Telwin miminmax 100 - no arc

[Jeremy Ard]

Hi. I have a Telwin mini max 100. When I turn it on I get gas and wire feed. I can hear the transformer working but get no arc. The welder has not been used for about five years.

Can anyone help please?

check all connections even if they look good, when you say you hear the transformer working is it only buzzing when you pull the trigger ? and is it a really loud bad buzzing ? if so it could be the rectifier
