Thanks to all who have contributed.
Upon reflection the job will be beyond me, as I can't say that I can control the cooling sufficiently to protect against stress weaknesses after the weld cools.
As I stated earlier, this is one of a few approaches I was considering.
Hi all,
I have a sip hobbymig that my Dear old Da bequeathed to me. The duty cycle is not the best.
I have a fancy for adding an axial fan to aid the duty cycle by keeping the welder cooler for longer. Please bear in mind that the issue is clouded by sentimentality and I know buying a new...
Thanks Piman, that is another option.
Please bear with me whilst I meander off topic...
I have been gifted a 1969 MGBGT and I have a 2 litre Zetec engine to fit. I'm not a fan of the Ford type 9 gearbox, so am contemplating using the original MG gearbox. An Mt 75 or even a type 3 four speed...
Thanks chaps, all of that makes sense to me. I have plenty bits of casting to practise upon prior to having a go at the actual piece.
So in essence, I should mate up the faces, butter them with a high nickel content rod, then weld short sections with, no more than an inch at a time then...
Hi folks, I am exploring the notion of welding two cut down gear box bellhousings to one another in order to change the engine in a classic car.
I'd look to use my big meaty arc welder. I've searched for info upon cast welding and NI rods are recommended, but so is preheating with dissimilar...
Well a huge thank you to you all, A C- curve mcb has cure the problem.
Thanks to everyone who posted.
My next task is to fit a cooling axial fa to my hobby mig...
Well, today I removed the cover of the arc and fired it up. I flip-flopped the switch on and off. It did trip out once, but no sparks flashes or pops could be detected. So I set it up for the 2.6 rods and had some arc welding going on! No tripping the mcb!!!
I ran off a rod and a half, so I'm...
Thanks again for the reply Wozzaaah, I didn't spot any flash with the switch until today...
but as you say, it was exceptionally cheap, although it is very expensive for a welder that doesn't...
Tell you what though, I've learned a hell of a lot this last week! So thanks again.
I'll be...
Aw bum and knickers! Knickers and bum!!!
The problems I have with returning it are:
a, it came from Jormany
b, I have chopped off the schuko plug, as it was a sealed unit surely he won't take it back after that?
c, I'm not sure I can argue what is wrong with it...
The on/off switch...
Thanks to all who have helped. I am really grateful.
The arc welder now has a 16amp blue plug feed from a 32amp mcb. The spare mcb seems to be B rated, from what I can see. The welder runs for much longer and I can actually get some welding done, but if I switch off/ on the welder on it's own...
Aw knickers! I wasn't looking to run it on much above 3mm rods anyway with 2.6/2.5 being the most usual.
Billix! Could I run it from a petrol/ diesel generator?
