[madkayaker]

sorry it made seance to me. i mean which is the best for welding >5mm mild steel

 

[wyn]

According to the info on this page the coogar 5 is ok up to 6mm and the SG is good up to and over 6mm

 

[Hitch]

Coogar 5 will be ideal for you. A little more readily available too.

thanks

got a bottle of cougar 5 coming Monday

 

[madkayaker]

got my bottle today. When i put the regulator on it it only reads 80 Bar. the label says fill pressure is 200Bar. I am using a CO2 reg with an adapter and there is no leaks so were is the other 120Bar or is it giving false reading as its designed for CO2 (its a good one from weldequip)

 

[backpurge]

"or is it giving false reading as its designed for CO2"

Could well be

 

[malcolm]

The CO2 regs used for welders measure gas pressure. They can be used for argon if the rated pressure is sufficient and you have the adapter.

My guess is the bottle was under-filled. Was it filled by AP or by someone else?

If it was AP it would seem very odd to get an under filled bottle - what is your thinking Backpurge?

 

[madkayaker]

it was filled by AP and was a fresh bottle into the depot as they had to get it in for me. Would the temperature make much difference. The bottle weighs 26KG and an empty weighs 9KG

 

[backpurge]

The temperature wouldn't make that much difference.
I would let AP know you suspect there may be a problem straight away then either try it with another reg or take it back and get them to test it

As Malcolm says it is unusual to get under filled cylinders but having said that it does happen

Another thought.....have a look and see what your CO2 reg is rated to, CO2 cylinders are normally filled to a lower pressure than mixed gases, think it is usually around 150 bar and consequently the regs will have a lower rating, by banging 230 bar through it you may have damaged it and this may cause an inaccurate reading

 

[madkayaker]

The reg is rated to 300Bar will get in touch with Ap thanks for the advice

 

[madkayaker]

have finally got the bottle resolved. Took the bottle back in today and tried my regulator on a different bottle and that confirmed that the fill pressure was 200Bar and my reg was under reading got the bottle swapped over with no problem.
