Hi Grahame,
I found this link for a Spot Welding Gun Plan
it runs off an arc welder and is similar to the spot weld guns on ebay (international).

I think it would work best with a touch/contact/self striking rod.

Interestimg bit of kit.
I used to use a rod that couçd be laid of the sufaces to be welded and them just dragged along at the appropriate angle and speed. Brilliant.
Not so brilliant- can´t remember the name of them
Try Eutectic. They probably have the required type of rod.

Hi
They sound a bit like iron powder electrodes which pretty much fall under those descriptors.
For those who have n't got a clue what we are talking about - its a rod that can be used with contact of the flux cover on th plate and the arc is operating within a hollow in the flux. This enables a touch welding techniques.
The Japanese shipbuilders,years ago, utilised very long rods of this type for use in mechanical feeders. Many feeders were kept in operation by one man who changed the electrode when completed.
These days the rod is used for a quick build up of deposit.
Iron powder rod flux contains iron oxide which adds to to the bulk of the weld deposit already provided by the steel core wire.
The term contact rods is obscure and out out date .The plans are originally from Popular Mechanics issue of the 50,s or 60,s if I'm not wrong.
Available as 7022 ( semi iron powder) or 7024 codings from all major suppliers.

When I first started welding 47 years ago with my homemade welder I got a packet of Lincoln "Self Weld" rods. They were great , just lay them on the weld line at an angle and they'd strike and run a nice looking bead by themselves. But the joint I got em from moved or lincoln stopped selling them.
That type of rod would be perfect for the spot weld gun

Spot Welding
HI,
I don't know if this of any help or not. My Father had a 'Kelarc' or 'Kel Arc' Spot Welding Gun Years ago. My Brother has it now. It uses 'Carbon Arc Rods'. It just attaches to an Arc Welder at Amps of 50amp and away You go. We use to get the Rods of the Local Welder. It works quite well. I don't know if these are the same Rods or not that Your chasing. If they are then Most Welding Supply Shops and Engineering Supply Shops should have them.
All The Best steran50 Stewart

Been wracking the brain Echidna. Think they may have been Murex. I used a lot of their stuphph until I couldn't get it anymore. I think Liquidarc bought them out.
