Tell me about my welder please :)

[Paulpen]

Finally picked it up last night and seems ok but would be nice if the knowledge holders would join in

Its a Magnum welding machine (ive not heard of em either lol) !

Its going to be used firstly to play about with and learn the basicas and then im going to attack my project car.

Ive plugged it in and the fan can be heard and the different wire speeds seem to work.

So here come all the questions

Is that regulator the one I need to connect it to a refillable bottle and what size can I get the bottles in ?

Is that wire correct for what im planning or do I need 0.8 ? Also it seems to have dirty patches along it. The are about 4 inches long every 10 inches but the dirty bit still feels smooth :S

Can anyone tell me what that big table means ?

Sorry !

yes and how tall are you

 

[Paulpen]

Ill rephrase then - whats the nearest size that I can get to scuba diving size bottle ?

 

[Wozzaaah]

Looks in fantastic condition, well done on buying it. If it wasn't for the mark where the bottle's been sat, you'd think it was new!
According to the data plate it's 30-150A, 15-21V and asks for a 20A supply to get full whack out of it but you should be fine on a 13A plug unless you run it at full power for long periods. Ideally stick a round 3 pin 16A plug on it and get a 16A supply rigged up.
Don't run the rusty wire throught it, you'll clog the liner with rust dust. Strip off the layers until it comes good or if it doesn't then dump it and put a fresh reel on. (A reel of wire is cheaper than a liner replacement and a whole lot easier )

 

[Paulpen]

Cool - how do I go about taking the wire out (guess I need to untension it somehow) ? Also what end of the liner do I pull it out ?

 

[Wozzaaah]

See the little holes in the rim of the reel? Snip the end of the wire off before it enters that little black plastic tube on the feed assembly making sure you keep a firm hold of the end to stop it unravelling, then poke it through any of those holes and bend it round to stop it coming out. That's the reel secure for now. Next, loosen that thumbscrew on top of the tensioner and take all the tension off the rollers, you can then pull the rest of the wire out of the torch end. Careful when stripping the wire off, it will do it's utmost to uncoil on it's own and will get into a right mess. You'll probably find it'll be ok after taking off a few layers.

Part 1 complete

Anything I can do to service the torch, rollers etc in the way or lubrication etc ?

dont kno if your intrested but the small bottles (scuba size as you referd to them) cost the same as the bigger industrial bottles becuse they have to be refiled by hand but the bigger ones go on an automated line( well that was the case of energas enyway )
hope it helps

Hmmmmmmmmmmmmm interesting !

How big are the so called big ones ?

 

[Paulpen]

Also another question

Here is a pic of where the wire rollers / tensioner bit are.

They seem to have a kind of copper grease on the tensioner roller and the feeder roller. Should this be here or should I rub it off ?

 

[bucko]

im not shore about the presise size but it is the larger of the sizes you can get from your gas supller

hope the pic helps you to judge its size

This probably a mixture of copper coating from the wire and whatever someone has used as a lubricant, this will only cause the wire to slip on the rollers so clean it off and run them dry.

i have been dooing some serching and i think they are a 50 ltr/kg cylinder
