Title: Arc Welding Equipment


1
Arc WeldingEquipment
  • Prepared by

2
Miller Dialarc 250/250P AC/DC Arc Welder and
equipment
  • E.Q. - What are the parts and functions of the
    arc welding outfit?

3
Power Switch
  • Used to turn welder on and off

4
Range Selector Switch
  • Use switch to select ac or dc welding amperage.
  • High and Low range
  • If amperage is in overlapping range use lower
    range for better amperage control.
  • Do not change position of switch while welding.

5
Amperage Adjustment Control
  • Use control to adjust amperage.
  • Inside dial is ac low and high range.
  • Outside ring is dc low and high range.
  • Do not adjust when circuit is closed.

6
Circuit Breaker, CB1
  • If CB1 opens, weld output drops to the minimum of
    the range selected, and cannot be adjusted by the
    Amperage Adjustment control.
  • Press button to reset breaker.

7
Duty Cycle
  • Duty Cycle is the percentage of 10 minutes that
    unit can weld at rated load without overheating.
  • 100 duty cycle _at_ 100 amps or less.
  • Exceeding duty cycle can damage unit by
    overheating.

8
Cable attachments for AC DC
  • Cables are attached for AC welding.
  • Do not walk on cables.
  • Do not change to DC welding without instructor
    approval.

9
Ground Clamp
  • Must be attached to welding table or metal to be
    welded in order to complete welding circuit.
  • You must clean painted, dirty, or rusted metal to
    get a good ground.

10
Electrode Holder
  • Insulated.
  • Holds electrodes while welding.
  • Do not burn electrodes shorter than 1 inch.

11
Welding Table
  • Must be made of metal.
  • Hang cables on hooks rather than laying on floor.
  • Position exhaust vent near welding base metal.

12
Welding Electrodes
  • Standard diameter sizes are 3/32, 1/8, and
    5/32.
  • 6013 rod is for new metal. Attractive bead.
    Easy to weld with.
  • 6011 rod is for used and dirty metal. Deep
    penetration. Most utilitarian rod for farm and
    ranch use.
  • 7014 rod is a fast fill rod that produces
    attractive welds.
  • 7018 is a low hydrogen rod. Best with DCRP.

13
Welding Helmet or Shield
  • Used to protect face and eyes.
  • Must have a shade10 lens, minimum.

14
Other Equipment
  • Chipping hammer
  • Used to remove slag.
  • Welding gloves.
  • Used to protect hands.
  • Wire brush and file.
  • Used to clean metal.
  • Tongs
  • Used to carry hot metal.
