The machine power supply electrical network request
* Power line voltage profile should for the actual unreliable wave.
* The power line voltage undulation should not surpass 15% of the rated voltage.
WELDING MACHINE MAIN PRINCIPLES
The welding machine obtains the 220V power frequency alternating current through switch
SW101, after the inductance coil filter for the single plane rectification bridge MDQ3504*2
rectification, and has the electric capacity C1-C4 filter to turn the direct current, by way of the
IGBT composition bridge type invertor inversion existing agreement is the 20KHZ alternating
current, passing through the intermediate frequency transformer TI live pressure, and restores the
diode DK.1-DK6 rectification quickly, at last filters by the output reactor LI01 and outputs steadily
the direct-current power supply for the welding.
THE STRUCTURE OF WELDING MACHINE
TIG series product adoption design beauty of plastics shape in front and back front-panel,
the front panel is first half part have a yellow indicator, white indicator, green indictor, weld electric
current and regulate and choose knob, the lower part loads torch connector (electric current output"-
" pole), earth clamp and clipping quick connector(electric current output"+" pole), the torch switch,
behind the plank have power switch, power supply importation fuse and fan cooled, the gas of input
connector, the roof has plastic handle and bottom contain 4 rubber mats .Open the shell you can see
two pieces of control a printing circuit plank, ,and middle has one leading arc board, the scale board
has an outputs electric shock anti- machine, main transformer and radiator.
INSTALLMENT
CONNECT MACHINE AND POWER
Put the welding machine rear panel power line plug connect to the AC220V power plug, the
machine must earth reliably. Forbid strictly using the AC380V power source, otherwise the
consequence is proud.
connect machine and torch
connect machine and earth clamp
OPERATION STEPS
Connect the power first and turn power switch.
To adjust electric current which you need.
Connect the earth clamp and work pieces
When the welding rod burns to leave 1-2 mms ,you need to change the new one
When welding has completed you should clean the surface of machine.
TRANSPORTATION AND STORAGE
The electric welding machine is a common indoor usage equipments, should avoid rain and snow
