== Update session for conversion from Clarke 150A unit to ESAB EMP235ic ==
rLab has recently acquired on loan an ESAB Rebel EMP235ic MIG welder which is considerably more capable than the old Clarke 150A unit but it's controls and operation are a little different so people who've completed induction on the Clarke unit are required to have an update session to be inducted on the EMP235ic. This update session is anticipated to take around 20 minutes.

| Safety || Very much similar to the Clarke unit but be aware this machine can output a higher voltage if mis-set. Also as the EMP235ic can output considerably higher currents, darker shades on masks may be called for. This is a 16A unit and should be connected to a 16A or 32A power supply using industrial type extension leads. IfWhen using the bandsaw connection point then be aware of the risk of tripping if the bandsaw is in use at the time.

| Controls || The controls on the EMP235ic are very different, it is controlled via an LCD screen and a menu system. For the level 1 you should only be using the machine in Smart-MIG (sMIG) mode. In this mode you need only tell the welder what size wire you are using and how thick the material to be welded is. You may optionally also set a weld profile but unless you're sure of your needs, leave it on neutral. Gas flow should remain at 8L/min for normal welding operations, optionally increasing to 12L/min for plate above 5mm thick. On very thick materials then you need to be aware that the torch is only rated to 150A so you may need to run quite short duty cycles.
