WELDCLASS WC-03766 WIRE HARDFACING PLATINUM CX-1800 GASLESS 1.2MM 4.5KG

Long-Life hardfacing 'MIG' wire for ground-engaging equipment. Very high resistance to abrasion with up to 3-4 times better wear life vs basic hardfacing 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. Requires minimum 140 amps, suitable for use with 200A-250A MIG welders.

• 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

• 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

• VERY IMPORTANT: 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 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 buffer layer of 309 or 312 wire or electrodes. Whilst not essential, pre-heat of 150-350c may be beneficial.

• If applying to high-manganese (non-magnetic) steel, buffer of specialist high-Mn/Cr wire should be used.

• 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 / downhand only (not suitable for vertical or overhead)

• Surface normally relief-checks (forms fine micro cracks) after welding

• Weld deposit is NOT machineable

• Weld deposit IS grind-able
