45-105A 雙金屬電極，5 件組，適用於 HTP 品牌焊槍

I was a little confused about compatibility at first but once I confirmed these match my torch, the cut quality on 1/4-inch steel improved noticeably. The bi-metal construction holds up better than the standard ones I tried before, and the 5-pack is a solid value for the price.

Swapped out my old electrodes for these and the arc starts much more cleanly now. The bi-metal construction really seems to hold up better on thicker steel.

Cut quality stayed consistent through a whole weekend of heavy use on 1/4-inch plate, and the swap-in fit was perfect with zero fiddling. The five-pack means I’ve got spares ready for when the tip finally wears out, which is a solid value for the price.
