Line 216:
| 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. If 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.
|-
| Welding || Position, travel direction, and spacing should all be the same, but be aware that the welder often starts out a little rough for the first 1-2 seconds as the sMIG feature learns what you're doing an corrects so if the weld sounds odd when you pull the trigger, DO NOT STOP, give sMIG time to correct before you decide there's a problem. Be aware that although this welder is capable of globular and spray transfer welding mode when in manual settings, globular and spray transfer should be impossible to initiate while in sMIG mode. Weave patterns should be executed more slowly than usual to avoid confusing the learning feature.

== MIG Welder induction - Level 2 ==
Level 2 induction should cover more advanced uses, there will be a charge for level-2 induction to cover the increased cost of materials and trainer time associated with these more complex uses
