sealey 185 supermig

[ag motors]

hi there i have just bought a sealey 185 supermig welder this might be a stupid question but when you switch the welder on the orange light next to the wire speed control does not light up but welder works ok should it light up

Most small MIG's have no "On" light unless it is part of the on/off switch.

It probably is the thermal cutout indicator.
