Welding Tools - Recent Questions, Troubleshooting & Support
I need a gun for the Hobart beta mig 170 welding machine
Lots of torches are fairly universal and you are likely to find it cheaper to replace only the parts needed if you can find them - manufacturers tend to prefer to sell the torch (or gun) complete with the hose, cables and sheath and they are expensive though considerable savings can be made dealing with factors or independent supplier/repairers.
Most professional mig welders over here use the euro torch and when a welder doesn't have one and the torch is ready for replacing it is a worthwhile modification, especially if the necessary parts can be sourced secondhand or salvaged.
The euro torch just plugs into the machine and once the machine has been modified there are plenty of usable secondhand ones about that can be had for a song.
If you aren't conversant with the euro torch, try a search...

My CLICK Multi Functional Rechargeable
I bought 2 more torches after finding how good the first one was. One failed after a few months, but I had no trouble getting a refund from Bunnings when they couldn't replace it - after all, they are legally obliged to replace or refund if it fails under 1 year old. Today the second one failed, so it wasn't just bad luck! I took the advice of criss994 and opened it up (you need a special screwdriver) - sure enough, the fuse had blown. Soldering a physically larger one in (M205 - 20mm long by 5mm diameter - I didn't have the 10mm x 3.6mm replacement) was fiddley but there is enough room. The original fuse is a fast-blow 1-amp rated one - so perhaps the induction coil feeding the torch causes a surge, as the unit is rated at only 1/100th of an amp. My replacement is a slow-blow 630mA fuse - it should overcome any surge problem.
