mig welding advice required.....................

[Rocket88]

Just bought a slightly mouldy 205 dizzler turbo. which is going to need the attention of the sparkle stick [front strut tops, mainly] I've done some welding in the past, and have managed to attach bits of metal together in a fairly satisfactory fashion, so I bit the bullet, and bought a Sealey 150 gas /no gas welder.

As I'm going to be doing this outside, going to start with the "no gas" option. What [roughly] should various controls be set at to get me started?

Start with lowest setting and about 4 on wire speed, that's what most of my bodywork is set at with the Clark 151, if it sticks turn up heat to setting two and try again, you should not need Max setting on bodywork.

Practice on scraps first to save burning holes in your car.

Turn up wire speed until you can feel it pushing away from the workpiece a bit when you pull the trigger, then back it off so it doesn't.

Thanks, gentlemen, most obliged

Always do a couple of wee test runs on a bit of scrap. on the cheaper machines the setting seem to change willy nilly.

Invest in some Anti Spatter spray,and use liberally to help cut down on the the cleaning up after. ...

Get a hobby bottle of rent-free gas and if needed set up a wind break.

Always start with the wire moving too fast and turn it down to adjust - this stops the wire from burning into the torch and ruining the tip. When your welding sounds like frying bacon it's set right.

Don't bother with no gas . It's shit and will knock your confidence

[scaryoldcortina]

^ yeah, that's true too - I missed the "no gas" bit in the OP. gasless mig is more like an autofeeding arc welder and it's awful. The extra cost of the wire means it isn't even cheaper!

Practice first.

 

The area you are repairing is highly stressed ( a lot of rotten strut tops are not because of lack of protection, but because of fatigue), you dont want your repair coming adrift and causing much embarrassment and loss of mojo.

Set up a wind free shelter. Wind blowing over the weld will cause porosity (full of air pockets like an Aero bar)

 

Use gas, flux core is 'orrible fumey spattery stuff. Bah.

 

Practice on an old panel from a scrappy.
