Replacing CNC plasma consumables

Do you need to replace your CNC plasma consumables?

CNC plasma cutting is used for precise applications, so it’s important that you maintain your plasma consumables to extend the life of your torch.

Use this checklist to determine whether or not you need to replace your CNC plasma consumables:

1. Get back to basics

When a computer won’t work, 一些聪明的家伙总是问“是不是插入,,en,”以同样的方式,,en,如果您无法达到完美的剪裁,,en,开始用你的火炬最基本的要素,,en,耗材,,en,一个健康的弧是明亮的白色,以颜色淡蓝色,,en,它可能是一个迹象,,en,你的气中的污染物,,en,融化,,en,立即更换耗材您避免完全火炬失败,,en,圆形是一个明确的信号,该喷嘴需要更换,,en,虽然这在很大程度上是由铜,,en,其导电插入件由铪制成,,en,当电弧权力关/开,,en,铪变得熔融并附着到喷嘴的内部,,en,紧盯在坑的地方住铪在喷嘴的尖,,en,这不应该超过1mm进入更深的铪降级,,en,如果超出了深入的工作,,en?” In the same way, if you’re having trouble achieving the perfect cut, start with the most basic elements in your torch: the consumables. Are you using the correct parts for the job, and are they assembled correctly? Make sure all of your CNC plasma consumables are seated correctly in the right places. Consult your operator’s manual, and follow its recommendations for maintenance.

2. Inspect your arc

A healthy arc is bright-white to light-blue in color. If it starts to turn orange or purple, it could be a sign of contaminants in your gas. A green arc is a red flag, indicating that you have burned through the tip on your electrode and are now burning (和 melting) copper. If your arc turns green, replace your consumables immediately to avoid full torch failure.

3. Check your nozzle

Nozzles come in a variety of sizes to accommodate various types of cuts – the more focused the cut, the smaller the orifice. A visual inspection that reveals either an enlarged orifice, or one that has become oval vs. circular is a sure sign that the nozzle needs to be replaced. One thing that isn’t a factor here, though, is color. A discolored nozzle is not a sign of wear. See how your plasma tips can affect cut-quality.

4. Love your electrode

The electrode is a crucial piece in your CNC plasma consumables setup. Although it is largely made of copper, its conductive insert is made from hafnium. When the arc powers off/on, the hafnium becomes molten and adhere to the interior of the nozzle. Keep a close eye on the pit where the hafnium lives at the tip of the nozzle, which should never go deeper than 1mm as the hafnium degrades. If you work beyond that depth, 整个火炬将很快失效,,en,这是便宜了不少更换耗材VS,,en,当你切削钢,,en,在制造等离子体电极中使用的最有效的材料之一是银插入,,en. It’s a lot cheaper to replace the consumables vs. the entire torch.

5. Go for the silver

When you’re cutting steel, one of the most efficient materials used in manufacturing plasma electrodes is a silver insert. Silver conducts both heat and electricity well. When used near the hafnium tip, silver provides much-needed additional cooling and heat-protection. If you want to extend the life of your torch tip, upgrade to a silver electrode.
