Inverter welder TIG AC/DC Lincoln Electric Aspect 200

The TIG AC DC ASPECT 200 welder is a single-phase AC/DC power source with a weight of 23 kg, manufactured by Lincoln Electric. This welder is designed for TIG AC/DC and MMA welding, allowing operation with a maximum current of 130A at 100% duty cycle and 200A at 35% duty cycle. The machine is constructed with an IP23 protection class and features the reliable True Heavy Duty design, which provides robust protection for the machine's electronic components through a sealed enclosure. This significantly enhances the durability of the device and extends its service life.

The TIG ASPECT 200 welder features a clear digital display and is equipped with an intuitive and easy-to-use panel. Additionally, it allows for the storage of 9 work programs, greatly facilitating operation for users. A significant advantage of the device is its innovative solution that enables parameter adjustments directly from the welding torch, enhancing user comfort and ensuring a quick and stable welding arc. The welder also boasts low energy consumption due to its single-phase “buck-boost” converter, resulting in lower operating costs compared to devices from other brands. Furthermore, the machine is compatible with generator sets, making it an ideal solution for field applications.

The ASPECT® 200 device allows you to work in Boost mode, which allows you to power the machine from an extension cord up to 100m long and with a cable diameter of 4mm2 and provides more output current with the same input current. The welder also has modes - Green Mode (after 10 minutes without welding puts the device into standby mode) and Idle Mode (<15W After 30 minutes without welding puts the device into sleep mode), which reduce energy consumption and reduce the amount of dirt, eliminating the risk of it being pulled into the machine.

The ASPECT® 200 welder allows for polarity reversal, enabling both direct current (DC) and alternating current (AC) welding. It is equipped with a range of additional TIG functions, making it an excellent choice for even the most demanding applications—especially well-suited for aluminum welding. The TIG functions include:

●        TIG HF: A method of arc ignition that occurs without the electrode touching the workpiece. The HF function remains active for 3 seconds - if the arc is not initiated within this period, the start sequence must be restarted.

●        TIG Lift: a method of striking the welding arc by first touching the electrode to the welded material, the purpose of which is to initiate a low-intensity short-circuit current flow. Then, by tearing the electrode from the welded material, the TIG arc is ignited.

●        2-stroke (2T) and 4-stroke (4T) – optionally 2-stroke (2S) and 4-stroke (4S) with restart: thanks to these modes during welding (after setting the time and the second welding current), we have the possibility of gently decreasing from the main current to the current level set earlier (e.g. to avoid overheating the material).

●        Spot TIG – spot welding function, which is dedicated to joining and welding thin materials.

●        Bi-level (only for 4-stroke 4T): this function causes a rapid (faster than in the 4S-restart function) drop in current value (to the second current, which was set in the menu) to prevent overheating of the welded material. It is possible to return to the main current - these sequences are performed with a quick click,

●        TIG PULS (Pulsed current welding): is possible in the range of 1-2000 Hz for DC mode and 1-100 Hz for AC mode. This function protects the base material from overheating and prevents insufficient fusion at too low a current.

●        Changing the current frequency: frequency adjustment is possible in AC mode in the range of 40-400 Hz. Higher frequency provides better penetration, but causes higher noise level.

●     Balance or Auto-Balance: these parameters are used to clean the aluminum surface from oxides. The Auto Balance function is especially helpful for less experienced users, as it automatically selects the ratio (proportions) of cleaning to fusion.

●        Offset (Negative/Positive): adjusting this parameter allows you to precisely tune and control the amount of current consumed during DC+ cleaning and DC- welding.

●        Waveform selection (for AC): the waveform can be adjusted, which allows the welding arc pressure to be optimized.

●        Adjustment of the diameter and type of tungsten electrode: this function allows the best arc ignition parameters to be obtained.

Application of the Lincoln Electric Aspect 200 welder

In addition to TIG AC/DC welding, the ASPECT® 200 also enables manual welding with coated electrodes (MMA). For MMA welding, special operating modes are available, the selection of which depends on the electrodes used: Crisp mode is designed for welding with cellulose electrodes, as it allows for better penetration, while Soft mode is dedicated to welding with rutile and basic electrodes. In addition, in MMA mode, the ASPECT® 200 offers the following functions:

●        Hot Start: this function improves the ignition properties and causes better fusion of the base material in the initial phase.

●        Anti-Stick: in the event of an electrode short circuit, it makes it easier to detach it from the material by reducing the current value.

●        Arc Force: automatic function that momentarily increases the welding current to prevent the electrode from sticking. It facilitates the welding process.

The ASPECT® 200 AC/DC TIG welder is manufactured in Poland and comes with a 3-year warranty. It is possible to expand the device with a CoolARC24 cooler and a Cart24 cart.
