Perfect Welding


The TransTig is a completely digitised TIG DC power source. Alongside the different power categories from 80 to 500 A, the devices also vary in their mobility – from the mobile, portable device to the stationary, high-power complete system. However, they all have one thing in common – an extremely robust design for a long service life and an exceptionally self-explanatory operating concept.
Please choose your desired product.

When developing the TransTig 170/210, our focus was entirely on the benefit for our customers. What is needed is absolutely clear: a perfect, stable arc. The higher operating frequency of the inverter technology makes this stability possible - due to precise control. Other benefits of this optimized process technology are maximum efficiency in the duty cycle, the output power and the mains voltage supply. Last but not least, this increased efficiency also makes welding more enjoyable!

With TAC, one spot is all it takes for tacking, because the pulsed arc sets the two weld pools in motion, making them jump together in next to no time, to make one single weld-pool. The TAC function is also very useful when welding light-gauge sheets without filler metal.

HF ignition

The touchless and gentle high-frequency ignition is the easiest option for igniting the arc.

Touchdown ignition

Touchdown ignition can be used in particular for sensitive application areas. This allows electromagnetic interference, which can occur during HF ignition, to be avoided.

Efficient TIG welding

 with resonant inverter technology

40% duty cycle

Weld for four minutes without a break at 170 or 210 amperes. On average, weld for one minute longer than the competition.

30% mains voltage tolerance at maximum output power

The inverter technology can compensate for voltage fluctuations or an input voltage that is too low, so that the maximum output power is always supplied. A huge advantage, especially in poorly protected grids!

96 V  – 265 V mains voltage supply

The high bandwidth of the power supply makes the TransTig 170/210 compatible with almost any grid – from every part of the world. A real multivoltage device!

The TransTig 170/210

The digital resonant intelligence reacts optimally to voltage fluctuations, thus ensuring an absolutely stable arc.

Filter as standard

The vast majority of our devices come with a reusable dust/dirt filter fitted that ensures the power components inside the devices remain free of dirt.


FPP - Fronius Power Plug

With the help of a watertight, lockable connector on the back of the power source, the mains cable or mains plug can be changed quickly and easily depending on the place of use.

Robust plastic housing and function carrier

The function carrier is the central element in the design of the power source. It keeps all the components in place. Like the housing, it is made of durable plastic and tested for mechanical loads that far exceed the standard. The carrier provides for the ultimate in durability, while at the same time maintaining a low weight.


TMC - TIG Multi Connector

The universal connection for system components, such as welding torches with special functions (Up/Down, potentiometers) or remote controls, gives the user cross-product advantages.

The operating concept

(1) Knob and Push button

to set the most important welding parameters on the function curve

(2) Gas-test button

to check the gas flow and purge the hosepack after a long period of downtime

(3) Setting button

for welding processes, 2-step, 4-step, and electrode mode

(4) Welding process status indicator

or 2-step, 4-step, and special 4-step mode

(5) Status indicator

remote control mode, electrode overload, CEL mode, Trigger Mode Off, HF, TAC, pulse and spot welding mode



400 V protective circuit

The 400 V protective circuit prevents damage when the device is connected to a power supply that is too high.

Time-Shut-Down/Standby mode

After a defined period of time, the power module switches off and enters standby mode. This mode reduces energy consumption considerably!

PFC – Power Factor Correction

The Power Factor Correction ensures sinusoidal current consumption, making effective use of the available power – only as much power is drawn from the mains as necessary. In addition to energy savings, this results in longer grid leads, improved generator compatibility, and higher welding currents – without tripping the circuit breaker.

Low power consumption

Thanks to an improved power module design and Power Factor Correction technology, the TransTig 170/210 uses up to 40% less input power than comparable competitor devices – with the same output power.
