RE: DIY Welding
im a alluminuim tig welder by trade and can also do any other kind of welding , if you want to weld alluminium rod for making wheelie bars for eg; i strongly recomend using a TIG welder with a 1.5mm tungsten electrode and sharpen the point of the electrode like a needle because the electrode end always balls up when tig welding alluminium especially when welding delicate fine parts like a wheelie bar made of alloy rod for example . alloy mig welders allways do a dirty job and have a habbit of burning the alloy and goes all black plus alloy mig needs a much higher starting amps to get the alloy melted and welded and IS NOT SUITALBLE for welding fine small alloy rc car parts . If you have a handy spare lazy $3000 you could proberly buy a very small portable TIG welding machine but then you also need to get a botlle welding gas called ARGON , this gas can weld alluminium and stainless and mild steel but then youll need to change the electrodes if you wish to weld other metals , WHITE tip TIG elecrode is for welding alluminuim ONLY and RED tip electrode is for welding stainless and mild steel ONLY
