Like all thing's get the best you can afford, you can get deals on ebay but it's risky, also depends on what you want to do. if you are outside use gasless mig welder this has wire with flux coating to protect the weld pool from oxygen with gives a pourous week weld, if inside then gas sheild is better, use argon/CO2 mix you can get little bottles but this is expensive so either hire large bottle 'airproducts ltd' or buy bottle look in any classic car mag they have adverts in them, you will need to buy regulator about 25-30 pounds run it at 15psi. Buy highest amp welder you can that will take big reels of wire not the 5kg little ones as you will be forever changing them and the big one's workout cheaper, don't use 0.8mm dia wire it's useless and will keep jaming and kinking go for 0.6mm and 0.6mm tips(look on ebay). These "hobby" welder are ok but don't expect to be able to weld all day as ther thermo cutout will stop play, better with a fan cooled welder but really only use it 1/2 hour at a time then let them cool down as you will find the welder does not give a good weld when it gets hot. Practice, you will not be able to weld up that ride straight away, l was told it should sound thike angry wasps when you are welding right! Good luck  |

mmm bacon! I guess the sound could be described as sizzling bacon or angry wasps. It needs to have a nice smooth fizz to it.
I have recently been using a Clarke 150 amp and a Sealey 150 amp welders, and both are pretty good. Argon/CO2 mix gives a nicer weld, but i have found that if welding upside down, the argon/co2 isn't as good as CO2 only. It seems to cause the weld blob to run back down the wire, but my experience is limited.
I have been using an Argon/co2 mix BOC bottle (biggy with propper regulator) and it really does make a difference over the little bottles. Also, make a puddle of weld and then use a stiring action along the joint to lay down some meaty welds. If at all possible, weld down onto a horizontal surface.

Knock the wire speed up a tad or 2 Only makes a bigger blob to fall onto something flamable (me usually). If you are only going light use, then the Clarke ones seem fine. If you do use small bottles to start with, make sure you take the regulator off when you have finished. Mine leaked slightly, so it would let all the gas out over the course of a week or so. |
