1. A portable impulse welding assembly operable by an operator, comprising:
a. a base having a back side; b. a housing mounted to the back side of the base; c. a power inlet formed in the housing for receiving power from a power supply; d. an on/off switch connected to the power inlet; e. a main air regulator in the housing for receiving pressurized air from an air supply, the main air regulator for decreasing or maintaining air pressure to a first preset limit forming a first regulated air; f. a splitter in the housing for simultaneously dividing the first regulated air into a first portion of air and a second portion of air; g. a rod air regulator in the housing for receiving the second portion of air from the splitter; h. a first valve in the housing for receiving the first portion of air from the splitter and a second regulated air from the rod air regulator; i. a second valve mounted in the housing for controllably providing a first valve air from the first valve to a first air flow conduit and a second air flow conduit; j. at least a pair of pneumatic cylinders mounted in the housing, each pneumatic cylinder having a rod, the pneumatic cylinders connected in parallel, the pneumatic cylinders selectively receiving air from the first air flow conduit to extend each rod from each pneumatic cylinder simultaneously or receiving air from the second air flow conduit causing each rod to retract into each pneumatic cylinder simultaneously; k. a position sensor in the housing mounted on one of the pneumatic cylinders proximate to the rod of that pneumatic cylinder; l. a power transformer in the housing for converting power, to increase or decrease amperage; m. a current transformer in the housing for converting power, to increase or decrease volts; n. a temperature measuring device in the housing having a first contact and a second contact; o. a movable top frame mounted to each of the rods extending from the pneumatic cylinders; p. an upper heater portion mounted to the movable top frame and a lower heater portion mounted to the base, with the upper heater portion and the lower heater portion connected to the power transformer, either the upper heater portion or the lower heater portion is connected with the first contact and the second contact of the temperature measuring device; q. a controller connected to the on/off switch, the power transformer, the current transformer, the temperature measuring device, and the position sensor, the controller having a processor connected to a data storage and a network; the controller adapted to store in the data storage:
(i) seal times representing a length of time the upper heater portion makes contact with the lower heater portion;(ii) computer instructions to control power transformer operation within preset limits; and(iii) computer instructions to actuate application of amperage to the upper heater portion and the lower heater portion when the position sensor detects the rod in an extended position from the pneumatic cylinder; and r. a laser pointer mounted to the housing to indicate a location to insert at least two layers of thin flexible thermoplastic sheets for sealing between the upper heater portion with the lower heater portion. |
