Hello all.
Am wondering after reading posts how does a person get to use a single phase "brand irrelevant" welding machine which requires a 15amp supply, keeping in mind that our normal power points supplied are 10 amp in 99% of
places I have seen.
Bearing in mind that to ensure your "warranty" is covered the plug must remain 15 amp, and not be filed or fooled with as it is illegal
So where does that leave the poor bloke that want's to do a bit of handyman stuff at
home? let alone a caravan park workshop for repairs if needed.
Am thinking that maybe common sense would prevail in this circumstance "
Hi Paul
Probably you , like many others, are not aware that those welders draw up to 30amps & have to have a 15amp plug to be approved for sale.
The smaller one with 10 amp plugs draw up to 18amps.
The rules are not silly as may seem .
They take into account a diversity factor which is time actually welding over total time in a 10minute period
This "OFF" time while deslagging, fitting another electrode, etc allows the wiring plugs,sockets etc to cool down.
The wiring plugs , sockets can carry higher currents for a short time & by applying a diversity factor ,allowances can be made.
YES the poor bloke should get a 15 amp dedicated outlet installed.
Now what better common sense would you suggest to cope with THOSE sought of current draws than what has been taken into account when drawing up the standards [ diversity factor]
Diversity factor is taken into account in many areas of the standards, or you woud not have more than one or two 10amp outlets on a domestic circuit.
Your mains in would be the size of welding cables except for diversity factor.
THE STANDARDS USE A LOT MORE COMMON SENSE coupled with common sense about safety than many would understand
