5. ars by wearing hearing protection Warning This unit requires proper grounding About your AlphaTig 200X This welder adopts rectifiers designed with advanced inverter technology The introduction of inverter TIG welders derives from inverter power theory and devices The inverter TIG welding power uses high power IGBTs to turn the working frequency of 50 60Hz to high frequency 20KHz or higher Then voltage is reduced and current is regulated A powerful DC power source can be produced by using the pulse width modulation PWM technology The size and weight of inverter welders are reduced remarkably while the efficiency is increased by 30 compared to older styled transformer based welders This product is a multi purpose unit composed of DC pulse TIG welder and AC pulse TIG welder and DC Stick welder MMA This welder allows you the versatility of welding various types of metal including aluminum Warning This unit has a High Frequency start This can interfere with some sensitive electronic components so care should be taken when in close proximity to such devises Parameters Alpha TIG200X Parameter Power voltage Iphase ACI10V 15 Iphase AC220V 15 Frequency Hz 50 60 50 60 Rated Input Current A TIG 37 4 TIG 28 MMA 58 2 MMA 422 Output Current Regulation TIG 10 150 TIG 10 200 MMA 30 145 MMA 30 195 No load Voltage V 50 80
6. h a clean sine wave is recommended for this welder If the welding machine exceeds the standard duty cycle it will go into a protective state and shut down which indicates it has exceeded the duty cycle Excessive heating triggers the temperature control switch and shuts he welding process off Under such circumstances do not turn off the power let the cooling fan continue running to cool down the unit When the temperature drops to the standard range turn the welder off and turn it back on to continue welding 12 WELDS 3 YEAR WARRANTY new AHP welders shall be warrantied to the original owner for a period to extend for 3 years from date of purchase against breakage malfunction or other unit failure resulting from manufacture defect The faulty unit will either be repaired or an exchange will be made for a new or factory reconditioned unit at AHP Welds discretion The customer must contact the technical support team to review unit failure so that the warranty claim can be established Items such as electrodes contact tips nozzles cups shields liners etc considered to be consumable items are NOT covered under warranty Torches foot pedals and spool guns are warrantied for a period of 6 months Additionally certain items such as torches foot pedals and easily serviced parts may be individually exchanged without returning the entire unit assembly should a failure with these items occur at AHP Welds discretion AHP Welds
7. lding operation in an environment with strong winds or airflow should be avoided 2 Essentials for safety This welder has been equipped with over voltage over current and overheat protection circuits When the grid voltage output current and machine temperature surpass the set standards the machine will stop automatically But excessive use for example when the voltage is too high can still lead to the failure of the welder Good ventilation The vents on the welder must be kept clear of all obstructions to allow for good airflow through the unit Keep at least 12 inches clear around the unit No overload Operators should remember that maximum welding amps relative to the duty cycle be observed at all times and welding amps should never exceed the maximum duty cycle Over cycling will shorten the life of the welder No over voltage Power voltage is shown in the main performance parameter table In general the voltage auto compensation circuit in the welder will ensure the welding current remain within the permissible range If power voltage surpasses the permissible value the welder will suffer damage Operators need to be aware of this and take preventative measures On the back of the welder there is a grounding screw with a grounding mark The shell of the welder should be grounded securely with a grounding rod driven into the ground when using a with a clean power generator Only a clean Auto Voltage Regulated generator wit
