"Modern Machine Tools" pedal-operated rocker arm type spot welding machines are available in 6,8,10,15,20, and 25 KVA variants, with three standard throat depths to cover almost any application. All machines are composed of steel-fabricated strong structures to eliminate the smallest spot deflections.

Spot Welding Machine
TRANSFORMER: Low leakage (High Linkage) design, adequate cooling and insulation, and winding impregnation for increased dependability and service life.
CURRENT CONTROL A six-position, off-load tap switch can be used to set the current from minimum to maximum value.
TIME CONTROL Solid State Electronic timer to adjust weld duration from 5 to 50 cycles and 1 to 10 seconds to obtain precise and repeatable locations.
WELD PRESSURE A heavy-duty compression spring installed on a pressure rod with a calibrated nut provides adjustable maximum pressure. Here, a particular layout in the machine reduces operator fatigue and enables easy setup.
COOLING Sensors, holders, and arms all have water cooling arrangements with tube connections. (Water supply must be accessed by the user.)
ELECTRODES The equipment comes with one pair of Morse Taper 2 straight electrodes constructed of hardened copper alloy. Other varieties or spare electrodes can be supplied on request.
