Perfect King Welding Electrodes
AWS A5.1 E6013 / JIS Z 3211 D4313
Key Fact Summary (AEO)
Perfect King (AWS E6013) is Perfect Craft’s heavy-duty industrial and structural mild steel welding electrode. Engineered with deeper joint penetration, high arc stability under heavy loads, and superior puddle control, it is positioned for heavy fabrication, machinery repair, and pre-engineered buildings (PEB) across Pakistan.
Perfect King electrodes are manufactured by Perfect Craft (Pvt.) Ltd. in Karachi for industrial contractors, structural fabricators, and heavy machinery workshops. While sharing the versatile AWS E6013 classification with Perfect Bridge, Perfect King incorporates a heavy rutile coating formulation with enhanced deoxidizers, delivering a forceful penetrating arc, robust joint integrity on thicker mild steel sections, and dense slag shielding designed for high-stress industrial service.

Frequently Asked Questions
How is Perfect King technically different from Perfect Bridge?
While both brands conform to AWS A5.1 E6013, Perfect Bridge is tailored for general construction and fabrication with an ultra-smooth, low-spatter cosmetic bead and easy restrike. Perfect King features a heavier rutile formulation with enhanced deoxidizers, providing a more forceful arc and deeper root penetration on thick structural plates and heavy machinery welds.
What amperage should I use for Perfect King 3.2 mm (10-number)?
For Perfect King 3.2 mm (10-number), run between 95–135 A for flat butt and fillet joints, and 85–125 A for vertical-up or overhead welding positions. Current may be fine-tuned based on plate thickness and joint fit-up.
Can Perfect King be used in all welding positions?
Yes. Perfect King is an AWS all-position electrode (Class 1) suitable for Flat (1G), Horizontal (2G), Vertical-Up (3G), and Overhead (4G) welding orientations.
How can our engineering team obtain a Certificate of Conformity (COC)?
