ARCCAPTAIN ARC165 Pro 165A Stick Welder: features, specs and who it suits

The ARCCAPTAIN ARC165 Pro is a portable inverter welder that handles stick (MMA) welding and lift TIG, with a maximum output of 165 amps. It weighs 8.2 pounds, runs from 110V or 220V supply, and adds a phone app to the usual controls. Here is what the main features mean and what to check before using a machine like this.

Stick welding at up to 165 amps

ARCCAPTAIN says the welder suits most 6013 and 7018 electrodes. Those are two of the most common rods for mild steel: 6013 is generally forgiving and easy to strike, while 7018 is a low-hydrogen rod often used where stronger welds matter. Output current determines the rod size and metal thickness the machine can handle, so 165 amps typically suits light to medium fabrication and repair work. It is a stick welder, so it needs electrodes, a work clamp, an electrode holder and appropriate protective gear.

Inverter design and dual voltage

An IGBT inverter converts the incoming supply at high frequency, which is why a 165-amp machine can be this small and light compared with older transformer welders. The ARC165 accepts 110V and 220V input. Output on a 110V circuit is typically lower than on 220V, and breakers and extension cords limit what you can draw, so check the manual's duty cycle and current figures for each voltage.

Arc controls: hot start, arc force and anti-stick

The adjustable hot start adds extra current as the arc is struck, which helps the rod light more easily. Arc force briefly boosts current when the arc gets short, which helps keep a steady arc. Automatic anti-stick cuts the output if the rod freezes to the work, so you can free it more easily. ARCCAPTAIN says these combine for a smoother weld.

Easy setup and the LED display

The welder can set current and voltage automatically once you select the electrode diameter or workpiece thickness, and you can still adjust the current by hand. The LED display uses imperial units and has fewer buttons, and ARCCAPTAIN says it can be read without lifting your helmet.

App control

The phone app connects within about 15 metres (49 ft) and lets you view machine status, pick welding modes and change parameters. The brand also lists FAQ answers in the app. Remote adjustment is convenient, but check settings at the machine before striking an arc.

Lift TIG and extras

Lift TIG mode is included, though the torch is not. Lift TIG starts the arc by touching the tungsten to the work and lifting, with no high-frequency starter. The kit includes a shoulder strap and a dust cover. ARCCAPTAIN lists VRD plus over-current, over-voltage, overload and overheating protection, and says the unit has passed TÜV and ANSI tests.

What to check before you buy

• Power supply: confirm your outlet and breaker size, and what current you can draw at 110V compared with 220V.
• Duty cycle: check how long it can weld at a given amperage before cooling.
• What's not included: the TIG torch, gas equipment and consumables are separate; confirm the cables and electrode holder in the box.
• Materials and thickness: compare your typical work with the amperage range in the manual.
• Safety gear: a proper welding helmet, gloves, protective clothing and ventilation are essential. Follow local electrical codes and the manual.
• Phone compatibility: check the app works with your phone.
