MB36 Contact Tips - M6 thread - Genuine Binzel 

The importance of the contact tip must not be overlooked, the contact tip does what it says, makes contact with the MIG wire filler material passing the welding current from the welder through to the filler wire.  The filler wire as it passes through the contact tip wears the contact which is why the contact has to be replaced regularly.  A worn contact tip will not pass the current to the filler wire correctly and will give you poor welding results. 
The contact tip is more important than the amount you need to spend on it, so don't buy cheap contact tips.

These Binzel original standard M6 contact tips are suitable for use with the MB36 and will fit MB36 copy torches also. 
Ecconomic - Cu tips are the standard Binzel low cost contact tip that does the job better than cheap alternatives.  For the welding professional looking to save money on contact tips then Noz-Alls recommend you need to use Binzel heavy duty tips. The extra long lasting performance outweighs the additional cost saving you time and money. Binzel originals, buying the best saves you money and improves your weld.
