Mini Arc Logger III


The MAL III: one of the world’s most cost-effective welding monitors

Supplied in a rugged aluminium case, this go-anywhere unit weighs less than 9kg and set-up takes minutes, minimizing onsite downtime. The field-proven sensor probes and IP rated controls mean the MAL III can be used in harsh conditions with the minimum of daily maintenance. An optional waterproof plastic hard case gives further protection for the unit and enables easy storage and shipment.

Key Features

Probes: Monitor welding current up to 2000 amps and voltage up to 100 volts
Welding Processes: FCAW, GMAW, SMAW, SAW and AC/DC GTAW (with protection against HF Arc Starting)
Screen: 5.7-inch TFT
Battery: Allows up to eight hours of monitoring time between charge cycles.
Welding Data Storage: Dedicated 4GB removable memory stick (allowing integration of stored data into to Excel report spread sheet reports, on an external PC using supplied software)
Flexible QWERTY Keyboard (Optional): Enables heading data input facility and easier adjustment of other settings.

The standard base unit will measure and record Welding Current, Arc Voltage and Arc Time and will also calculate and record Arc Energy and Heat Input.

Additional Options

  • Transducers for the measurement of Wire Feed Speed and calculation of total Wire Payoff
  • Welding Travel Speed for automated processes
  • Gas Flow and consumption
  • Type K Thermocouple for measuring Pre-Heat and Inter-Pass Temperatures

An additional Auxiliary input is available which can be factory configured for use with other transducers such as O2 Sensors for recording back purging during the weld, please contact TVC for further information.

The unit is supplied with a 90-240V AC battery charger and has an optional external, portable, hard copy printer for printing weld parameter data during or after the weld process, providing full onsite traceability.
