- Gas or flux prevents oxidation in the weld
- Weld with or without gas
- Point and pull the trigger
- Great for maintenance, small projects & automotive repairs
METAL TYPES
Mild steel, stainless steel & aluminium
STICK

- Easiest process to learn
- Best choice for quick repairs
- Slower than MIG welding
- Forgiving in dirty/rusty environments
- Not recommended for thin sheet metal welding
METAL TYPES
Mild steel, stainless steel & cast iron
TIG
- Gives a better weld finish
- Accurate heat control
- Considered the most challenging process to learn
- Good way to weld thin material
