HL-WDⅡ Spot welder also can be used to heat treatment to the orthodontic materials. The material for welding and heat treatment is stainless steel wire of the thickness 0.2-1.8mm.

Main characteristics:
① Adopt microprocessor control system, reliable quality, and high control precision.
② Adopt digital display functional mode and power parameter, through membrane button to adjust the parameter, its convenient and concise.
③ Good in safety feature; it has overheating protection system, there’s indicator and alarm function with sub-pressure, overpressure and improper operation.
④ With the welding parameters memory function, when switch on, it will automatically shows the same parameters as the last set, so it’s no need to adjust parameter again next time at the same condition.
⑤ Welding electrodes can be chosen with different combination, it’s suitable for the different weldment.
⑥ The machine has various functions as spot welding, braze welding and heat treatment.
