MG 710
TIG
PREMIUM QUALITY MEDIUM
HARDNESS ALLOY FOR MOST AIR
HARDENING TOOL STEELS
DC STRAIGHT POLARITY (DC-)
GENERAL CHARACTERISTICS:
Unique chemistry makes this TIG filler outstanding for the repair of most “air” hardening
steels. Deposits are highly crack resistant, forgeable and temperable. Any number of
passes can be made. Furthermore, repairs can be made in all positions.
APPLICATIONS:
Ideal for repair and build-up of shearing blades, planer plates, anvils, woodworking tools,
percussion drills, earth borers, pressure rollers, clamping tools, worm conveyors, mixer
arms, rollers, shovel and dredger teeth, crusher jaws and rings. Also for machine parts of
steel, cast steel, and manganese steel which are subjected to grinding wear combined with
strong impact.
TECHNICAL DATA:

Sizes: (in) 1/16” 3/32” 1/8”
(mm) 1.6 2.5 3.25
PROCEDURE:
Use direct current straight polarity. One hundred percent argon gas is recommended.
Adjust the amperage according to the base metal thickness and the amount of deposit
required. In general it is not necessary to preheat, but if the base metal is of high carbon
content, it should be preheated to approximately 750°F. If the base metal is known follow
the tool steel welding procedures. Final tolerances may be obtained by grinding
