Features

Red Dot Design Award: Product Design 2020

MasterTig TIG welding machine has been awarded with the Red Dot Award: Product Design 2020. MasterTig is a TIG welding machine that is very intuitive, user-centered, serves the needs of welders, and sets up a new benchmark for any upcoming products. Red Dot Award is one of the most prestigious design awards in the world, and the most sought-after marks of quality for good design internationally.

Double Pulse

Double Pulse combines alternative pulse cycles for 30% faster welding speed and 20% reduced heat input. Lowering distortion levels and weld costs, Double Pulse is ideal for DC hand welding and mechanized applications and offers superb weld seam appearance.

Optima AC

Optima AC is a customized AC TIG waveform that combines the best of the traditional sine and square waveforms – and adds a touch of magic for the optimal AC welding experience. Depending on the application, you’re free to choose either sine, square, or the quiet one: Optima AC.

MicroTack

MicroTack offers fast and accurate tacking with minimum heat input in both DC and AC TIG welding. Ideal for multiple, repetitive tacking on thin sheet applications, where a consistent and controlled appearance is paramount. MicroTack can be set between 1 to 5 repeat pulse cycles or continuous cycle mode. The welding current level is set independently and the arc cycle time selected between 1 to 200 ms.

iTec

iTEC is engineered ignition technology for reliable arc starts. Particularly useful with long torch extensions for site welding or precise thin materials and low current applications, you can set the variable spark force energy.

Auto Pulse

Easy and convenient, the only value to adjust is the welding current itself. Auto Pulse is ideal for applications in DC current.

AutoCool

Dynamic gas and water cooling ensure optimal temperature control and power efficiency. Depending on the welding power level and duration, the power source cooling fans moderate airflow and cooler motor run times between 15 seconds and 4 minutes, reducing electrical power consumption and localized noise levels. MasterTig 535 ACDC also includes an LED water level indicator.

UI control panels

Choose either traditional touch button control panels or the full color 7’’ TFT control panel. Protected by a 3mm armor shield plate, the 7’’ TFT control panel is both impact and scratch-resistant, allows fast and accurate parameter setting with WeldAssist, and offers 99 memory channels per process to save the best parameter or WPS values. MasterTig 535 ACDC includes the MTP35X panel as standard.

Weld Assist

Follow simple on-screen steps, selecting material, thickness, joint type, and position, and Weld Assist sets the right parameters for easy and productive welding. It also gives recommendations for electrode size, filler wire, gas flow, groove type, pass profile, and travel speed. Perfect for pWPS creation.

Personalize

Upload your company logo or favorite image as a screensaver to personalize your MasterTig.

Impact bridge

MasterTig is designed and constructed from strong, energy-absorbing, recyclable plastics, incorporating impact bridge structures that better protect the power source from the everyday knocks of welding life. MasterTig 535 ACDC is fitted with metal side plates.

PivotSafe

MasterTig transport units feature floor-level cylinder loading, removing the need for heavy lifting. The larger 4 wheel transport units integrate an innovative pivoting cylinder plate, for easier and safe cylinder loading.

Wireless remotes

Improve worksite safety by using wireless remotes. Select either hand or foot pedal modules and enjoy wireless power control from a distance of up to 15 or even 100 meters, depending on the worksite.

Torch parts storage

Quickly access frequently used TIG torch parts from the convenient, handle mounted-storage tray. Feature not included to MasterTig 535 ACDC.

Weld time clock

Ideal for total weld cycle measurement and job data records, MasterTig's weld clock is simple and fast to reset, allowing you to record and compare welding times between jobs.

Quick access to product information

MasterTig is equipped with a unique and scannable QR code. It enables easy access to all the relevant information such as product number, serial number, technical specifications, ordering codes, consumables, user manuals, websites, and local dealers or workshops’ contact information. All the information can be found with a single mobile scan.
