The gauge on the front says it'll turn down to 40 amps, but I've never had small enough rods on hand to try it out. The 2mm rods were a bit of a challenge on the thin tubing, you might have noticed that I arranged the parts so that at least 1 component of each weld was a thick piece. BTH |

I must admit I hadn't thought of welders being thrown out (it's sacrilege!) and I tend not to look to closely at battered metal boxes. I will now though! Graeme |

That's the same as my cheap Ryobi arc welder, 40-140A. > The 2mm rods were a bit of a challenge on the thin tubing, you might > have noticed that I arranged the parts so that at least 1 component of > each weld was a thick piece. I once had some 2mm rods (might have been smaller, I don't recall), but I think that's as small as I've ever gone. Thin stuff is possible, you just have to be very careful about speed, angle of the rod and of course current. |

A couple of enormous ones were thrown in a skip at Swinburne just before I left. Two problems: too heavy to rescue without a car. And the truck had already left with my belongings. -- TimC As a computer, I find your faith in technology amusing. |
