Hi,
Please find below the definition of welder and welding operator and tack welder.
WELDER:
A welder is one who performs a manual or semiautomatic welding operation.This includes welding with torch,gun or electrode holder held and manipulated by hand.Part motion devices and manually controlled filler metal feeders may be used.Semi automatic welding is manual welding with equipment that automatically controls one or more of the welding conditions,usually filler wire feed.A welder would commonly perform shielded metal arc,gas metal arc,and flux cored arc welding.

WELDING OPERATOR:
A welding operator is one who operates adaptive control,automatic,mechanized,or robotic welding equipment.Automatic welding is with equipment that reqires occasional or no observation of the welding and no manual adjustments of the welding controls.Mechanized welding is with equipment that requires manual adjustment of the equipment controls in response to visual observation of the welding,with torch,gun or electrode holder held by a mechanical device.Most submerged arc welding setups would fit in to this category.

TACK WELDER:
A tack welder is a fitter,or someone under the direction of a fitter,who tack welds parts of a weldment to hold them in proper alignment until the final welds are made.

Thanks & Regards,
