Thanks for all the advice. The flow meter I bought (fits on the torch) indicated I was using 20 litres/minute, which might explain why I have been getting through so much gas.
I tried again, this time with a gas lens, the correct flow rate, and I cleaned the black oxidation off of the tungstens...
Ok I have ordered a flow meter and a gas shroud and I will try again.
On the subject of bikes, during my SRX ownership I have had, and sold on, an SZR660, DR750, Skorpions and an SV650 none of which have really done it for me. Bike preference is a very personal thing. I built an XL500 engined...
Thanks for the responses. I checked and the flowrate is around 5-8 litres/min. The rods I am using are stamped ER 70 S2 on the flat stamped into the end. I am using a flap disc and electric file to clean up the weld area and have around 10-20mm clear all round the weld. My earth is quite a way...
I am having a lot of grief trying to TIG weld brackets onto a Yamaha mtotorcycle frame. I have spent most of the morning trying to fit a fairing mount to the headstock. In the end I took the cutting disc to it an cut it off.
What I am finding is that the first bead I lay down is often ok with no...
Sort of makes sense. Also with the +ve earth the electrons have to flow down the rod prior to flowing through the workpiece, the rod is fairly restrictive and so the electrons get pre-heated. (Not sure electrons get heated as such, from memory they get 'excited')
Sorry my initial question was a bit rambling. Basically it boils down to.
Why does changing the polarity alter the penetration of the weld, when the current flow is the same, its just flowing in a different direction ?
Ive been doing an evening class the local college with a view to learning MIG, stick and TIG. Something which has puzzled me recently is the polarity on stick welders. Some rod type (low hydrogen ?) require the rod to be -ve and others the rods must be +ve. A couple of times Ive made the mistake...
I need to do a small amount of stainless welding. My machine only takes 5 and 15kg reels. a 5kg reel of stainless wire is expensive, has anyone tried one of these adaptors ?

I purchased a Clarke 160TE several months back and have been very pleased with it. Seems to fairly well put together and has more settings than other similiarly priced sets
I recently purchased a Clarke 160 ET http://www.machinemart.co.uk/product.asp?p=010115161&r=2031&g=105 and have been very pleased with it. I chose this over a number of others because it offered a wider range of settings than the others in its price range. It also seems to be fairly robust and...
Ive finally bought a welder (Clarke 160T) and gas bottle etc, and now have a few questions.
I have been doing a welding course which has industrial welders which are either automatic and only require the thickness of steel to be specified or have a fully variable voltage and speed control.
The...
I searched through the yellow pages and found a local pub gas supplier (strangley enough called 'Pub Gas'). He charges £35 deposit (refundable) + £11 refill for a 10 litre bottle. He was only prepared to fill bottles which cam from him in the first place, so secondhand bottles may be tricky to...
Thnaks for that. The lower lug support the sidestand which is also tearing of the frame (couldnt get a piccy of that). I'll weld in an support between the two section as extra support.
Also whats a 'plug'
I need to repair a crack in a motorbike frame and . Current plan is to drill teh ends of the crack, grind out the crack to about half depth of tube and then run a weld round the tube. At the moment I have no idea of the tube thickness but I would guess around 1.5-2mm.
Does this sound like the...
Thanks for that, the guy at WeldUK was very helpful.he couldnt tell me hwat it was the same as but I managed to find the Sealey SUPERMIG150/5 http://www.sealey.co.uk/PLPageBuilder.asp?gotonode=ViewProduct&method=mViewProduct&productid=8327
which looks pretty close.
Anyone got an opinion on...
Does anybody have any knowledge of ERP welders ? .http://welduk.com/Details.asp?ProductID=73. It looks quite good value but I cannot find any information (good or bad) anywhere
