CO₂ 100% for welding carbon steels, Ar 80% + CO₂ 20% mixture for low-alloy steels (provides better arc and less spatter). ► FLUX welding with self-shielded wire (without gas). - Ideal for outdoor work where wind could blow away shielding gas. ► LIFT TIG TIG welding with touch ignition (Lift TIG). - Suitable for precise welding of stainless steel and thin sheets. ► \"2T\" This refers to the operating mode of the MIG\/TIG torch button (2-touch mode or 2T mode). - 2T (Two Touch \/ 2-stroke) Press the button → the arc ignites. Release the button → the arc extinguishes. - Commonly used for welding short seams or spot welding. ⚡ Crossed spring This symbol indicates the inductance function used in MIG\/MAG welding. Higher inductance → softer arc, less spatter (good for thin sheets). Lower inductance → harder arc, better penetration (for thick materials). arc active only while holding the MIG\/TIG button. ⚡️ HOT START temporarily increases the welding current above the set value at arc ignition to prevent the electrode from sticking to the material, making electrode ignition easier. ⚡️ ANTI STICK reduces voltage and welding current if the electrode sticks to the material, helping to detach the electrode more easily. ⚡️ ARC FORCE stabilizes the arc regardless of its length by regulating the arc dynamics. At the highest ARC FORCE setting, it is possible to \"push the electrode into the molten metal pool and burn through the material.\" In this model, ARC FORCE is adjusted automatically. Operating at the maximum current of 250A requires protection of at least 20A. The device efficiency is as high as 60%. The small size of the device makes it easy to transport and convenient for welding with the device suspended on the arm. - BLACK 37417 4 IN 1 LCD welder - Ground cable - Welding cable MB 3M - Welding mask - Hammer with brush - Original packaging - Polish manual\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIt features an LCD display that shows the welding current, which can be smoothly adjusted using a knob.\u003c\/li\u003e\n\u003cli\u003eThe IGBT transistor combines the advantages of two types of transistors: the easy control of field-effect transistors and the high breakdown voltage and switching speed of bipolar transistors.\u003c\/li\u003e\n\u003cli\u003eRequires a wire feeder.\u003c\/li\u003e\n\u003cli\u003eCan use shielding gases:\u003c\/li\u003e\n\u003cli\u003eAn alternative to MIG, using special flux-cored wire (e.g., 0.8 mm, 0.9 mm).\u003c\/li\u003e\n\u003cli\u003estandard mode:\u003c\/li\u003e\n\u003cli\u003eIn normal MIG, the welder allows adjusting inductance, which affects the \"softness\" of the arc and the amount of spatter:\u003c\/li\u003e\n\u003cli\u003eA crossed spring means that inductance adjustment is disabled or unavailable in the given mode (e.g., MMA or FLUX).\u003c\/li\u003e\n\u003cli\u003e► Summary:\u003c\/li\u003e\n\u003cli\u003eSymbol Meaning Applies to \"2T\" mode: Two-stroke mode\u003c\/li\u003e\n\u003cli\u003eCrossed spring: Inductance adjustment disabled for MIG\/MAG (when function inactive).\u003c\/li\u003e\n\u003cli\u003eBUILT-IN FUNCTIONS:\u003c\/li\u003e\n\u003cli\u003eLower settings produce a soft arc with less penetration, while higher settings increase penetration and allow short arc welding.\u003c\/li\u003e\n\u003cli\u003eThe welder includes a cooling fan for electronic circuits and other components (\"Turbo FAN\" function) and a thermal sensor to protect the device from overheating.\u003c\/li\u003e\n\u003cli\u003eIt operates with a current range from 20 to 250A, allowing welding with electrodes from 2mm to 4mm in diameter.\u003c\/li\u003e\n\u003cli\u003eWelding with 2mm electrodes is possible using a C-class 16A time-delay fuse.\u003c\/li\u003e\n\u003cli\u003eThanks to a large fan in the compact welder housing, airflow is increased, lowering the transistor temperature.\u003c\/li\u003e\n\u003cli\u003eWelding current can be quickly adjusted between 20 and 250A by turning a single potentiometer.\u003c\/li\u003e\n\u003cli\u003eWELDER PARAMETERS:\u003c\/li\u003e\n\u003cli\u003ePower supply: 230V \/ 50Hz\u003c\/li\u003e\n\u003cli\u003eWelding current range: 20-250A\u003c\/li\u003e\n\u003cli\u003eElectrode diameter range: 2\u003c\/li\u003e\n\u003cli\u003e4.0 mm\u003c\/li\u003e\n\u003cli\u003ePower consumption: 6.5kVA\u003c\/li\u003e\n\u003cli\u003eRated welding current: 250A\u003c\/li\u003e\n\u003cli\u003eRated duty cycle: 60%\u003c\/li\u003e\n\u003cli\u003eElectrical network protection: minimum 16A\u003c\/li\u003e\n\u003cli\u003ePower at 100% duty cycle: 175A\u003c\/li\u003e\n\u003cli\u003ePower at 60% duty cycle: 250A\u003c\/li\u003e\n\u003cli\u003eInsulation class: IP21S\u003c\/li\u003e\n\u003cli\u003eWelder weight: 6 kg\u003c\/li\u003e\n\u003cli\u003eEQUIPMENT:\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eRequires a TIG torch with valve and argon cylinder (not included).\u003c\/li\u003e\u003c\/ul\u003e","brand":"Blacktools","offers":[{"title":"Default Title","offer_id":56419057140044,"sku":"37417","price":352.08,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/1684\/5388\/files\/7213efce6bfcafc51ac110e308756be1.png?v=1767531727","url":"https:\/\/ostuklikk.ee\/en\/products\/semi-automatic-welding-machine-20-250a-mma-mig-mag","provider":"OstuklikkB2B\/B2C","version":"1.0","type":"link"}
