Guide to Parallel Welding Machines & Underwater Cutting/Welding
How to Put Two Welding Machines in Parallel
When using two welding machines in parallel, a parallel switch with a minimum capacity of 300 amperes is required. This necessitates the use of a double-pole safety switch. Adjusting two variable power machines for parallel operation involves two phases:
Phase 1: Current Adjustment
Each machine should be configured to deliver the same current when operating in parallel, with each machine providing half of the total current.
Phase 2: Voltage Adjustment
The open

Construction Materials
1. – What must we take into account to choose a construction material?
To choose a construction material, we must pay attention to:
– The weather of the place where the building is going to be set.
– The effort that each element of the structure has to support.
– The cost of the material.
– Esthetical condition.
2. – Which groups of construction materials do you know?
Stone, cement, mortar, concrete, plaster. Ceramic,

HTML (HyperText Markup Language)
HTML is the foundation of the web. It’s a markup language that allows you to create web pages. WYSIWYG (What You See Is What You Get) editors make it easy to create HTML documents without needing to know the code.
Key Concepts in HTML:
- Web Template: A pre-designed layout for a web page.
- Link: A connection from text or graphics to another web page or resource.
- Frames: Subdivisions on a web page allowing for the display of multiple content sections.

How to Connect Two Welding Machines in Parallel. When you want to connect two welding machines in parallel, you must use a parallel switch with a capacity of at least 300 amperes. For this, you need a double-pole safety switch. Adjusting two variable power machines for parallel operation involves two phases:
- Each machine should be prepared to send the same amount of current when working in parallel, with each machine sending half of the total current.
- The open circuit voltage of both machines should

Barcelona Pavilion (1929)
Mies van der Rohe (1886-1969)
Barcelona, Spain – Rationalist Style
Materials: Stone (marble, onyx, granite), stainless steel, and glass.
Formal Analysis:
- The pavilion features eight steel pillars arranged in a grid, supporting a flat roof with a daring overhang and a small courtyard with a pond.
- The rectangular marble podium and side staircase lead to an open-plan interior, blurring the lines between inside and outside.
- Walls serve as boundaries, creating a versatile space with
