Thermocouple Welder     

BEL Thermocouple Welder Model: TL-WELD9 is design for manufacturers and laboratory for the production of commercial grade thermocouple junctions, and for users of large numbers of exposed junction thermocouple such as test and development laboratories where multipoint temperature sensing of test pieces is required. It has a safety welding pen design and do not need to use pliers any more. No special skills are needed and most people will be capable of producing quality work with minimal practice. The instrument can be operated via the front panel. It is portable welding machine that allow the thermocouple wires to bond into freestanding beads. Operator only takes a few seconds to bond the standard thermocouple wire into temperature sensors. This model is suitable for welding any type thermocouple wires from AWG40-AWG19 (0.1~1.1 mm) in diameter. A satisfactory thermocouple junction is produced without using argon, Just 3 steps you can weld a quality bonded thermocouple wire sensor. It has been selected by many famous laboratories in global. We Provide Global Speed Delivery Service.
