps (240V) and 140 Amps (110V) 

Equipment Limitations 

The R-Tech TIG200DV is protected from overloads beyond the output ratings and duty cycle as per 

machine specifications with thermostat protection of the output coils and rectifiers. 

Welding Capability – Duty Cycle 

The R-Tech TIG200DV is rated at 60% duty cycle on a ten minute basis. If the duty cycle is 

exceeded a thermal protector will shut machine off until the machine cools.
