Ideal for repetitive tacking on thin sheet materials, it can be set between 1 and 5 pulse cycles or continuous cycle mode, with independently adjustable current and arc cycle time from 1 to 200 ms — ensuring consistent, controlled results every time.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWeld Assist — Intelligent Parameter Setup\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eWeld Assist walks operators through a simple on-screen setup — selecting material type, plate thickness, joint type, and welding position — and automatically configures the optimal welding parameters. It also provides recommendations for electrode size, filler wire, gas flow, groove type, pass profile, and travel speed. Weld Assist supports \u003cstrong\u003epWPS creation\u003c\/strong\u003e for quality-managed environments and is particularly valuable for lower-frequency TIG welding tasks where manual parameter knowledge may be limited.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eAutoCool — Dynamic Cooling Management\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eAutoCool intelligently modulates fan speeds and water cooler run times based on actual welding load and duration, reducing electrical power consumption and operating noise.

Asked Questions — Kemppi Master T 245 ACDC GM AU\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat does GM AU mean on the Kemppi Master T 245 ACDC?\u003c\/strong\u003e GM stands for Generator-compatible and Multi-voltage — the machine runs on standard 240 V mains or from a generator, and also accepts a 110 V low-range input. AU denotes the Australian market version, which includes an Australian mains plug and has the VRD (Voltage Reduction Device) permanently locked on to meet Australian safety standards.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eCan the Kemppi Master T 245 ACDC GM AU weld aluminium?\u003c\/strong\u003e Yes. The AC TIG mode makes the Master T 245 ACDC GM AU fully capable of welding aluminium and aluminium alloys. The Optima AC waveform gives welders additional control over the arc character — allowing selection between sine, square, or Optima AC depending on the alloy and application.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is VRD and why is it locked on in the AU model?\u003c\/strong\u003e VRD stands for Voltage Reduction Device. When active, it reduces the no-load MMA voltage from 50 V to 23 V, significantly reducing the risk of electric shock when the arc is not struck. The AU model has VRD permanently engaged to comply with Australian workplace health and safety regulations — particularly important for welding in confined spaces or on construction sites.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is the minimum generator size for the Master T 245 ACDC GM AU?\u003c\/strong\u003e Kemppi recommends a minimum generator output of \u003cstrong\u003e8 kVA\u003c\/strong\u003e to reliably power the Master T 245 ACDC GM AU at full welding capacity on 240 V input.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is the duty cycle of the Kemppi Master T 245 ACDC GM AU?\u003c\/strong\u003e At maximum rated output of 240 A (on 240 V supply), the machine operates at a 40% duty cycle. At 200 A it delivers 60% duty cycle, and at 170 A it can run continuously at 100% duty cycle — making it well-suited to sustained production TIG welding sessions.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is MAX WeldClean on the Master T 245 ACDC GM AU?\u003c\/strong\u003e MAX WeldClean is a built-in electrolytic cleaning mode that removes oxidation and discolouration from stainless steel welds, making them surface-finished without additional post-processing equipment. It saves time and cost on finishing work in stainless steel, food-grade, and architectural fabrication.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Master T 245 ACDC GM AU and the Master T 355 ACDC?\u003c\/strong\u003e The 245 ACDC GM AU is a single-phase 240 V model designed for portability, site use, and generator operation — ideal where 3-phase power is not available. It delivers up to 240 A TIG output and weighs 19.1 kg. The 355 ACDC requires a 3-phase 400 V supply, delivers up to 350 A, and weighs 21 kg — better suited to fixed workshop environments with higher-output demands.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat control panel options are available for the Master T 245 ACDC GM AU?\u003c\/strong\u003e The power source is sold separately from the control panel. Options include traditional touch-button panels or the full-colour 7\" TFT panel, which offers Weld Assist, 99 memory channels per welding process, and full waveform customisation. The 7\" TFT panel is protected by a 3 mm armour shield plate.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDoes the Master T 245 ACDC GM AU support MMA (stick) welding?\u003c\/strong\u003e Yes. In addition to AC and DC TIG, the machine supports MMA welding up to 180 A, accepting stick electrodes from 1.6 mm to 5 mm in diameter.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eIs the Master T 245 ACDC GM AU compatible with WeldEye?\u003c\/strong\u003e Yes. The machine is compatible with Kemppi's WeldEye cloud-based welding quality management service, enabling digital welding data recording, WPS management, and traceability reporting for quality-controlled applications.\u003c\/p\u003e","brand":"Kemppi","offers":[{"title":"Default Title","offer_id":47845068439703,"sku":"MST245ACDCGMAU","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0301\/8663\/5399\/files\/2157853_18fe8d4f-0650-4b74-9461-39d5104e5b46.webp?v=1780624130","url":"https:\/\/www.weldingsupply.com.au\/products\/kemppi-master-t-245-acdc-gm-au","provider":"QWS - Welding Supply Solutions","version":"1.0","type":"link"}
