Thanks will try manually pushing contactor if that fires up must be dodgy contactorFrom what I can see online, this Hobart is a traditional transformer-based MIG welder.
When the torch trigger is pressed, three things should happen:
- main contactor closes
- gas valve opens
- wirefeed motor turns
Do any of these actions happen?
The main contactor often has a manual operating button. If the contactor is not operating on demand, then pressing the manual button ( e.g. with an insulated screwdriver ) may help to diagnose the fault.
