Earth clamp amps

[plumber]

Hello I own a snap on 130 mig welder

The welder is quite old and in need of replacement parts

I've replaced the torch,I m in the process of buying a new 24v wire feed assembly as mine has broken

I also need to replace the earth clamp and cable
What amp earth clamp should I buy
I've seen 200,300,400,500

Thanks Tony

A 200 amp earth clamp fitted with 16mm cable (possibly 25mm), anything else is way above your requirements, being as your mig is only 130 amp at most...

some of the ebay low amperage ones look a bit small, rubbish, when you get them, might be worth getting a higher amp one to be stronger, also the max opening of the jaws may be an issue, what I am saying is look twice buy once...

It's worth buying a strong decent clamp and quality cable separately, dead easy to make up.

MIG welders like to have a good solid connection, it makes a big difference.

Ignore the amps - go for a spring clamp that's built well and has plenty copper in it for contact. You're better going overkill rather than underkill.

Can anyone suggest a website I can buy a more robust clamp

Thanks Tony

I have an an almost identical Cebora Turbo mig 130 & I opted for a clamp type earth (part brass) replacement . It’s rated at 400 amps but better over than under rated.

So not a bare end and a G clamp?

I have a 140 machine fitted with a Croc style clip.

But a simple mod to allow a decent cable crimp to hold the cable to it with a M8 nit and bolt.

Always go up to the nearest higher return clamp than the machine max output.

I made the mistake of getting a couple of 400A clamps (Futuris, iirc) from the local shop. They're quite ok and don't seem like crap, but jeez, it's a struggle to open the bleedin' things and clamp them on to something. The 200A clamp I have is much more user friendly, and I think I'll get another couple of those, since most of the time I don't really need the capacity of the bigger ones anyway.

I just used a booster/jump lead cable

Does the job

I think the best clamp depends on the situation. For something which is more or less permanent the Myking screw-type clamps seem like a good option, unlikely to be disconnected if knocked and a strong connection if done up tight enough. For quick jobs or where you want the clamp to disconnect from the material if you trip over it, for example, the standard spring crocodile clamps seem like a good all-rounder and is what I use, although I opted for a solidly built one. When working on large diameter materials a magnetic return clamp might be the most useful.

Thankyou very much for the help

I bought a 400 amp rated clamp very robust but a job to open

I managed to replace the wire feed assembly with a 24volt one on eBay and new torch

Works a treat the wire feed assembly works better than the original

Thanks
