Deca Decastar 150E is a semi-automatic MIG/MAG welder, often used for light-to-medium duty fabrication and equipment repair. It is valued for its versatility, allowing users to switch easily between gas-shielded welding and gasless flux-cored wire welding. Hobart Welding Key Features and Specifications

Ground the unit first (PE terminal to system earth).
Connect single-phase input to L and N.
Connect motor leads to U, V, W (phase order determines direction).
Use shielded cable for control signals; ground shield only at drive end.

ERR01

| Error | Meaning | Solution (from manual) | |-------|---------|------------------------| | | EEPROM failure | Replace mainboard. Attempt reset via r.St in Tech Menu. | | ERR03 | A/D converter not responding | Check power supply (minimum 12V DC). Check internal ribbon cable. | | ERR05 | Weight exceeds max + 9d | Remove load. Check for mechanical binding. | | ERR08 | Underload (negative overload) | Calibration zero lost. Perform C.IN again. Check load cell wiring (Excitation +/-). | | ERR31 | Calibration weight error | Applied weight < 1% of full scale. Use larger test weight. | | Lo BAT | Low battery (if backup option fitted) | Replace internal battery or connect mains. | decastar 150e manual

Device Overview

Q4: The display is very dim. Is there a backlight setting?

A: No. The Decastar 150e does not have a backlight; it uses high-brightness LEDs. Dimming usually indicates low voltage (check 12-24V DC supply).

Place sample centrally on heated stage.
Set stage temperature (e.g., 90°C for fast epoxies, 60°C for sensitive gold wire).
Program dispense time (typically 15–120 seconds) and pulse interval.
