PA-1200

AWS specification: AWS A5.1 E6012

JIS Specification : D4313

Other Specification: NONE

 

I. APPLICATIOINS:

Welding of cars, vehicles, machines and general light structural steel.

II. DESCRIPTIONS:

PA-1200 is a high titania type electrode. Its weld metal has a good bead appearance with shallow penetration. It is suitable for welding of steel sheets and general structures.

III. NOTES ON USAGE:

• Pay attention not to exceed the range of proper currents. Welding with excessive current not only lowers X-ray soundness, but also causes increase of spatter, under-cut and insufficient slag covering.

• Dry the electrodes at 70-100 degrees C for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosities.

• Excessive drying before use causes less in penetration and overheating of the electrode.

IV. TYPICAL CHEMICAL COMPOSITION OF WELD METAL (%):

C	Mn	Si	P	S
0.10	0.40	0.28	0.017	0.010

V. TYPICAL MECHANICAL PROPERTIES OF WELD METAL:

Yield Point N/mm2 (ksi)	Tensile Strength N/mm2 (ksi)	Elongation %	Impact Value °C, J (°F, Ft-Lbs)
430 (62)	500 (73)	27	0°, 85 (32°, 63)

VI. WELDING POSITIONS: FLAT, FILLET, VERTICAL UP, HORIZONTAL, OVERHEAD

VII. SIZE AND RECOMMENDED CURRENT RANGE (AC or DC +/-):

Diameter (mm)		2.5	3.2	4.0	5.0
Length (mm)		350	350	400	400
Ampere	Flat	45 - 100	85 - 130	110 - 160	160 - 220
	V & OH	45 - 100	85 - 130	100 - 150	120 - 190
