Hi guys and ladies would like some help with this little baby,just brought this welder second hand started to use it on setting 1 yep fine gone to setting 2 blew the fuses,6fuses later still scratching my head fuses seem to blow on every setting apart from no1 any body know the reason why/and how do i fix it.

Thanks

u dont say what amperage fuses are blowing , either in the welder or the supply plug more details needed

 

[the snooper]

main transformer windings a possibility ?
does the fuse blow regardless of whether you operate the trigger ?

 

[madkayaker]

how big is the welder and which fuse is blowing? and how big is the fuse?

yep thanks for replying its a 240v domestic supply using the std 13 amp fuse,you switch it to the no1 setting and you can weld, switch to number2 touch the trigger to get the wire rolling it either blows the fuse or trips out the main fuse box as with setting 3,4,5,6.

fuse only blows when switching to no2,3,4,5,6, setting on the main dial no1 you can weld light gauge steel as soon as you press the trigger to get the wire rolling in position 2 fuse blows.

its a 180 on a 240v domestic 13amp plug fitted with a 13amp fuse only blows in position2,3,4,5,6 as soon as you touch the trigger to get the wire rolling.

That does sound very weird. Transformer shorts are rare but do happen sometimes - it would account for the trouble, and a bit of investigation with a meter might validate if that is the trouble.

The only other thing I can think of would be a fault in the power adjustment switch wiring or if some of the wires were shorting together. The switches control which transformer tappings are used.

Guess there's no possibility of just sending it back?

open it up (unplugged) nd measure the resistance of the main transformer and record the results for the different settings if the resistance is to low than the current is to high
