stacktrace.js v2.0 is out, featuring ES6 support, better stack frames, and more!
The is a versatile, semi-automatic MIG/MAG welding machine manufactured by Deca, designed for both gas-shielded and gasless (flux-cored) welding. Often used for light fabrication and automotive repair, it is known for its compact design and ability to handle various metals, including mild steel, stainless steel, and aluminium. 1. Key Technical Specifications Decastar 150E
A yellow light that illuminates if the machine exceeds its duty cycle, indicating the unit has entered a cooling phase. My first welds,gasless mig | MIG Welding Forum
Supports 0.6mm to 0.8mm wire; can use self-shielded flux-cored wire for outdoor "no gas" applications. 2. Control Panel & Adjustments The front panel of the Decastar 150E features essential controls for fine-tuning your weld: Power Switch: Main ON/OFF control.
operates on a standard single-phase power supply, making it suitable for home workshops or professional environments. Semi-automatic MIG/MAG Input Voltage: 230V, 50-60 Hz Welding Current Range: 30A to 145A Power Consumption: ~1.7 kW Duty Cycle: 35% at maximum output Weight: Approximately 30 kg
Typically features a 4-step power adjustment to match metal thickness.
A stepless manual adjustment dial that controls the rate at which the welding wire is fed into the torch.

stacktrace.js - instrument your code and generate stack traces
stacktrace-gps - turn partial code location into precise code location
In version 1.x, We've switched from a synchronous API to an asynchronous one using Promises because synchronous ajax calls are deprecated and frowned upon due to performance implications.
All methods now return stackframes. This Object representation is modeled closely after StackFrame representations in Gecko and V8. All you have to do to get stacktrace.js v0.x behavior is call .toString() on a stackframe.
Use Case: Give me a trace from wherever I am right now
var error = new Error('Boom');
printStackTrace({e: error});
==> Array[String]
v1.x:
var error = new Error('Boom');
StackTrace.fromError(error).then(callback).catch(errback);
==> Promise(Array[StackFrame], Error);
If this is all you need, you don't even need the full stacktrace.js library! Just use error-stack-parser!
ErrorStackParser.parse(new Error('boom'));
Use Case: Give me a trace anytime this function is called
Instrumenting now takes Function references instead of Strings.
v0.x:
function interestingFn() {...};
var p = new printStackTrace.implementation();
p.instrumentFunction(this, 'interestingFn', logStackTrace);
==> Function (instrumented)
p.deinstrumentFunction(this, 'interestingFn');
==> Function (original)
v1.x:
function interestingFn() {...};
StackTrace.instrument(interestingFn, callback, errback);
==> Function (instrumented)
StackTrace.deinstrument(interestingFn);
==> Function (original)

Turn partial code location into precise code location
This library accepts a code location (in the form of a StackFrame) and returns a new StackFrame with a more accurate location (using source maps) and guessed function names.
Usage
var stackframe = new StackFrame({fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284});
var callback = function myCallback(foundFunctionName) { console.log(foundFunctionName); };
// Such meta. Wow
var errback = function myErrback(error) { console.log(StackTrace.fromError(error)); };
var gps = new StackTraceGPS();
// Pinpoint actual function name and source-mapped location
gps.pinpoint(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Better location/name information from source maps
gps.getMappedLocation(stackframe).then(callback, errback);
//===> Promise(StackFrame({fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Get function name from location information
gps.findFunctionName(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284}), Error)
Simple, cross-browser Error parser. This library parses and extracts function names, URLs, line numbers, and column numbers from the given Error's stack as an Array of StackFrames.
Once you have parsed out StackFrames, you can do much more interesting things. See stacktrace-gps.
Note that in IE9 and earlier, Error objects don't have enough information to extract much of anything. In IE 10, Errors are given a stack once they're thrown.
