Martindale Electric Etchers
Three Versatile Etchers for Tool Room,
Machine Shop, or Production Line.

Martindale Electric Etchers write like a pencil on all articles made of iron and steel.  Letters or numbers are burned into the metal making a clear, legible, and permanent record.  Shapes can be more easily etched then stamped.
Electrical etching is quick and easy; merely plug the Etcher in, choose the "heat" best suited to the job, put the work on the ground plate, and begin to write.  For etching large parts that can't conveniently be placed on the ground plate, a ground clamp is furnished.  Depth of mark in the article being etched can be varied by the operator's speed of writing as well as by changing the amount of current drawn.
A Martindale Electric Etcher will quickly pay for itself.  Besides the time it will save, mistakes and thefts will often be avoided if tools, dies, etc., are marked.
In the Tool Room or Machine Shop - For marking tools, dies, jigs, gauges, etc., with such information as type, company name, department symbol, operation symbol, date of purchase, etc., etc.
In Production - For marking inspection data on parts or sub assemblies, for marking hardness data on tools, specifications on nameplates, etc., etc.
This popular low-priced Etcher, has been improved in several ways over pervious models.  It is suitable for all lighter etching applications on smooth iron or steel.

Model C-M Heavy-Duty Etcher

Model C-M has found wide acceptance as a production line etching tool and also in tool rooms where heavy parts are marked.  Its wide range of heats makes it suitable for use on small parts or (on one of the two highest heats) for marking large pieces such as crowbars, shovels, castings, etc.
The case for Model C-M is similar to the No. 5-M Standard Etcher.  Pilot light and "On" and "Off" switch are included.
Features:
Six Heats: 180, 310, 425, 550, 800, 1375 Watts.
Heat taps are taken from the secondary winding - the full primary is always in the circuit.  This permits leaving the etcher connected to the line without danger of overheating when not in use, providing writing point and ground lead are not left in contact.
Case includes storage space for accessories.
