Welding Contact tip produce process

OTC E-Cu Contact Tip

Heat produced in the welding process can impact on the cleanliness and longevity of GMAW consumables. Processes like pulsed GMAW and/or higher amperage applications expose consumables to higher levels of heat, along with applications in which there is a large amount of reflective heat.
The hotter the consumables becomes while welding, the softer the material (usually copper or brass) becomes, resulting spatter to accumulate and premature failure.
It`s important to choose the best consumables for each application. High-amperage applications (above 300 amps) are often best for heavy-duty consumables because they have greater mass and are capable of dissipating the heat more readily. However, if the welding procedure indicates that the contact tip must be changed frequently, a standard-duty contact tip may suffice.
