FORBY® TIG 200MX AC/DC welding machine (200A - 60%) (pulse)

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 a wide range of parameter settings help you get professional weld quality in the workshop or in your 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 - easy contactless arc ignition.
• Foot pedal connection - control the welding current with your foot.
• Overvoltage, overload and overheating protection - for safety and a long service life.

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 for better arc starting

Available TIG modes:
DC TIG
DC PULSE TIG
AC TIG (square wave)
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 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 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 % - balances oxide cleaning and penetration for aluminium.
• Pre Flow / Post Flow - gas flow before and after welding.
• Up / Down Slope - smooth start and end of the current.
• Hot Start, Arc Force (MMA) - easier electrode ignition and a more stable arc.

DC TIG - grind the tungsten to a cone shape (focused arc, deep penetration).
AC TIG for aluminium - slightly rounded tungsten tip; adjust the AC balance to the amount of oxide.
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 welding machine specifications:

The TIG 200MX ACDC welding machine works in both TIG (AC/DC) and MMA modes. It 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, runs on 230 V mains power and has an IP21S protection rating. 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 stably 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)
