I've got a project that will involve cutting 100x100x4mm square box section to various lengths and angles. Rather than use an angle grinder I would prefer to use something more consistant for repeat cuts.
I have a Evolution saw, but that's not really up to the job. What would be more suitable...
We have used the metal reel for a while, perhaps I was just lucky, but will go back to a plastic one. The only wire to burn out in the machine is the welding wire itself. Funny it didn't do it before, but looks like lesson learnt.
Just checked. With the machine off I can find no continuity between the ground and the frame. There is between ground and the diodes, but that's to be expected?
Hi Mike, sorry for my description. Inside the torch connector block that plugs into the machine there are two sheathed cables and a much larger unsheathed copper braid that I assumed was an earth. My welder looks nothing like yours!
Thanks guys.
Yes, the wire is on a metal reel, but miles of wire has been used like that. Either I have been lucky up to now, or something has changed.
How do I check for an open circuit on the torch conductor?
Hi, I wonder if I could pick your collective brains again?
A new problem has occurred with my old Butters. When the torch trigger is pulled when welding, the welding wire glows red hot in the machine and sparks fly as the wire holding reel makes contact with the body of the welder. The wire...
There seems to be continuity between the earth terminal on the torch connector block and the wire feed in on the back of the block. Is this normal? There are two live pins on the connector. These show continuity when the trigger is pulled. I assume this is normal.

Replaced the diode, held my breath and tried a weld. It's sorted! Thanks to the guys on this forum my welder is back in operation again. Really appreciate all the help and advice given. Thanks all!!!:thumbup::thumbup::thumbup:
Heads up! Tracked down a replacement Semikron SKR 100/04 diode for not a lot of money. £8.74 is a steal compared with what I've seen! Search the Ashleacomponentsltd eBay shop. I bought two. Shame they don't have the SKN version, otherwise I would replace the lot for that price. Get them before...
Thanks to Jim I found that one of the diodes near the transformers has a short. With a new diode I hope it will be as good as new. :thumbup:
There's a five week delay from the manufacturer for a replacement though.
Jim has kindly given me some tests to do on the machine. He is a great bloke and put it in a way that a numpty like me can understand. Sir, I thank you for your time and patience.
To cap it all my wife had good news from her hospital visit, so a great day all round. :thumbup:
Noticed this on the other side. Manual says the one on the left is the motor field rectifier, one of the components looks cracked. Could this be the problem?
