709AD is an upgrade model based on 709A, we gave an automatic cooling fan to it, the fan will work automatically when the machine's inner temperature gets higher than a certain value, this improvement effectively extends the continuously working time of the machine.
When you weld different thickness of nickel strips or something else, you need to change the pulse settings to adjust the energy output. We added a LCD display to this model to present the instant working status to you, this is also one change of 709AD.
The copper welding needles would be oxidized after a period of welding, this oxidation layer may influence the welding effect. To solve this problem, we added a mini grinder in the package.
