My problem is I turn on the machine, turn on the gas and then hit the trigger and no gas comes out of the solenoid to my gun. I turn off the gas and bleed it and then hit the trigger and the solenoid opens and closes with no problems, but not when there is pressure against it. I've also hit the trigger to open the solenoid and then open the gas and it flows good through the gun. When I let go of the trigger the solenoid shuts off the gas and then I hit the trigger again and it wont open. I measured the voltage to the solenoid and getting a -12.7 dc volts when I hit the trigger, the solenoid is a 24V-DC 6 watt. What do I check for? Need to get this going to finish my project. :( ]]> MIG Welding kiquee http://www.mig-welding.co.uk/forum/showthread.php?t=33300 Machine Shop recommendations in Manchester http://www.mig-welding.co.uk/forum/showthread.php?t=33299&goto=newpost Wed, 16 May 2012 22:26:54 GMT Okay hoping for some recommendations here!

Except i have 6 years no claims and a license for 5 years ( I bought and insured a car whilst i was on a provisional licence for a year)

I've had a few cars,

1996 1.2 corsa - Became bored and was tired car,
1999 1.7 corsa - again, became bored with it,
1988 volvo 740 saloon (2.3 turbo) - Loved it, sadly missed and sold onto a collector, due to a massive hike with renewal quotes.

I really didn't want to part with my loved volvo, £350 it had original 43,000 miles and was in very good shape, hence why i sold it to a collector! It was powerful, but i drive like an old man :laughing:

I know have a 1996 ford fiesta and last year it cost me £987 fully comp.
Well, guess what? Renewal time and its now looking like £1,300...:mad:

6 years no claims, not a single speeding ticket or bumps.

My boss has a 1985 bmw 316 stashed away that has been off the road for 5 years, with nothing wrong with it apart from needing a small amount of welding. It has full bmw history and only sports 59,000 miles with 2 owners from new. £250 Is all he is asking for it..... Great!

Only the insurance is £1700 for it!!!! Its only a 1.8!!

As if i'm going to be hand brake turning and doing donuts and taking every other driver on a drag race from the lights in a 27 year old car.... Insurance really needs to tailor quotes to each individual.... :mad: ]]> The Brew Room SiPMerlin150 http://www.mig-welding.co.uk/forum/showthread.php?t=33298 Belt tensioner puzzler http://www.mig-welding.co.uk/forum/showthread.php?t=33297&goto=newpost Wed, 16 May 2012 20:41:34 GMT Hi,

I'm hoping someone here can help me here because I can't quite figure it out.

With a tensioner pulley between two static pulleys, how much slack is removed from the belt for each unit movement of the tensioner?

The specific application is a cambelt tensioner on an engine. I need to make sure I have enough reserve travel in the tensioner before I go a get a load skimmed off the head.

From some doodles (below) I'm half convinced that moving the tensioner 1mm would pull 2mm slack from the belt, but I'm not sure. The doodle on the left is an exaggerated version of the one on the right.

Any ideas chaps?

Hi I just bought a Dialarc HFE through Ebay the guy said it was all ok and single phase, when I tried to fire it up the fan ran and the main contactor buzzed.I pushed the contactor in with a screwdriver and got power out of the torch. On closer investigation the machine was plumbed in using the buzz bars to 415v. when I changed it to 240v it just blows the fuse and throws the trip out. At the moment I have got it rigged up on a plug top and normal house socket and 16amp breaker.I know this is not enough to use the welder with any great amps but i did expect it to light up and run the fan .

All was fine until:
1) had to change swan neck (welded tip!) and
2) changed up from mini to 5kg wire roll.

It now pauses every few seconds....tried changing tension on spool and on the wire roller but to no avail...

Any ideas?

I thought perhaps change back to mini roll as the 5Kg feels "too much" for the motor..?????

It also producing a lot of black around welds now too....

Thanks for any pointers if you've experienced the same....

When welding stainless, generally 304 and 316, I have noticed lately that the tip of the tungsten gradually seems to go from a sharp point to more of a mushroom when welding. When I start welding with the sharp point I get a beautiful weld, but as the end of tungsten starts to change, the weld pool starts to wander and I lose the nice fine ripples. Material is generally 1.6 mm stainless with either a thoriated or multi-strike tungsten, 2.4mm dia. Seems worse when on pulse, although the multi-strike lasts longer on pulse than the thoriated. Typically I can get one weld round a 2" pipe before I need to regrind.

I’m a newbie here because I’ve just started the long way of welding studying. The first thing I bought for welding is a helmet, and I don’t have a welder yet. The helmet is an old model of Speedglas. The tag on the helmet says that the model is LM 90230. It includes an old style auto dark unit that has only one ON/OFF button and doesn’t have LEDs or indicators at all. So the question is: how I could check if the unit works properly without using a welder? I was told I could turn a 100W incandescent lamp on and then rapidly place the helmet’s face against the lamp, so the glass should get darker in this case. I did that but with no success. Then I checked the batteries and they were OK. So please suggest what I should do next to check the unit?

The story is it came from an auction house and the buyer of the lots took them to a scrap metal place rather than do anythign with them.
There was this Syncrowave and a big Dial arc which was in the skip, complete with watercooler by the time I got there.:mad:

I don't have to pay for it until I have checked if it works although I have been told that it was working fine. I got the panels off it today and it is reasonably clean inside. It was serviced 9 months ago going by the tags on it.













As it had probably been man handled out of the back of a van, there was a couple of relays lying inside. It was obvious to me though where they had come from so I stuck them back in.
There is a dodgy looking connection on the thing that looks like the hf generator.
Also, the "electroslope" panel is all bare. Grommets etc in the front look factory? The wiring is there for it all , but tied off as if unused.
Luckily,my spare torch fits it although the plug for the switch is totally different.
I don't want to have to spend out on parts just to check it's working, only to find it isn't!


Opinions on best way to proceed and/or any contacts for spare secondhand parts greatly appreciated.

I have a pair of used wings that I need to spray for my E30. They are red and I need to spray them black, so just need a colour change.

The wings themselves are perfect and don't need any work on them.

On previously paint jobs if I want to do a colour change, I sand the panel down with 400, high build, sand with 600, then basecoat and finally lacquer.

I have been told that it is not necessary to have to reprimer the panel if the paint is good and doesn't need any work.

How would I go about in spraying the panels? I was thinking of doing the following:
Grey scotchbrite with sanding paste
Basecoat
Lacquer ]]> Paint and Metal Coatings andeep http://www.mig-welding.co.uk/forum/showthread.php?t=33286 springs http://www.mig-welding.co.uk/forum/showthread.php?t=33285&goto=newpost Wed, 16 May 2012 10:09:11 GMT Hi,
