At 220–230 V low-range, it delivers up to \u003cstrong\u003e450 A TIG\u003c\/strong\u003e at a 40% duty cycle — maintaining near full performance even on lower-voltage 3-phase supplies. This multi-voltage flexibility is a critical advantage for operations running across multiple sites or international facilities with different 3-phase voltage standards.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eGenerator Compatible — High-Output TIG on Site\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe G designation confirms the Master T 505 ACDC GM AU is rated and tested for generator operation — enabling professional 500 A AC\/DC TIG welding in environments without fixed 3-phase mains infrastructure, including major construction projects, mining and resources sites, shipyard docking areas, and offshore facilities.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eVRD Locked On — Australian Safety Compliance\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe AU model features a \u003cstrong\u003epermanently engaged Voltage Reduction Device (VRD)\u003c\/strong\u003e, reducing the MMA open-circuit voltage to \u003cstrong\u003e23 V\u003c\/strong\u003e when the arc is not struck. This satisfies Australian occupational health and safety regulations for welding in confined spaces, on construction sites, and in any environment where electric shock risk requires mitigation. VRD is factory-set and cannot be disabled.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eMAX WeldClean — Electrolytic Weld Cleaning Built In\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eEvery Master T ACDC model — including the 505 — includes MAX WeldClean as standard. This electrolytic cleaning mode removes oxidation and discolouration from stainless steel welds directly from the welding machine, without the need for separate post-processing equipment. For high-volume stainless fabricators in food, pharmaceutical, architectural, and industrial applications, MAX WeldClean delivers significant time and cost savings on surface finishing.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDeMagnetization Mode\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe DeMagnetization (degaussing) mode eliminates residual magnetic fields in parent material caused by magnetic lifting equipment, magnetic workholding, or proximity to heavy electrical machinery. Residual magnetism degrades arc stability and directional control in TIG welding; eliminating it before welding restores consistent arc behaviour — particularly important on large steel fabrications and assemblies that have been handled extensively through production.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eDouble Pulse TIG\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eDouble Pulse alternates between two pulse cycles to deliver up to \u003cstrong\u003e30% faster welding travel speed\u003c\/strong\u003e and \u003cstrong\u003e20% reduced heat input\u003c\/strong\u003e compared to standard pulsed TIG. This directly reduces distortion on heat-sensitive materials, lowers labour costs on long-seam production welding, and produces a visually superior weld seam — making it particularly effective on stainless steel pipe, aluminium structural fabrications, and precision mechanical components.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eOptima AC Waveform\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe Optima AC waveform is Kemppi's engineered AC TIG arc profile that combines the preferred characteristics of sine and square waveforms into a single, configurable output. Welders can freely select between sine, square, or Optima AC to tune the arc character to the specific aluminium alloy, joint geometry, and surface condition — providing the most refined AC arc control available in the Master T platform.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eMicroTack — Precision Tacking at Any Scale\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eMicroTack delivers fast, controlled tacking in both AC and DC TIG welding with the minimum heat input necessary. Configurable from 1 to 5 pulse cycles or continuous mode, with independently adjustable current and arc cycle time from 1 to 200 ms, MicroTack ensures consistent, repeatable tack weld quality whether the application is thin-sheet aluminium skin panels or heavy structural steel sections.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWeld Assist — Guided Parameter Setup for Every Welder\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eWeld Assist guides operators through on-screen material, thickness, joint type, and welding position selections and automatically sets optimal welding parameters. It also recommends electrode size, filler wire, gas flow, groove type, pass profile, and travel speed — reducing setup errors and improving consistency across multi-operator workshops and shift changes. At 500 A output, accurate parameter setup is critical to avoid weld defects and material damage; Weld Assist removes the guesswork. Full \u003cstrong\u003epWPS (preliminary Welding Procedure Specification)\u003c\/strong\u003e compatibility is included for quality-managed environments.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eAutoCool — Intelligent Cooling Management\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eAutoCool dynamically modulates fan speed and water cooler run times based on the actual welding load and duration. On a 500 A machine operating in a production environment, AutoCool's ability to reduce idle cooling energy and noise during lower-output intervals delivers meaningful efficiency gains across a full working day.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eReliable Arc Ignition at High Output\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe Master T 505 ACDC GM AU features Kemppi's engineered ignition technology with adjustable spark force energy — ensuring clean, reliable arc starts at all output levels, including high-current applications where tungsten electrode condition and arc initiation technique are critical to weld quality.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eBluetooth Wireless Connectivity\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eBuilt-in Bluetooth communication supports optional wireless remote controls, including the \u003cstrong\u003eHR45 wireless hand remote\u003c\/strong\u003e and \u003cstrong\u003eFR45 wireless foot pedal\u003c\/strong\u003e — enabling current adjustment from the torch or foot pedal without returning to the power source. The foot pedal remote is particularly valuable for precision TIG welding where current ramp control during puddle management is required.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eOptional 7\" TFT Control Panel\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe optional full-colour \u003cstrong\u003e7\" TFT control panel\u003c\/strong\u003e, protected by a 3 mm armour shield plate, provides fast parameter setting, full Weld Assist access, and up to \u003cstrong\u003e99 memory channels per welding process\u003c\/strong\u003e — essential for high-throughput workshops running multiple materials, WPS-controlled procedures, and frequent job changeovers.

ACDC indicates the machine supports both AC TIG (for aluminium) and DC TIG (for steel, stainless, titanium, and other metals). GM indicates generator compatibility and multi-voltage input — accepting both standard 3-phase 400 V and 3-phase 220–230 V supplies. AU indicates the Australian market version, with an Australian mains plug and VRD permanently locked on.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum output of the Kemppi Master T 505 ACDC GM AU?\u003c\/strong\u003e On a standard 3-phase 400 V supply, the machine delivers a maximum TIG output of 500 A at a 30% duty cycle. On the 3-phase 220–230 V low-range multi-voltage supply, it delivers up to 450 A TIG at a 40% duty cycle. For MMA welding, the maximum output is 400 A.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eCan the Kemppi Master T 505 ACDC GM AU weld aluminium?\u003c\/strong\u003e Yes. The AC TIG mode and Optima AC waveform make the 505 ACDC GM AU fully capable of welding aluminium and aluminium alloys at up to 500 A — making it one of the highest-output aluminium TIG welders available in the Australian professional market. It is well-suited to heavy aluminium plate, structural sections, and large-format marine or defence fabrications.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eHow heavy is the Kemppi Master T 505 ACDC GM AU?\u003c\/strong\u003e The Master T 505 ACDC GM AU weighs \u003cstrong\u003e57 kg\u003c\/strong\u003e without accessories — significantly heavier than the 355-class Master T models at 21 kg. It is designed to be used with the P45MT 4-wheel transport cart or T25MT 2-wheel cart and is intended for fixed or semi-fixed installation rather than frequent manual relocation.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Master T 505 and the Master T 355?\u003c\/strong\u003e The primary difference is output capacity. The 505 delivers 500 A TIG (vs 350 A for the 355), handles MMA up to 400 A (vs 270 A), and is physically much larger at 57 kg (vs 21 kg). The 505 also includes multi-voltage 3-phase low-range input capability, enabling operation on 220–230 V 3-phase supply at up to 450 A — a feature not available on the 355 ACDC G AU. Both models include the full Master T ACDC feature set including MAX WeldClean and DeMagnetization.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat is MAX WeldClean on the Master T 505 ACDC GM AU?\u003c\/strong\u003e MAX WeldClean is a built-in electrolytic cleaning mode that removes oxidation and discolouration from stainless steel welds using the welding machine itself — without additional post-processing equipment. On a 500 A machine handling large stainless fabrications, MAX WeldClean delivers significant time and cost savings on surface finishing for food grade, pharmaceutical, architectural, and industrial applications.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eIs the Master T 505 ACDC GM AU compatible with WeldEye?\u003c\/strong\u003e Yes. The machine is compatible with Kemppi's WeldEye cloud-based welding quality management platform, enabling digital WPS management, welding data recording, welder qualification tracking, and full project traceability — critical for fabrication to AS\/NZS, ISO, EN, and ASME welding standards.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat control panel options are available for the Master T 505 ACDC GM AU?\u003c\/strong\u003e The power source is sold separately from the control panel. The recommended option for most professional users is the full-colour \u003cstrong\u003e7\" TFT panel\u003c\/strong\u003e with Weld Assist, 99 memory channels per welding process, and full waveform customisation. The 7\" TFT panel is also required to access MAX WeldClean and DeMagnetization modes. Touch-button panel alternatives are also available.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhat wireless remote controls are available for the Master T 505 ACDC GM AU?\u003c\/strong\u003e The machine supports the \u003cstrong\u003eHR45 wireless hand remote\u003c\/strong\u003e for current adjustment from the torch position, and the \u003cstrong\u003eFR45 wireless foot pedal\u003c\/strong\u003e for hands-free current ramp control during precision TIG welding. Both communicate via Bluetooth.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eWhy does the Master T 505 weigh 57 kg when the 355 weighs 21 kg?\u003c\/strong\u003e The 505's 57 kg weight reflects the substantially larger transformer, cooling system, and power electronics required to sustain 500 A AC\/DC TIG output. At 500 A the power handling demands are considerably greater than at 350 A, particularly in AC mode where the machine must generate and control both positive and negative half-cycles of the AC waveform at high current. The larger physical enclosure also accommodates the integrated cooling infrastructure for sustained high-duty-cycle operation.\u003c\/p\u003e","brand":"Kemppi","offers":[{"title":"Default Title","offer_id":47867750383767,"sku":"MST505ACDCGMAU","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0301\/8663\/5399\/files\/11043077.webp?v=1780625918","url":"https:\/\/www.weldingsupply.com.au\/products\/kemppi-master-t-505-acdc-gm-au","provider":"QWS - Welding Supply Solutions","version":"1.0","type":"link"}
