Use only devices with S or K characters. Wear dry protective clothing.

Protective clothing

Check environment for fire hazard by welding splashes

Sufficient ventilation at the welding site! Be careful with chrome-nickel steels and coated surfaces!        

Workpiece must have at least thickness of the stud diameter!

Experience with the handling of stud welders!

Audit

If the quality requirements of DIN EN ISO 14555 apply, the welding personnel must have an operator test in accordance with DIN EN ISO 14732!

Select and properly mount suitable chucks, ceramic ferrule holders, foot plates and pillars.

Check the movement mechanism

Move piston against spring pressure, no extraordinary friction! Check Immersion damping (if available)       

Move piston against spring pressure, no extraordinary friction! Check Immersion damping (if available) Check for stains and tension,
Push the stud into the stud holder as far as it will go!

Foot plate with ceramic ferrule holder centric
aligned to the stud!     

Select lift and stud overlap according to stud diameter and material and check with way measurement system (display of ACTUAL values in graphic display / main menu of power unit)!

Mains power must be sufficient be dimensioned! Different observe mains voltage abroad!        

Installation site

Please notice that devices not taken into
closed metallic containers and plants!

Selection of welding parameters

Current: approximately stud Ø x 70 - 80 (90)
Time: approximately stud Ø x 30 - 40

Functional running

Check function sequence
("Start", "Magnet", "Overtemperature" "Ready" indicators and all other indications of device and / or process specific errors and warnings in the main menu)

Electrical connections and plugs

Plugs, connectors and ground terminals
check for tightness!

Cables

Welding cable and control cables
Check damages!

Ground clamps (mass)

Welding position must be metallic cleaned and free of impurities such as tinder, rust, oil and coatings
(zinc)!

Before starting work

Make welding samples at the same materiel for testing welding performance (Mechanic solidity, closed collet)

Perform visual and bending test and
adjust parameters if necessary!
