These machines are precision-built, with careful design and robust construction, suitable for a long trouble-free service. Each machine is submitted to rigorous proving tests before delivery is made, in order that the machine may be ready for immediate installation and operation at customer's works. The "KNOW-HOW" which enables MECHELONIC ENGINEERS to offer these machines, which are included in the widest range of resistance welding and ancillary equipment, is backed by many years of experience in Welding Technology and conforming to IS:4804 and RWMA Standards.
Machines covered under this bulletin are single phase AC for seam welding application in the manufacture of Drums & Barrels, Fuel Tank, Silencer, Muffler, Shock Absorber, etc.
SPMS AND THREE PHASE D.C. MACHINES: Mechelonic Engineers have in their range a number of SPMs for seam welding applications for jobs, such as fully automatic barrel & shell welding (longitudinal), tub cover welding (circumferential), shock absorber welding, fuel tank welding and other automobile components. Mechelonic Engineers also have seam welding machine with 3 phase DC transformer and matching controls.
SPECIFICATIONS: RATING KVA: 50, 75, 100, 150, 200
CONSTRUCTION: Robust Construction, streamlined appearance with maximum resistance to deflection. Welding Transformer enclosed in the main frame, pneumatic controls mounted on the side of the machine.
WELDING TRANSFORMER: Conforms to IS:4804 Part-I and RWMA Standards, water cooled, class 'F' insulation with thermoswitch protection from overloading.
CURRENT CONTROL: Welding current adjustable from 50 to 100% by means of tap change links.
COOLING SYSTEM: Thyristors, Transformer, Secondary connections and electrode wheels are water cooled.
ELECTRODE FORCE: Upper ram is actuated by heavy duty 2-way pneumatic cylinder, controlled by solenoid valve. Compressed air at 2.0 kg cm. sq. to 5.6 kg. cm. sq. provides the electrode force.
Air filter, lubricator, regulator, pressure guage are provided as standard accessories.
ELECTRODE DRIVE: Machines are provided with different drive system depending on the application. Customer to specify the preferred system. 1) Direct Drive Direct gear drive is given to any one of the wheels. 2) Knurl Drive: One of the wheels or both are driven through a serated hardened wheel depending on the style of welding. Constant dressing of weld wheel to maintain uniform profile, constant welding speed irrespective of weld wheel diameter are some of the advantages of knurl drive system.
NARROW TRACK SEAM WELDING: In order to weld coated sheets for application like fuel tank, machine with narrow track welding (2.5 to 3 mm weld width) facility could also be supplied.
In narrow track seam welding, weld wheels are of thickness 6 mm constantly coined for circular profile which results in narrow contact with very high pressure density. Due to this high pressure density the coated material on the sheet metal is squeezed out during the welding.
MOTOR DRIVE: Machine will be supplied with drive system comprising AC squirrel cage induction motor, DOL Starter, Reversing Switch, Mechanical Speed Variator and Reduction Gear Box as standard. Other types of drives including DC drive on request.
MICROPROCESSOR BASED WELD CONTROL: (Optional at extra cost) Machine can be supplied with Microprocessor based control. (For details refer Mup Spcn.)
