No it wasn’t trying to feed even when I pulled the trigger 🙂 I’ll be outside again this evening so will do some more checks. It’s been sat for years so this isn’t entirely unexpected. I’ve ordered the new parts anyway on the basis that I’ll get it working eventually 🤞 Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted January 26, 2021 Share Posted January 26, 2021 A couple of handy tips here: Steve 2 Quote Link to comment Share on other sites More sharing options...
landroversforever Posted January 26, 2021 Share Posted January 26, 2021 Worth having a look at the contacts in the torch switch. Mine was being unreliable, sometimes not doing anything and sometimes locking on. A clean up of the contacts and a drop of WD and shes like new. 1 Quote Link to comment Share on other sites More sharing options...

Bigj66 Posted January 26, 2021 Author Share Posted January 26, 2021 What do you reckon 🤨 And the connector end. Not sure of the purpose of this pink wire.... Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted January 26, 2021 Author Share Posted January 26, 2021 A bit grubby but the torch switch works. Quote Link to comment Share on other sites More sharing options...

I can’t see where it would attach either. I have continuity between the two switch wires when it’s pushed. An earth perhaps? Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted January 26, 2021 Author Share Posted January 26, 2021 Took out the rusty wire. I’ll try it again and see if anything’s improved. 2 Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted January 26, 2021 Author Share Posted January 26, 2021 It works! I have a spark so that’s an improvement. When I depress the trigger the feed stops after about 4-5 seconds. Same period every time. Is that normal? Contacts were a bit grubby so some electrical contact cleaner on those. Quote Link to comment Share on other sites More sharing options...
Dr Strangeglove Posted January 26, 2021 Share Posted January 26, 2021 You may have a "spot" or "stitch" timer. It is what you would use on thinner gauge steels so that you weld, cool, weld, cool, etc It may be worth trying to download a manual for it, or put a clear photo of the switches on this thread. Hopefully someone can let you know what each one does Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 26, 2021 Share Posted January 26, 2021 The top two knobs control the spot timer, they are both turned up a bit, so guess this is the issue Quote Link to comment Share on other sites More sharing options...

Bigj66 Posted January 26, 2021 Author Share Posted January 26, 2021 I can turn those spot and rest time switches off can’t I unless I’m spot welding? Quote Link to comment Share on other sites More sharing options...
Dr Strangeglove Posted January 26, 2021 Share Posted January 26, 2021 Yes. Though I am not sure how it works on yours. Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted January 27, 2021 Author Share Posted January 27, 2021 Parts arrived. Is this the correct height of the nozzle relative to the tip? Earth lead is a little large. Will just drill a smaller hole to match the cable. Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted January 27, 2021 Author Share Posted January 27, 2021 Just need some gas and then I can try it out properly. 2 Quote Link to comment Share on other sites More sharing options...
Bigj66 Posted January 27, 2021 Author Share Posted January 27, 2021 Couldn’t find any local gas suppliers other than BOC so I opted for my nearest Hobbyweld dealer in Wrexham. £70 deposit, £35 for the gas and £35 for delivery which although high, will just be a one off due to travel restrictions. Ive gone for the Hobbyweld 5 which is good up to 7mm steel. It will be here tomorrow. 1 Quote Link to comment Share on other sites More sharing options...

Ed Poore Posted January 27, 2021 Share Posted January 27, 2021 @Bigj66 - sorry a bit too late but SGS have distributors in Colwyn Bay, Ruthin and Flint. I've switched from Hobbyweld to them because not only were they better value for money but also a damn sight closer now I've moved back to Wales. https://www.sgsgases.co.uk/find-a-distributor/ Quote Link to comment Share on other sites More sharing options...

Bigj66 Posted January 29, 2021 Author Share Posted January 29, 2021 What’s causing these small indentations to form at the end of the bead? I’ve tried adjusting speed and current but it doesn’t seem to make a difference. I can’t seem to switch off the timer either so it’s stopping itself and these are the longest runs I can do. Best crackle sound I achieved gave this. Look ok for penetration? Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted January 29, 2021 Share Posted January 29, 2021 (edited) I'm sure a reasonably competent sparky could bypass the timer,welds look to be a bit on the cool side, your good crackle seems to be burnt in a bit better, not sure on the indents they don't look to be at the very end of weld so maybe your pulling back a bit too much of the timer issue is not allowing you to finish off, at the end of the day it's all practice and it does no harm to experiment with voltage and side speed regards Stephen Edited January 29, 2021 by Stellaghost 1 Quote Link to comment Share on other sites More sharing options...
landroversforever Posted January 29, 2021 Share Posted January 29, 2021 A good way to look at the penetration is to look at the underside of the weld straight after you finish. You'll see the glow if you've got some decent penetration. 1 Quote Link to comment Share on other sites More sharing options...
