is nothing simple? changed the reel ,had to take torch apart to get wire through, now its splitter/splatter ,welding on low power it seems even though ive got it on full ,120amps,gas bottle on, has anyone got a diagram of how washers ect; go together,cheers steve

Sounds like it's earthin' out before it leaves the nozzle. What welder is it? I got a few sets of schematics here for some of the smaller hobby welders.

ello lee , its a sealey 120turbo , great bit of kit

Nice, had the 90 for a while, got a gasless sealey now and it's PANTS!

I'll have a look for you, got a Clarkes repair CDROM here somewhere

Lee

cheers mucker , them wide wheels on your car look the bizzo

Can't find this disc I'll have a hunt and post you a diagram as soon as I find it

thanks mate

OK closest I can find this morning is the PDF manual for the 100, but they are pretty much the same welder.

If that is no help let me know and I'll have to find out the engineers repair manual and scan a page or two

Hi,

Whats the condition of your earth lead like? Check where the cable assembly enters the body of the welder. The earth braid inside the cable is crimped into a fitting which in turn is bolted into the cable feed assembly. If, like my welder, it got occasionally tugged around by accident by the cable it can cause the earth lead to be pulled out of the crimp thus causing the bad earth. Tried to fix my 120amp SIP, but ended up having to get a complete new cable assembly.

Check also the earth clamp fittings.

Also, try dismantling the hand torch and check the connections inside.

Hope you sort it out, as a welder that is erratic really messes with your head. Its funny how they usually give up the ghost and need a good kick just as you've manouvered yourself into that really tight awkward postion under the car . Remember, we do this for fun?!

Good luck,

Rich

thanks for your help chaps, its sorted ,i was being lazy when i undone it to investigate yesterday i noticed dirty contacts , anyway , cleaned em all up , done it all up nice and tight, and now it makes that lovely fizzy/buzzy noise as i glide down the metal, with a oneway ticket to smileville, steve

on a similar note , if anybody is wasting their money on disposable bottles of gas, i use a co2 bottle from the pub cellar, if u use the pub as much as i used too u might get it free like me , lasts years,steve

On a related note, what's the general verdict of gassless vs. normal MIG?

I've only used a gassless 90A welder and the results have been, shall we say, variable. I accept that a lot of that is my (lack of) skill as the "laying down underneath" welds are much uglier than the "sqaut down comfy next to the sill" welds I've done in the past.

I was wondering if it's worth getting the gas adapter is all...

laying under a car and welding to the rusted underneath is bad enough with the gas turned up high, let a lone a gasless mig. You are brave!
Even with sheilding gas it takes a fair bit of skill to get a decent weld (full penetration, no blow holes) when gravity is working against you. I tend to find I get drips forming so I use shorter bursts rather than lower current. It's certainly a nice feeling to get topside and see a neat line of weld penetrated through the floor, although I still have to go back under with the grinder and dress the blobs a fair bit

what's the general verdict of gassless vs. normal MIG?

Gasless = bad.
normal MIG = good.

I would invest in a gas adapter if I were you.

I've posted this elsewhere but anyone wanted to get rid of a working gas MIG welder, I can come and collect as long as its near york. PM me if you can help,
Tim
