MigMaster 250

SERIAL NO: MBKJ704010 through MBKJ706025

SUMMARY: Some of above units have an incorrect gas solenoid installed, which results in low

shield gas flows.

Production has informed us that many of these units were produced using a solenoid rated at 42

Volt AC instead of the desired 24 Volt AC rating. The 42 Volt coil will open slightly but not

enough to allow full flow.

ACTION: Inspect gas solenoid for 42 Volt coil. This is most easily done by removing the left

side panel. The gas solenoid has markings on the side that specify rated voltage.

CONTACT: If you find a 42 volt coil, please call Warranty Service at 843-664-4416, and a

replacement (P.N. 951634) will be shipped. Please have the serial number available.
