The Parweld XTT 353P AC/DC is a 3 phase TIG welding inverter with full TIG welding parameter adjustment.

Square wave AC output and power pulsing maximises productivity whilst allowing the user to fine tune heat output.


The XTT 353 P AC/DC is an industrial machine and is generator friendly, coping with ±15% voltage fluctuations.

In TIG mode the Parweld XTT 353P can weld materials up to 9mm in thickness.

The XTT can also be used in MMA mode.


The XTT 353 air cooled package supplied with a Parweld PRO Grip 26 torch with ergonomic handle for increased welder comfort.  A knuckle joint improves cable flexibility and increased dexterity.

Water cooled package supplied with a Parweld PRO Grip 18 water cooled torch also with ergonomic handle.


A high frequency start circuit makes for easy and uncontaminated arc starting, increasing Tungsten electrode life.

Trigger latching allows the user to release the trigger during long welds to improve comfort.


Simple adjustability.

Buttons to select between MMA and TIG modes, AC or DC as well as selecting 2T, 4T, HF start or lift TIG.

2 Arrow buttons allow the user to scroll through pre flow, start current, up slope, main current, background current, pulse frequency, pulse balance, down slope, final current and post flow.  Once the LED indicates the parameter to set, simply turn the middle dial to change settings.  (See product video tab above for demonstration – video shows the single phase XTT 202P but controls remain the same)
