Profile: International Marking Group specializes in the electromarking/electro-etching process. Our products include marking units, hand markers & accessories, stencils, chemicals, bench markers, and accessories. Our SS-651 is an excellent unit for the low to medium volume user who requires a standard etching unit. Its standard features include medium power transformer, variable intensity control dial, and AC mark DC etch. This unit supplies constant power to the marking head at all times. The output is maintained by the linear rheostat control allowing a variable output level of 0-10 amps, A.C/DC. Our hand marker accessories include rocker marker assembly, universal cord set, neutralyte well assembly, wiping tissue, deep etch pads, marker cartridge, saddle marker and hand marker screens. The electrochemical marking puts permanent marks on conductive metal surfaces. The image created on photostencil/impression stencil is transferred to an electrically conductive surface by the action of electrolyte and electricity.
