1. Lub tshuab vuam tsis ua haujlwm thaum ko taw pedal nyuaj siab, lub zog taw qhia lub teeb tsis teeb:
a. Xyuas seb lub hwj huam mov voltage yog li cas; xyuas seb qhov kev tswj hwm zoo li cas.
b. Xyuas seb tus ko taw hloov kev sib cuag, AC contactor hu, thiab kais hloov pauv hloov tau zoo lossis raug hlawv.
2. Lub zog taw qhia lub teeb ci ntsa iab, workpiece raug nias tab sis vuam tsis ua haujlwm:
a. Xyuas seb lub ko taw pedal taug kev yog ua tiav thiab yog tias lub ko taw hloov tau ua rau kev sib cuag zoo.
b. Xyuas seb lub siab qws caij nplooj ntoos hlav ntsia hlau puas raug kho.
3. Kev npaj txhij txog spatter tshwm sim thaum vuam:
a. Xyuas seb cov electrode taub yog oxidized hnyav heev.
b. Xyuas seb lub workpiece puas hnyav heev thiab muaj kev sib cuag tsis zoo.
c. Xyuas seb qhov hloov pauv tau teeb tsa siab dhau lawm.
d. Xyuas seb lub electrode siab tsawg dhau lawm thiab yog tias qhov kev pab cuam vuam yog lawm.
4. Qhov hnyav weld indentation nrog cov khoom extruded:
a. Xyuas seb qhov tam sim no siab dhau lawm.
b. Xyuas seb lub workpiece tsis sib xws.
c. Xyuas seb lub electrode siab dhau lawm thiab yog tias cov electrode tip puab thiab cross-section yog tsim nyog.
5. Tsis txaus weld lub zog:
a. Xyuas seb lub electrode siab tsawg dhau lawm thiab yog tias tus pas nrig electrode tau ruaj khov.
b. Xyuas seb lub zog vuam yog tsawg dhau thiab yog tias lub tshuab ua haujlwm hnyav heev, ua rau tsis zoo weld kev sib cuag.
c. Tshawb xyuas cov oxide ntau dhau ntawm lub taub hau electrode thiab electrode pas nrig, thiab nruab nrab ntawm cov pas nrig electrode thiab electrode caj npab.
d. Xyuas seb lub electrode taub hau cross-section tau nce vim hnav, ua rau txo vuam zog.
e. Tshawb xyuas qhov hnyav oxidation ntawm electrode thiab tooj liab hloov tau yooj yim connector mating nto.
6. Qhov txawv txav AC contactor suab nrov thaum vuam:
a. Xyuas seb AC contactor lub input voltage qis dua nws tus kheej tawm voltage ntawm 300 volts thaum vuam.
b. Xyuas seb cov khoom siv hluav taws xob puas yog nyias los yog ntev dhau lawm, ua rau muaj hluav taws xob ntau dhau.
c. Xyuas seb qhov hluav taws xob hluav taws xob tseem ceeb tsawg dhau, tiv thaiv kev ua haujlwm ib txwm muaj.
d. Xyuas seb lub ntsiab transformer luv luv -circuited, ua rau tam sim no ntau dhau.
7. Overheating ntawm lub vuam tshuab:
a. Xyuas seb qhov rwb thaiv tsev tsis zoo ntawm cov khoom siv hluav taws xob thiab lub tshuab lub cev tsis zoo, ua rau ib feem luv luv Circuit Court.
b. Tshawb xyuas seb qhov dej nkag hauv dej, qhov dej ntws, thiab dej qhov dej kub yog qhov tsim nyog. Tshawb xyuas seb puas muaj av lossis thaiv hauv cov dej, uas tuaj yeem ua rau overheating ntawm electrode caj npab, electrode pas nrig, thiab lub taub hau electrode vim tsis txias.
c. Xyuas seb qhov chaw sib cuag ntawm cov tooj liab hloov tau yooj yim connector, electrode caj npab, electrode pas nrig, thiab electrode taub hau yog oxidized heev, ua rau muaj kev tiv thaiv thiab overheating hnyav.
d. Xyuas seb tus ntoo khaub lig-sectional cheeb tsam ntawm lub taub hau electrode tau nce ntau dhau vim hnav, ua rau lub vuam tshuab dhau los thiab kub dhau.
e. Xyuas yog tias lub vuam thickness thiab lub voj voog ua haujlwm dhau qhov kev txwv, ua rau lub tshuab vuam dhau thiab overheat.
