Hi Folks,
first post here looking for some help with my Sealey Supermig 150. I bought it second hand a couple of years ago and at the time the seller mentioned the inverter had failed so he replaced it, no problem the welder worked when he demonstrated it so I bought it, when I got it home I found the torch is always live so I put it on my list of jobs to look at later.
Fast forward a couple of years and it's now made it to the top of that job list along with tidying up the insides of the unit.
I don't know a huge amount about welders hence asking you guys for help with what's what, lets start with some pictures of what I've got.
Front Of The Unit
Rear Of The Wire Feed Switch Used To Adjust Wire Speed (I've Unbolted It From The Front)
This Looks To Me Like Another Wire Feed Speed Unit, I Wonder If It's The Original For The Unit And Has Failed In Some Way
Front Of The Wire Speed Feed Unit I Use To Adjust The Feed
A Relay That Hangs Freely Inside The Welder
I Think This Is The Coil That Activates The Wire Feed When The Torch Trigger Is Pulled
This Is The Inverter The Previous Owner Fitted
Don't Know What This Is But I Mention it In The Wiring Shortly
Back Of The Mystery Unit In Picture 3
Don't Laugh, A Very Rough Diagram Of What Wires Connect To Where, The Descriptions Are From The Parts Each Wire Connects To.
The unit in picture 3 and the black relay both hang and swing around inside the welder, I don't like this so once I understand what they are I either need to remove them or secure and tidy there wiring up properly.
So I need your help please to identify why the torch is always live and what needs rewiring to make it work correctly and what the unit in picture 3 and the relay are there for and if they are required or can be removed and the wiring done another way?
Cheers
Chris
