The PrimeWeld TIG200-D 200-Amp Inverter TIG Welder offers dual-voltage 120/240-volt input power, letting you weld just about anywhere. When you’re ready to add the beauty, strength, and craftsmanship of true TIG welding to your shop, this 200 amp DC TIG and stick arc welder is the most cost-effective way to do it.

Stick Welding Convenience and TIG Quality

This MOSFET-type inverter TIG welder puts out 190 amps when plugged into 240-volt power, enough to weld 7/16-inch steel in a single pass. The stick mode produces 185 amps. When running on 120-volt input, the TIG function makes 145 amps, and the stick side puts out 140 amps.

The lower limit output of 10 amps for either process is mild enough heat to weld on 24-gauge sheet metal. For additional heat control, PrimeWeld includes a foot pedal to avoid overheating the workpiece, a crucial part of welding sheet metal.

Advanced Features For This 200 Amp TIG Welder

Adjustable Postflow: Not only does this 200 amp TIG welder also gives you Stick welding ease of use, but it also includes adjustable postflow for the shielding gas. The TIG200-D sets gas postflow at either 2 seconds or 5 seconds at the flip of a switch. When running low current levels, flip the switch to 2S for 2 seconds of flow, and on high current work flip the 2S/5S switch for 5 seconds of postflow.

Change Processes Quickly: You can choose which welding process you’re running with a simple flip of the switch from MMA to TIG and a quick change of leads.

Advanced Power Source: This MOSFET inverter TIG welder keeps the arc smooth no matter which process you’re running

Overheating and Overcurrent Protection: The PrimeWeld TIG200-D DC TIG welder with stick features modern, proven technology to protect your investment from damage due to overheating or current spikes.

Digital Display: It’s hard enough to work with a helmet and protective gear with smoke, sparks, and lighting changes. A digital readout lets you monitor your current levels quickly, accurately, and efficiently. No more squinting to figure out how hot you’re running

High-Frequency Arc Starts: The TIG200-D features high-frequency no-touch starting to preserve your tungsten electrode and consumables while avoiding contamination of the weld puddle with the electrode material.

Foot Pedal Heat Control: Try to find another 200 amp TIG welder with MOSFET technology, dual-voltage input power, high-frequency arc starts, AND an INCLUDED FOOT PEDAL HEAT CONTROL at this price!

Even if you can find one with all this from another maker, only the PrimeWeld TIG200-D comes with Legendary PrimeWeld Support


PrimeWeld Customer Service delivers knowledgeable PEOPLE who are easy to contact, give great advice, and know what it takes to keep you welding.

  3. Connect the TIG torch connector to the TIG torch terminal and tighten it.
  4. Connect the ground cable connector into the positive terminal and tighten it.
  5. Connect the foot pedal remote lead into the 5pin socket. Or connect the torch switch lead into the 5pin socket.
  6. Connect the gas regulator (not included) to the cylinder and connect the gas line to the regulator.
  7. Carefully open the valve of the gas cylinder. Set the flow to 15-25CFH (7-12LMN).
Selector Switches

tig200d welder selector switch functions

  1. ON/OFF: This switch powers the machine up when switched to the on position and powers the machine down when switched to the off position. NOTE: The On/Off switch is on the back of the TIG200D.
  2. MMA/TIG: Provides selection of TIG or SMAW (Stick) welding modes. Selecting the TIG position provides for TIG welding function. Selecting the MMA position provides for DC SMAW (Stick) welding function.
  3. 2S/5S: Provides control of gas flow after the welding arc is extinguished. Post gas flow prevents contamination of the weld pool during its cool down period from molten state to solid at the weld finish and keeps the tungsten electrode protected from oxidizing atmosphere during the cool down cycle. The post gas flow time will depend on the tungsten size and welding current that is being used. Low current choose 2 seconds, high current choose 5 seconds.
  4. Foot Pedal/Panel Control: Provides the selection of Foot Pedal Control or Panel Control. Selecting the Foot Pedal position when using with foot pedal. Selecting the Panel Control when using with the TIG torch switch.
  5. Welding Current Adjustment Knob: Provides adjustment and control of the main welding unit.
