MIG welding contact tips come in distinctive styles.
Adjustable Tips
Adjustable tips allow for quicker changes to the weld size without changing the tip. The moving parts in the tip makes them less sturdy than fixed tips. The adjustable tips are more efficient for jobs with multiple purposes, but the greater frequency of breakdown causes some workers to avoid them.Tapered Tips
Miller is the field's largest manufacturer of arc welding and cutting Accoutrement. Contact tips are used single in welding projects that enlist metal inert Gauze welding (MIG), further called Gauze metal arc welding (GMAW). A contact gratuity is fed wire continuously to supply info for welding, so the immensity of the gratuity Testament figure the bigness of the wire, which Testament fit the dimensions of data available for welding.
Fixed Tips
Constant tips are of a criterion dimensions and can be switched in MIG guns (handheld welding tools). These duty to be changed considering contradistinct sizes Testament permit for antithetic levels of precision, which is decisive for at variance jobs and applications. The wire that is fed terminated the gratuity Testament assent with the gratuity immensity, so the dimensions of welding info Testament correlate to the gratuity size. Fixed tips hold up well and do not need to be replaced as often as adjustable tips.Tapered contact tips are used in situations where there is limited mobility and access to the area in need of welding, such as inside corners. Tapered tips stick further out of the nozzle of the torch, which is bulky and hard to see around in tight spaces, so the longer, thinner tip allows the welder greater visibility and maneuverability. Miller makes tapered tips in threaded and non-threaded forms, although non-threaded are more common with tapered tips as they provide the smallest and most maneuverable end for the MIG gun.
Non-tapered Tips
Non-tapered tips have greater mass on the tip, which provides greater durability for the tip. The greater mass will limit the welder's ability to see around the tip, so it should be used for welds where the welder has good visibility. Non-tapered tips hold up well to heat and last longer than tapered tips, but are closer to the nozzle and allow for less visibility. Miller's non-tapered tips come in both threaded and non-threaded forms, although since non-tapered tips are large already, they often are used as threaded tips since visibility is less of a concern with non-tapered contact tips.
