Professional inverter welding machine FORBY® TIG 200MX AC/DC
This is a modern pulse inverter TIG/MMA 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 wide parameter adjustment help you achieve professional weld quality both in the workshop and in a home garage.
Key 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 connection - for controlling the welding current by foot.
- Overvoltage, overload and overheating protection - for safety and long service life.
The welding machine is an inverter type and uses advanced IGBT technology. The inverter converts the 50Hz/60Hz AC voltage from the mains into DC voltage, which is then transformed back into AC voltage by a high-frequency (20 kHz) converter.
IGBT technology allows efficient adjustment of 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)
LIFT-TIG (DC TIG)
AC TIG ignition with reverse polarity improves arc starting

AC PULSE TIG
Additional functions:
Arc-Break Prevention - HF maintains the arc if it breaks
Short-circuit protection when the tungsten touches the workpiece
Foot pedal control option (5-pin connector)
Control panel and functionality:
The front control panel lets you select the operating mode (HF TIG, Lift TIG, MMA, GAS), 2T/4T, Cold Weld and VRD functions, and precisely set the main parameters: start current, peak current, pulse base current, pulse frequency and width, AC frequency, AC balance, gas pre-flow and post-flow, crater current and more.
- AC FREQUENCY 40-200 Hz - for controlling bead 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 shape (concentrated arc, deep penetration).
AC TIG for aluminium - slightly rounded tungsten tip; adjust the AC balance according to the oxides.
Argon 99.99 % - recommended gas; typical flow 6-10 l/min.
Up/Down Slope and Crater Current help prevent craters at the start and end of the weld.
Main specifications of the welding machine:
The TIG 200MX ACDC welding machine works in both TIG (AC/DC) and MMA modes, has a high 68 V open-circuit voltage for easy arc ignition, and wide current ranges: TIG 10-200 A, MMA 10-180 A. The machine complies with EN 60974-1/10 standards, is powered from a 230 V mains supply and has an IP21S protection class. Duty cycles are good for its class: 200 A at 60 % in TIG mode, 180 A at 60 % in MMA mode, which means stable operation 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 indicates how long the machine can operate without overheating within a 10-minute cycle)
Compact and mobile -Easy to carry and easy to integrate into a welding trolley. Weight approx. 9.2 kg according to technical data.
Robust and durable construction - The powder-coated housing is resistant to scratches, corrosion and intensive daily use.
Clear and functional control panel - Bright digital display, convenient controls for TIG ACDC parameters: AC balance, AC frequency, pulse settings, HF ignition.
Convenient top carrying handle - The machine is lightweight (9.2 kg), so it is easy to carry between workplaces.
Protected electronics areas - Protection against overvoltage, undervoltage, overload and overheating - the electronics are protected from damage and separated from the gas and heat zone.
Efficient cooling and IP21S protection class - Fan cooling and IP21S protection (provides resistance to moisture and household dust).
Suitable for use in dry environments, but not outdoors in the rain.
Heavy-duty 35-50 type connectors - Robust industrial connectors ensure good contact and stable current transfer.
QUICK AND CONVENIENT GAS HOSE CONNECTION
1. The integrated quick gas coupling allows the gas hose to be connected or disconnected easily and quickly. This shortens the machine set-up time and makes moving and transporting it easier.
2. A 3-metre pressure-resistant gas hose is included with a quick coupling on the machine side. The optimal hose length gives more freedom to conveniently position the welding machine and gas cylinder at the workplace.
ROBUST CONNECTORS DESIGNED FOR HIGHER LOADS
Heavy-duty 35-50 type welding cable connectors ensure reliable contact and stable current transfer. Properly connected and locked connectors help reduce contact resistance, connector heating and energy losses at the connection points.
Convenient cable connection in TIG and MMA modes. The large connectors allow welding cables to be firmly attached and easily disconnected when changing 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 machine uses heavy-duty 35-50 type cable connectors - a practical solution for everyday welding work.
