Series Chassis Welding

[Damonski]

DefenderDan's just been round and given Jess a looking over, pointed out one or two things to look at.

Anyway we got talking about welders and Ive got a Pro 90 Mig from the days of welding on a Fiat 500.

Question is what sort of Ampage would I need for welding on the chassis?

[mark.yellow.series.3]

not as straight forward as picking a magic number. it would depend on the thickness of the particular piece your welding, and whether your laying it flat, or vertical welding, upside down, ect ect.
if you had a scrap piece of metal the same thickness you could set the mig up on the bench before starting on your chassis, if you can do this, the genral rule to set up is to lay down a weld and see if the heat has melted the metal right through to the other side, if your welding vertical back off the power a bit to give your self a little more control.

hope this helps a little.

Yeah I need to get some scrap metal and start playing again. Not had my welder out for a while.

i've welded up my chassis several times with a very very cheap mig welder, basically the smallest my dad could get, and we've never had to turn the power up much to get a decent weld.

the last welds i did i used my stick welder. by gum do i miss that mig.

[mark.yellow.series.3]

i welded every inch of my chassis with stick (2.5's), only because we did not have any migs in at the time, after i finished we got two mig sets back off hire :( , compared with about 40 stick sets :x

I went out and bought a brand new CLARKE gassless mig welder and its totaly ace. You can weld outside in the wind with it no problem. Also non of this Dam run out of gas.  Just wire to worry about. They penatrate alot better than a gas mig aswell because you not got any gas cooling the metal down.

You shoulld be using minimum of 3mm plate, on the 90 that we are currently repairing we are having to use 2 Max on the clarke setting.  On the footwells we will probably drop to 1 max.  Not sure how the thing works other than it burns you!

while were on the subject of welding i have a really daft question... ive decided to try my best and weld up the chassis on mine, now where would i source the metal to weld into place ? and wat would i ask for lol sorry its a daft question but i normally pay people to do stuff  :?  lol

Not sure where in Northampton, next door to where i work (in Bedworth)make protopype body panels and scrap loads, will ask for you.

If i can get some it shouldn't be a problem to get it to you.

[mark.yellow.series.3]

search for 'steel stock holders' but they may only do big sheets, its worth calling in to a fabrication company and asking if you can go through there scrap bin, most fab companies throw out more then youll need. i got all of mine from scrap bins.

[landroverkeith]

cheers guys ill try that

[Miniman]

Yep he is right. I have NEVER paid for any metal up to press. I am the No1 Skip Rat...... You will be very suppriesed what they throw out.

dont forget to ask 1st, as it CAN be classed as theft

[Miniman]

Buy law now you have to have it in writing and dated. Gone are the days of the skiprat....... :(

ive got a gasless mig good tool but a lot of weld splatter from it
did my chassie,stilts and rollcage and the trailer mods
got through loads of wire at £20 for a reel

[Miniman]

£20 a reel..... you dont mean the small reels do ya.... I get them for £10 each.... Our local WeldingWorld.... Mine is a Clarke E150 Turbo. Brill Welder and ya can weld outside with em in the wind unlike gas migs.

TIP for ya. Get one of those Wire wheels for ya grinder it cleans up the splatter so well you could lacer it and it would shine for years....
Very good tool for ya grinder. Always wear a pair of goggles tho as the bristles do fly out every now and then.

[hobbit]

There's a tin of special dipping wax you can use, helps on the splatter and clogging of the nozzle

[Miniman]

Must admit hobbit but never had a problem. People use the spray anti splatter but the gassles is brill...
