Gasless Hardfacing Platinum CX-1800 1.2mm 15 Kg 300mm Mig Wire Weldclass WC-03767

DESCRIPTION:

Long-life hard-facing 'MIG' wire for ground-engaging equipment. Very high resistance to abrasion with up to 3-4 times better wear life vs basic hard-facing wires*... thanks to special carbide additives not found in other wires.
Recommended for metal-to-earth applications where wear is mostly caused by abrasion, with low-to-medium impact; points, tynes, buckets, teeth, screws, augers, grousers, etc.
Gasless wire for easy application. Available in 1.2mm in 15kg or 4.5kg spools. Requires minimum 140 amps, suitable for use with 200A-250A MIG welders.

FEATURES:

• High-performance, offering exceptional wear life
• Very high abrasion resistance, offering a wear multiple of ~600% vs mild steel
• Light-to-medium impact resistance
• Gasless flux-cored wire
• Available in 15kg and 5kg spools

APPLICATION INFO:

• Typical hardness 59-61 HRc / 615-645 HB (max hardness achieved with 2 layers)
• Ideal for ground-engaging agricultural and earthmoving tools subject to high abrasion and low-to-moderate impact

SURFACE PREPARATION:

• VERY IMPORTANT: The surface to be hard-faced must be clean and free of rust, scale, grease, moisture & other contamination.
• If existing/old hardfacing deposits are loose they should be removed. (Hammer test can confirm bond strength of existing deposits, a "ping" indicates good bond, and a "clack" indicates a separation layer which must be ground off).
• Buffer Layer / Pre-Heat: CX-1800 will typically weld easily to most common surfaces WITHOUT the need for a buffer layer or pre-heat, such as mild & high carbon steel, cast steel, etc.
• If applying to hard-to-weld steels, or hard-to-weld existing deposits, use a buffer layer of 309 or 312 wire or electrodes. Whilst not essential, a pre-heat of 150-350c may be beneficial.
• If applying to high-manganese (non-magnetic) steel, a buffer of specialist high-Mn/Cr wire should be used.

OPERATING DATA:

• Polarity: DC+ (torch/wire positive)
• Typical parameters: 140-200A @ 18-22V
• VERY IMPORTANT: Amperage & voltage should be as low as possible within the recommended range. Applying excessive heat/voltage will reduce the performance and wear life of the weld deposit, due to excessive alloying with base material.
• Layers: Suitable for multi-layering (up to 3 layers)
• Positions: Flat/down hand only (not suitable for vertical or overhead)

FINISH:

• Surface normally relief-checks (forms fine micro-cracks) after welding
• Weld deposit is NOT machineable
• Weld deposit IS grind-able
