Welding Spear guide: crafting, charge, repairs, and safe use

The Welding Spear is a craftable sharp melee weapon with two distinct layers: 18 sharp damage plus 10 fire bonus damage, and a battery-powered explosion around the point of impact. Its 150 battery capacity enables the explosion; the spear still functions when empty, but loses that effect. That makes it a weapon-management problem as much as a spacing problem.

This guide does not claim an exact blast radius, charge cost per hit, or time-to-kill. Those values are not stated in the current cited pages. Instead, it builds a practical route from the verified recipe, stats, charging rules, and furniture-damage warning.

Craft it only after checking the full material bill

The current Welding Spear page lists one spear crafted at a Crafting Bench from:

The finished weapon weighs 3, has 30 durability, and uses three Tech Scrap as its repair item. Its battery capacity is 150. The same page classifies it as Sharp Melee and lists 18 sharp damage with 10 bonus fire damage.

Before crafting, reserve the repair material separately. Spending every piece of Tech Scrap on unrelated construction can leave a damaged spear waiting in storage. The exact rate at which durability is lost is represented on the source as a 75% loss chance; this guide does not convert that into a guaranteed number of swings because combat usage and misses vary.

The source also marks Tech as the research material associated with the weapon. If the recipe is absent from the bench, check discovery and research progress before collecting duplicate ingredients. That is an editorial troubleshooting step based on the documented research field, not a claim about a hidden unlock requirement.

Understand what charge changes

The spear's normal melee function and powered effect are separate:

• With charge, a hit causes a small explosion around the impact point.
• The explosion can damage enemies and nearby furniture.
• With no charge, the spear remains usable but does not create the explosion.

This is the most important operating fact. An empty spear is not broken, and a charged spear is not automatically appropriate everywhere. Fighting beside a Crafting Bench, storage, or another object the player wants to preserve exposes that furniture to the impact effect.

Use charge where splash around a confirmed hit has value. Switch weapons or move the fight into open floor when important furniture is inside the impact area. Since the source does not publish a blast-radius number, leave a generous buffer rather than relying on an invented tile count.

Use a deliberate hit cycle

Reach is useful only when the tip connects. The following sequence is editorial advice derived from the spear's melee profile and impact explosion:

1. Enter the encounter with the target in front, not beside storage or a work area.
2. Stop at the edge of the spear's apparent contact range.
3. Let the target move into a predictable line.
4. Attack when the tip will connect instead of swinging while closing.
5. Step back after the hit and rebuild the same distance.
6. If charge runs out, decide whether 18 sharp plus 10 fire still fits the target or whether a backup weapon is more efficient.

This cycle reduces empty attacks and keeps the explosion centered away from the player's base objects. It does not promise that every enemy can be staggered or kept outside attack range. Enemy size, movement, and resistance still determine whether a spear is the correct choice.

The source-backed data is the weapon behavior. The decision table is editorial planning based on that data.

Recharge without confusing item charge and base batteries

The Welding Spear uses the item-charge system. The Battery (Item Charge) page says any item with the Battery attribute can be recharged at a GATE Charging Station. These facility stations work all day and handle one item at a time.

The same reference lists additional options:

• A crafted Charging Station recharges one item at a time.
• A powered Charging Crate can charge up to six stored items.
• A Crystalline Vial slowly charges items in the equipped player's inventory.
• A Field Battery instantly restores some charge to one item.
• A powered Charging Pad charges items carried by a player standing on it.

The dedicated Charging Station page gives the crafted station a rate of 15 battery per second. At that listed rate, a completely empty 150-capacity Welding Spear needs 10 seconds to reach full charge, assuming uninterrupted power and no other mechanic changes the process. That ten-second figure is a transparent calculation from two source values, not a separately reported game stat.

Do not confuse the spear's internal 150 charge with deployable batteries used to power appliances at night. The relevant action is placing the weapon on a compatible charging device or using another item-charge method.

Plan repairs and backups before leaving base

Thirty durability is enough to make condition visible as a resource, but the source does not justify an exact "hits until broken" promise. Check the item before a route and use the listed repair item, three Tech Scrap, when required.

A practical loadout includes:

1. A charged Welding Spear.
2. Access to three Tech Scrap at the repair location.
3. A backup weapon that does not depend on the same battery resource.
4. A route to a GATE or crafted Charging Station if the spear's explosion is important to the objective.

The backup is not an admission that the spear is weak. It keeps a routine enemy from consuming charge and durability that were reserved for a fire-vulnerable or clustered target. The cited weapon page lists fire as bonus damage, but it does not say every enemy is weak to fire. Check the target's own enemy page before treating elemental damage as a weakness multiplier.

Sharp Melee progression changes the long-term value

The Skills page says Sharp Melee experience is primarily gained by slicing enemies with sharp weapons, and that using sharp melee weapons on resource nodes also grants experience. Each Sharp Melee level adds one sharp weapon damage. The page also lists milestone perks, including Sharp Throwing at level 3, No Survivors at level 9, and later perks affecting bleeding or resistance.

Those skill facts explain why two players can see different practical results from the same 18-damage weapon. This guide therefore avoids a universal hit count. It is more reliable to compare the spear against the current character's Sharp Melee level and the target's documented resistances.

The Welding Spear page lists ThrowWeapon as its secondary action, and the skill page places sharp-weapon throwing behind the relevant perk. Throwing can solve a distance problem, but it also puts the weapon away from the player. Use it only when recovery is straightforward; that recovery advice is editorial, not a claim that throws have a special return mechanic.

Troubleshooting poor results

If the explosion is missing, check charge first. The source explicitly says the weapon still attacks while empty but loses the explosion.

If base furniture is taking damage, move the impact point. The explosion is documented to damage furniture around the hit, so the problem is positioning, not an unexplained durability bug.

If the spear feels weaker than expected, separate three questions: is the battery empty, is the target resistant to sharp or fire damage, and is the player comparing base damage without accounting for skill level? Do not assume the published 18 sharp and 10 fire values guarantee a particular hit count.

If a long route repeatedly ends with a broken or empty spear, stop using the powered hit on every target. Reserve it for fights where the reach, fire bonus, or local explosion creates a clear advantage, then recharge and repair before the next objective.

The resulting role is precise: the Welding Spear is a 30-durability, 150-charge sharp melee weapon with a fire bonus and an on-hit explosion. It rewards controlled contact, open fighting space, and a planned charging stop. It is not a source-backed excuse to invent DPS, blast-radius, or best-in-slot claims.
