- Insulated
- non-flamable
- Magnect clamps
- Leather gauntles
(gloves)
- Welding curtain
- Provents arc eye
- Provents arc eye
- Welding mask
- SOLDERING
- A low (but still really hot!!) temperature
process 250 degrees C used to join
non ferrous meatl
- Solder is made from alloy
of copper and sulfer
- Solder melts at
200-250 degrees C
- Soldering can be used to fix
copper and brass because they
would metal at high temperture
- To make a good joint we
clean the metals and use
flux.
- A low (but still really hot!!) temperature

- In school you can use a lathe

- You can use a metal lathe to

- Knurling makes a
rough edge
- To get a good quality
cut you must have a
sutible speed and a
sutible rate
- In school you can use a lathe
to make cylindrical objects
- WELDING
- Mig welding uses an
electric arc to copper
- The weld is protected by
Co2 and argon stops
oxygen causing a brital weld
- Copper wire speed rate
- Voltage
- Gas pressure
- The welding torch
copper,wire,gas and
electric
- Mig welding uses an
