FEATURES:
- For heavy duty work
in auto body repair.
- For light production

starts timer only when current can be applied, which
gives better results when joining coated, dirty or
rusted material.
- Phase shift heat control
permits vernier adjustment of current for welding
light gauge materials and stainless steel.
- Balanced construction
for easy operation.
- Additional arm coupling
to provide larger opening between arms.
- Threaded base for bench
repair.
- A built-in differential
pressure switch operates the timer when the electrode
