Professional inverter welding machine FORBY® TIG 200MX AC/DC
This is a modern pulse TIG/MMA inverter welding machine for precise welding of stainless steel, mild steel, aluminium, titanium and other non-ferrous metals. AC/DC modes, pulse TIG, HF high-frequency arc ignition and a wide range of parameter settings help you get professional-quality welds in a workshop or a home garage.
Main advantages:
- AC/DC TIG and MMA modes - suitable for steel, stainless steel, aluminium, titanium alloys and more.
- Pulse TIG - ideal for thin sheets and stainless steel.
- HF high-frequency ignition - convenient contactless arc ignition.
- Foot pedal connector - for controlling the welding current by foot.
- Overvoltage, overload and overheating protection - for safety and a long service life.
This is an inverter-type welding machine that uses advanced IGBT technology. The inverter converts the 50Hz/60Hz AC mains voltage into DC voltage, which a high-frequency (20 kHz) converter then turns back into AC voltage.
IGBT technology allows efficient control of the welding parameters, ensures a stable arc and reduces energy losses.
Main features of the machine
TIG modes (DC / AC / PULSE TIG)
Current range:
DC TIG: 10-200 A
AC TIG: 10-200 A
Ignition:
HF high-frequency ignition (AC/DC TIG)

AC PULSE TIG
Additional functions:
Arc-Break Prevention - HF keeps the arc going if it breaks
Short-circuit protection when the tungsten touches the workpiece
Foot pedal control option (5-pin connector)
Control panel and functions:
The front control panel lets you select the operating mode (HF TIG, Lift TIG, MMA, GAS), 2T/4T, Cold Weld and VRD functions, and set the main parameters precisely: start current, peak current, pulse base current, pulse frequency and width, AC frequency, AC balance, pre-flow and post-flow gas, crater current and more.
- AC FREQUENCY 40-200 Hz - controls weld width and penetration.
- AC BALANCE 20-80 % - balance between oxide cleaning and penetration for aluminium.
- Pre Flow / Post Flow - gas flow before and after welding.
- Up / Down Slope - smooth current start and finish.
- Hot Start, Arc Force (MMA) - easier electrode ignition and a more stable arc.
DC TIG - grind the tungsten to a cone (concentrated arc, deep penetration).
AC TIG for aluminium - use a slightly rounded tungsten tip and adjust the AC balance to the amount of oxide.
Argon 99.99 % - the recommended gas, with a typical flow of 6-10 l/min.
Up/Down Slope and Crater Current help prevent craters at the start and end of the weld.
Main welding machine specifications:
The TIG 200MX ACDC welding machine works in both TIG (AC/DC) and MMA modes. Its high 68 V open-circuit voltage makes arc ignition easy, and it has wide current ranges: TIG 10-200 A, MMA 10-180 A. The machine complies with EN 60974-1/10, runs on 230 V mains and has an IP21S protection rating. Its duty cycles are good for its class: 200 A at 60 % in TIG mode and 180 A at 60 % in MMA mode, so it runs steadily at higher currents without overheating.
Current characteristics:
- Current range: 10 A - 200 A
- Voltage at 10 A: 10.4 V
- Voltage at 200 A: 18 V
Duty cycle:
- 60% load: 200 A
- 100% load: 155 A
(the duty cycle shows how long the machine can run without overheating within a 10-minute cycle)
Compact and mobile -Easy to carry and easy to fit on a welding cart. Weighs about 9.2 kg according to the technical data.
Robust and durable construction - The powder-coated housing resists scratches, corrosion and heavy daily use.
Clear and functional control panel - Bright digital display and easy-to-use controls for TIG ACDC parameters: AC/AC balance, AC frequency, pulse settings, HF ignition.
Convenient top carrying handle - The machine is light (9.2 kg), so it is easy to move between workplaces.
Protected electronics zones - Protection against overvoltage, undervoltage, overload and overheating keeps the electronics safe from damage, and they are separated from the gas and heat zone.
Efficient cooling and IP21S protection rating - Fan cooling and IP21S protection (resistance to moisture and household dust).
Suitable for use in dry environments, but not outdoors in the rain.
Heavy-duty 35-50 type connectors - Sturdy industrial connectors ensure good contact and stable current transfer.
QUICK AND CONVENIENT GAS HOSE CONNECTION
1. The built-in quick gas coupling lets you connect or disconnect the gas hose quickly and easily. This shortens setup time and makes the machine easier to move and transport.
2. A 3-metre pressure-resistant gas hose is included with a quick coupling on the machine side. The hose length gives you more freedom to position the welding machine and the gas cylinder at the workplace.
STURDY CONNECTORS BUILT FOR HIGHER LOADS
Heavy-duty 35-50 type welding cable connectors ensure reliable contact and stable current transfer. When connected and locked correctly, they help reduce contact resistance, connector heating and energy losses at the connection points.
Convenient cable connection in TIG and MMA modes. The heavy-duty connectors let you attach the welding cables securely and remove them easily when changing the operating mode or preparing the machine for transport or storage.
FORBY welding equipment focuses on quality, durability and ease of use, which is why the FORBY® TIG 200MX AC/DC uses heavy-duty 35-50 type cable connectors - a practical solution for everyday welding work.
