Torch help please

[Simon-]

Hi,

I recently bought a Mig welder, and have since found that my brother has left a R-tech 160 amp dc tig in the shed. He has headed away (abroad) for work so has no use for it. I'd like to try and get it working. I think that he may have only used it once or twice.
there is a 3.2 mm electrode in it which i have been informed may be overkill. I was told that for general (light fab) a 1.6mm might suit better and make the machine easier to use.

I have NO TIG EXPERIENCE.

I just would like some help as to identify what type of consumables to buy. ie how to identify the torch type. Im probably not seeing the wood from the trees! tbh

The above is the type of welder. Im purely a hobbiest. Any help would be great. Thanks!!!

States it comes with WP17 head so look for consumables for that

Hi Simon,
Yes, a 3.2 electrode (tungsten) is a bit on the thick side, according to the Miller TIG Handbook even a 1.6 tungsten will be good for up to 150A DCEN (electrode negative). I mostly use a 1.6 for 70-110A or so. The tungstens you buy are not specific for the kind of torch but there are different types of tungsten (with different coloured tips) for different uses. I suggest you read our excellent TIG Tutorial and then see what questions are not cleared up by that. I started out with the Miller TIG Handbook but that was before we had a TIG tutorial on here.
Hope that helps?
