Feel free to contact us with your project requirements.  Generally we would require a material type and thickness to be spot welded, how many spots you may be looking to achieve in an hour and throat depth required.  We are able to offer demonstrations, test welds and advice to help you select the right suspended spot gun for your application.



Tecna Italy are a worldwide resistance welding company.  Back up in the UK on Tecna welding equipment is exceptional and parts availability is very good too.  We still supply parts for 20 + year old Tecna spot welding equipment.
