MANTAMAN Posted May 13, 2009 Share Posted May 13, 2009 Get yourself a good MIG welder and rent a large gas bottle (BOC or Airproducts) the disspossable bottles dont last long You can weld outside no trouble, just as long as the weather is OK, rain dont mix well with electricity and you cant MIG weld in strong wind,it blows the gas shield away.

hoobby Posted May 14, 2009 Author Share Posted May 14, 2009 mig is what i was thinking of what amp rate would be good as i will be doing chasis leg not sure of how thick the plate should be and is it possible to cut the outer skin away without cutting the inner so i can v grove and weld flush....nice and neat.

opel2000 Posted May 14, 2009 Share Posted May 14, 2009 Get yourself off to a Machine Mart and go for a machine over 130 Amps as this will allow you a longer "Duty Cycle" (roughly translates to the amount of time a machine can be used at a given amps setting before the windings or coils start to heat up too much) Also the Machine Mart machines are good allround machines. The Machiine Mart machines have a very very smooth wire feed system over some of the other machines I've used such as the SIP Machines for instance. Gas.... As someone that has done a lot of industrial welding and had my own business producing fabricated welded stainless steel items I CANNOT see the point of ever going to the hassle of renting a large gas bottle, going through the rigmorol of setting up the bottle hire contract, and worst of all finding you have left the regulator on and found that by the time you go back to do some more welding the slight leak from where the regulator hasn't seated 1000% means you have to pay through the nose again for a re-fill.......... Simply put I've been using the disposable bottles for my MIG welding at home for years, they are cheap, readily available, and when you run out of Gas on a Sunday, you can simply nip down Halfords, B&Q or loads of other places to pick up a couple of bottles to carry on welding. I say a couple of bottles as I always have one as a spare. I honestly cannot see the cost effectiveness of going for a big bottle for home welding. Welding Chassis Legs Yes mate it is possible to cut away the outer skin leaving the inner (thicker) strenghtener area in place, as you sound like you know what you are on about I would recommend going onto the RS Components website and ordering a few of the 1mm thick cutting discs, as the ones from RS are a very long lasting disc against a lot of other ones that I used and seem to disintegrate within a few minutes of use, you should find you get a lot of control with your grinder to finely cut into the chassis leg without cutting too deep into the chassis leg strenghtener.
