INFIBULATE OF TUNGSTEN ELECTRODE

(1)TUNGSTEN ELECTRODES TOUCH THE BASE METERIALS DIRECTLY

(2)TUNGSTEN ELECTRODES

 IS MELTING

(1)USE HF (HIGH FREQUENCY)PRODUCE ARC

(2)LOE DONE CURRENT OR INCREASE THE DIAMETER OF ELECTRIDES

(3)CHANGE THE ELECTRODES WITH CRACKS

BAD EFFECTS OF THE PROTECTION OF GAS

THE PURITY OF ARGON IS NOT ENOUGH

(1)UES 99.99%PURITY ARGON

(2)MAKE SURE HAVE ENOUGH TIME FOR ANTICIPATE SENDING AND HYSTERESIS CUTTING THE GAS

(3)DO THE PREWELDING CLEANING WORK

(4)MAKE SURE THE LOW RATE IS CORRECT

(5)ENLARGE THE SIZE OF NOZZLE OR ENLARGE THE LENGTH OF ELECTRODES OUTSIDE THE NOZZLE

UN-STABLE OF ARC

(1)GREASY DIRT ON THE BASE METERIAL

(2)TUNGSTEN ELECTRODES POLLUTION

(3)THE DIA OE ELECTRODES ARE TOO BIG

(4)THE LENGTH OF ARC IS TOO LONG

(5)THE GRINDING OF TOP OF ELECTRODES IS BAD

(1)DO THE PREWELDING CLEANING WORK

(2)DELET THE POLLUTION PART OF ELECTRODES

(3)CHOOSE THE CORRECT  SIZE OF ELECTRODES AND TUNGSTEN ELECTRODES CUP

(4)ADJUST THE DISTANGE OF NOZZLE

(5)GRINDING THE TOP OF ELECTRODES AGAIN(MAKE SURE THE ANGLE IS CURRECT)

TUNGSTEN ELECTRODES TRICKLE

(1)CURRENT IS TOO LARGE

(2)THE GRINDING PART IS TOO LONG ,THE ANGLE IS TOO SMALL

(3)CHOOSEN THE WRONG ELECTRODES

(1)ADJUST THE CURRENT

(2)GAINGDING THE TOP AHAIN

(3)CHOOSE THE RIGHT ELECTRODES ACCORDING TO THE BASE METERIALS

DISSIPATION OF ELECTRODES

(1)OXIDIZE OF ELECTRODES

(2)THE POLARITY IS REVERSED

(1)CLEANING NOZZLE.REDUCE THE DISTANCE OF NOZZLE,ENLARGE THE FLOW RATE

(2)MAKE SUER THE POLARITY IS NOT  REVERSED

(3)ENLARGE THE DIA OF ELECTRODES

(4)ENLARGR THE TOP OF ELECTRODES

(5)GRINDING THE TOP ELECTRODES,MAKE SURE THERE ARE ENOUGH TIME TO HYSTERESIS CUTTING THE GAS
