Daft thought,car battery starter

[rich r]

The main issue is that arc welding is a constant current process, whereas jump starting a car or charging a lead acid battery requires a constant voltage. Also a buzzbox is AC and you need DC for the battery. Whilst OCV may well be around 20V on a buzzbox, that's AC and will vary depending on the current being drawn (which is obviously set and regulated by the welder).

By the time you've adapted it, you'll have spent way more than a cheap battery and a cheap automatic charger (which will keep it topped up) and a set of jump leads.

Why not have a spare battery on a cheap sack truck with a pair of HD jump leads ? Keep spare battery on trickle charge ready to use.

That is the plan from now on,or something like this would be cool

which would suit me as i have a Mk5 transit and in case i have to turn it over to bleed the fuel system can take a lot of cranking power from the battery which soon drains it

Interesting website

I was thinking of the sack barrow with a battery idea too.

For the past few years my Landrover Discovery has been used as the 'trolley -acc' for starting all sorts around the farm yard, from a JCB 3CX to dumper trucks, diggers, fork lifts and so one. Heavy jump leads and leave the Disco engine running to keep up the charge. Hasn't failed yet !

I have a vague memory ( it was late at night and some wine had been taken) of jumping a RR Shadow in Faro from my Mini Moke, using some fencing wire as leads , twisted up three bits to make each lead. Not sure how much livestock escaped, as we neglected to replace it afterwards.

yes thats what they used to wheel out at the garage round the corner from me , to start a flat battery , when i was a kid. A big lorry battery from what i seem to remember.
