Handheld 120 IGBT MMA ARC Welder User Guide Safety Tips and Recommendations 4. Fault/Halt Indicator 4.1. A sudden halt may occur and the red indicator on the front panel is lit. 4.2. The welder has exceeded the standard duty cycle which triggers temperature alert due to overheating.
Handheld 120 IGBT MMA ARC Welder User Guide Welding Fundamentals Welding is a relatively simple process for bonding two pieces of metal together. As an example, soldering two wires together is the same concept. To connect the wires, we use heat to melt solder onto the wires to create the connection and a permanent bond and circuit.
